An Introduction to Fellowes Plastic Comb Binding Machines

An Introduction to Fellowes Plastic Comb Binding Machines

If you've been shopping for a plastic comb binding machine, perhaps you've come across the name "Fellowes." Fellowes is a company that manufactures some great products and this article will introduce you to the company's lineup of plastic comb binding machines. All of these machines have two-year warranties, as well as document sizing guides, vertical loading mechanisms, and comb storage trays. They also come with binding starter packs to help you get binding in a hurry. So read on and get ready to meet the Fellowes plastic comb binding machines!

* Starlet. This is Fellowes' most basic comb binding machine. The Starlet has a punching capacity of 7 sheets and it binds documents that contain up to 90 pages using combs that are 1/2" thick and smaller. This machine is designed for occasional use both at home and in the office, and even at school, so it's good if you need a binding machine but won't be binding everyday. Since this is such a basic machine, it lacks a lot of advanced features such as disengageble dies and a depth of punch margin control. Still, for basic binding needs, it's hard to beat the Starlet.
* Star. The next step in the Fellowes lineup is the Star. The Star is similar to the Starlet, although it has greater binding and punching capacities. It can bind documents up to 150 pages long (3/4" thick) and it can punch 10 pages per lift. Like the Starlet, it lacks a lot of advanced features, but it would still be a good choice if you need a binding machine for casual use.
* Pulsar and Pulsar E. The Pulsar (and its electric counterpart, the Pulsar E) is the mid-range Fellowes plastic comb binding machine, and it can produce documents that are up to 300 pages long. (Its punching capacity is 15 sheets.) The manual version of this machine has an ergonomically friendly handle that can comfortably be used by both righties and lefties, and the electric machine can punch and bind with the touch of a button. These two machines were designed for moderate use in small and medium-sized offices
* Quasar and Quasar E. These machines are some of the most advanced comb binding machines that Fellowes produces and they're designed for frequent use in mid-sized and large offices. Both the electric and manual versions of this machine can punch up to 20 sheets of paper and bind documents containing 500 pages (which is equivalent to two inches thick). You can use both round and oval-shaped combs with these machines (oval ones are a must for binding longer documents), but keep in mind that the machine doesn't have releasable pins, so you'll be limited to producing letter-sized documents.
* Galaxy and Galaxy E. These products are the true stars of the Fellowes plastic comb binding machine lineup and are manufactured for heavy-duty use. The Galaxy (and its electric sibling) has the highest punching capacity of any Fellowes comb binding machine: it can punch 25 pages at once, which is impressive. (Its binding capacity is the same as the Quasar's.) The Galaxy has some advanced features that should make it appeal to anyone who needs a feature-heavy binding machine. First, the machine has three releasable pins, so you can bind several different sizes of documents, including A4 size, so the machine is really very flexible. The Galaxy also has a detachable binding mechanism so you can increase your output by having one person punch and another bind.

Now that you know all about Fellowes plastic comb binding machines, choosing the right one should be simple. Whether you need a machine like the Star for simple binding projects or you're intrigued by the more advanced features of the Galaxy, you can be sure that there's a binding machine that is perfect for you.

Plastic Contract Manufacturing

Plastic Contract Manufacturing

Plastic contract manufacturing is the process of manufacturing plastic products on a contract basis. There are many contract manufacturers of plastic products, rubber products and other specialty chemical products. They produce fabricated and extruded plastic products. The plastic fabrication facility of most of the plastic contract manufacturers include the latest Computerized Numerical Control (CNC) routers, mills and lathes for top quality machining of plastic parts and products. Plastic contract manufacturers handle plastic fabrication, CNC machining and CNC turning projects. They usually make plastic products from both natural and synthetic materials. Contract manufacturing of plastic provides plastic products of high abrasion resistance, high tensile strength, high tear strength and good oil resistance.

Plastic contract manufacturers usually make plastic products, components and assemblies at the lowest possible prices. They work together with their customers to determine the materials needed, time taken, design specifications, production developments and certifications required. Contract manufacturers of plastics come up with plastic products in any size, design or quantity, according to the needs of the customer. Most contract manufacturers have a full range of services for design engineering and manufacturing of plastic products.

Plastic contract manufacturing mainly focuses on the quality, repeatability and performance of plastic products. Some contract manufacturers specialize in producing the plastic components for high precision electronic and electrical products, consumer products, automobile products and parts. Many of them also manufacture the press components and precision components of other engineering plastics. Plastic contract manufacturers usually manufacture containers, jars, jigs and fixtures. Generally, contract manufactures use advanced technologies in injection blow molding and compression molding to produce high precision components for electronics and electrical plastics. The materials used in plastic contract manufacturing include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC) and high density polyethylene (HDPE).

Injection molding is widely used for thermoplastics. This process avoids the hardening of plastic in the machine. Injection molding helps to produce more accurate moldings having better control on the material usage. Many contract manufacturers of plastic specialize in the manufacturing dies for injection molded products such as plastic compounds, fan regulators, fan regulator switches, electrical rotary switches, fuse boxes and other special purpose machine parts.

Contract Manufacturing provides detailed information on Contract Manufacturing, Contract Manufacturing Services, Medical Contract Manufacturing, Medical Device Contract Manufacturing and more. Contract Manufacturing is affiliated with Equipment Manufacturer Suppliers.

Extrusion Coating Machine suits short production runs.

Flex-Master Provides Affordable, Versatile Efficiency for Short Runs

Extrusion Coating Machine suits short production runs.

June 5, 2003 - Flex-Master 1300 extrusion coating machine handles runs of 1–2 hr for flexible packaging structures, including LDPE, LLDPE, m-LLDPE, Surlyn, and EVA. Coating speed is up to 300 m/min for 1000 mm dia finished rolls. The 65 and 75 mm co-extrusion stations use feed-block and 1500 mm die with internal deckles. Three-roll laminator has linear-nip arrangement, 450 to 760 mm chill roll, 200 mm water-cooled back-up roll, 165 mm water-cooled nip roll, and closed-loop water circulation system.
Pawcatuck, Conn.)-Davis-Standard's newly introduced Flex-Master 1300 extrusion coating machine is a cost-effective option for smaller production capacities. Engineered for short runs of one to two hours for common flexible packaging structures, the Flex-Master combines several widely-used Davis-Standard machine components into one integrated package. The machine's machine's versatility enables processors to extrude LDPE, LLDPE, m-LLDPE, Surlyn and EVA. Coating speeds up to 300 meters per minute are attainable in 1000mm finished roll diameters.

Modular components include an extrusion station, anchor coater, turret unwind and rewind, sandwich unwind and laminator. The 65mm and 75mm coextrusion station on display at CMM utilizes a feedblock and 1500mm die with internal deckles for edge bead savings. Both extruders are of the MAC (metric air-cooled) design with a single air cooling blower. Advantages of the carriage include motorized traversing movement and manual height adjustment. The coater includes a two-roll direct gravure, enclosed pan-fed system, arch dryer and exit pull roll stabon. The turret unwind and rewind feature regenerative spindle motors and drives, as well as dancer tension control and shafted operation. The three-roll laminator is equipped with a linear nip arrangement, 450mm to 760mm (18- to 30-inch) chill roll, 200mm (8-inch) water-cooled back-up roll, 165mm (6 1/2-inch) water-cooled nip roll, and closed loop water circulation system. These modular components can be combined to create monolayer, coextrusion and tandem coating machines.

This invention resides in the chemical arts. More particularly, it relates to the chemical art having to do with synthetic resins derived from l-olefins, also known as alpha olefins. Specifically, it relates to synthetic resins formed by the polymerization of propylene, and to film made therefrom.


The synthetic resin formed by the polymerization of propylene as the sole monomer is called polypropylene. While "polypropylene" has been used from time to time in the art to include a synthetic resin formed by the copolymerization of propylene and a minor amount of another monomer, such as ethylene, the term is not so used herein. The resin generally is a mixture of propylene homopolymers of different chain lengths and thus different molecular weights. However, it usually is referred to simply as "polymer".

The well-known polypropylene of commerce is a predominantly isotactic, predominantly crystalline, thermoplastic polymer. It is formed by the polymerization of propylene by Ziegler-Natta catalysis. As is well known, in such catalysis the polymerization catalyst comprises the reaction product of an organic compound of a metal of Groups I-III of the Periodic Table (for example, an aluminum alkyl), and an inorganic compound of a transition metal of Groups IV-VIII of the Periodic Table (for example, a titanium halide). The polymerization conditions generally are well known also.

Such polypropylene has achieved tonnage use in many applications, one of which is the manufacture of film, especially biaxially oriented film used in the packaging of, for example, snack foods such as potato chips and the like. Indeed, such film has become known as "BOPP" film.

Oriented polypropylene film generally is made by a method comprising solid state orientation. One such method is the tubular blown or double bubble method. Another is the tenter frame method.

In one embodiment of the tubular blown or double bubble method, a composition consisting essentially of polypropylene is melt extruded through an annular die to form a molten tube which is brought into contact with an internal, cooling mandrel where it begins to solidify. The tube is further cooled in a water bath, and pulled through a pair of rolls which compress it tightly. After passing through the rolls, the cooled, solidified tube is "softened" by reheating with, for example, radiant heaters to a temperature below the melting point of the polypropylene, but high enough to enable the tube to be expanded by internal air pressure. The tube is insufflated by air under pressure. This causes the tube to enlarge and form a controlled bubble, thereby stretching the wall of the tube in all directions, and thereby biaxially orienting it. The bubble then is collapsed through frame rollers, between a pair of nib rolls, and passed through a slitter where the flattened bubble is slit into a strip or strips which is or are wound on a take-up reel or take-up reels.

In the tenter frame method a composition consisting essentially of polypropylene is melt extruded through a slot die to form a molten sheet. The sheet is solidified by quench cooling onto a cast roll. In the on-line orientation practice of this method, the resulting cast sheet is immediately reheated to a temperature below the melting point of the polypropylene, but high enough to enable the composition to be drawn or stretched. In the case of sequential orientation, the thus "softened" cast sheet is drawn by rolls rotating at different speeds of rotation such that the sheet is stretched to the desired draw ratio in the longitudinal direction (machine direction). The thus uniaxially oriented sheet is subsequently clamped at its lateral edges by chain clips and conveyed into a tenter oven where it is again reheated to such a temperature, and drawn in the transverse direction to the desired draw ratio by means of the chain clips which are diverged in their forward travel. The resulting biaxially oriented film is released from the clips, edge-trimmed, and wound on a take-up reel.

Under development in recent years has been the polymerization of l-olefins by metallocene catalysis. In fact, the development of such has reached the stage at which at least one polypropylene producer has made commercially available samples of predominantly isotactic polypropylene produced by the metallocene catalyzed polymerization of propylene. In such catalysis the polymerization catalyst comprises the reaction product of a metallocene and a compound such as an alumoxane, trialkyl aluminum or an ionic activator. A metallocene is a compound with at least one cyclopentadienyl moiety in combination with a transition metal of Groups IV-VIII of the Periodic Table.


The U.S. Pat. No. 5,530,065 to Farley, et al. (see also WO 95/13321), discloses a blend of (a) a metallocene catalyzed polymer with narrow molecular weight distribution and composition distribution, and (b) a conventional Ziegler-Natta catalyzed polymer with broad molecular weight distribution and composition distribution. The blend is disclosed as being useful in heat sealable, unoriented or oriented film. The patent generally discloses making unoriented film by extruding the blend in the molten state through a flat die and cooling. It discloses making oriented film by the blown film method, that is, by extruding the blend in the molten state through an annular die, blowing and cooling to form a tubular film, and then axially slitting and unfolding to form a flat film.

Although the patent discloses that the polymers can be formed by polymerizing or copolymerizing one or more of C2 -C12 alpha olefins, examples of which include propylene, the more specific disclosures are focused on polyethylene and ethylene copolymers. The patent is silent on properties of propylene homopolymers made by metallocene catalysis, properties of propylene homopolymers made by conventional Ziegler-Natta catalysis, and on the more specific temperature conditions in the disclosed ways of making film.

The PCT published application WO 96/11218, the publication date of which is Apr. 18, 1996, discloses a multistage process for the polymerization of one or more than one olefin of the formula CH2 .dbd.CHR in which R can be alkyl having 1-10 carbon atoms. In the first polymerization stage one or more than one such olefin is or are polymerized by Ziegler-Natta catalysis to form particles of a first polymer. In the next polymerization stage, a polymer of one or more than one such olefin is formed by metallocene catalysis on or in the particles of the first polymer. However, except for the end products of the Examples of the application, which end products are so-called impact copolymers of propylene, and which are made by seqential polymerization of propylene and a mixture of propylene and ethylene, the application does not disclose properties of the products of the process.

The published European Patent Applications, EP 0 841 371 A2, EP 0 841 372 A2 and EP 0 841 373 A2, of Mitsui Chemicals, Inc., disclose a propylene polymer composition, the desired MFR of which is 5-50 g/10 min, which comprises a propylene polymer (A3) prepared by Ziegler-Natta catalysis, having a desired MFR of 0.01-30 g/10 min, and being at a desired concentration of 10-90% by weight, and a propylene polymer (A2) prepared by metallocene catalysis, having a desired MFR of 30-1,000 g/10 min, and being at a desired concentration of 10-90% by weight. This composition is stated to be excellent not only in heat resistance, rigidity and tensile elongation at break, but also in moldability.

One of the most interesting innovations in blow molding at K 2004 will be a top-and-bottom blowing system that is said to double bottle output. For energy savings, there are also a couple of new all-electric extrusion blow machines, plus a wheel machine with an electromechanical clamp and a one-stage stretch-blow system with electric injection unit. In addition, there will be a wide variety of extrusion blow, injection-blow, and stretch-blow machines with various enhancements aimed at higher productivity, increased versatility, and faster mold changes.

Extrusion blow variety
Bekum plans to demonstrate a new multi-cavity extrusion blow process, called tandem extrusion blow molding, on its BM-206 shuttle machine. Tandem blowing reportedly doubles the productivity of a standard machine by blowing two rows of bottles—one from the top and one from the bottom—simultaneously. Bekum developed this process for single-serve 100- to 300-cc bottles for milk-based beverages, sports drinks, and juices.

Meanwhile, the ranks of all-electric machine suppliers slowly expands, as Plastimac SpA of Italy (represented here by American Jet Stream) will launch single- and double-station electric shuttles that deliver low energy consumption and are oil-free. The PB1/S has two cavities, clamp force of 3.5 tons, and a 50-mm extruder. It is targeted for 1-liter cosmetic bottles. The PB5/D is a double-station electric unit with six cavities, 80-mm extruder, and clamp force of 10 tons. It’s aimed at 5L detergent and oil containers and has an output of 2400 bottles/hr.

SFR 9/27 reheat stretch-blow machine
Sipa’s new, highly flexible SFR 9/27 reheat stretch-blow machine makes PET bottles from 0.6 to 3 liters.

A new shuttle machine, described as “value-packed” with lots of features at no price premium, will be introduced by Uniloy Milacron. Model UMS 16D boasts an exceptionally small footprint, tiebarless accessibility to the mold area, in-machine trimming, and closed-loop position and speed control. It can handle two to six parisons in single- or dual-station configurations. Clamp movement is strictly horizontal, so the machine can accommodate a bobbing extruder. This model was designed to accept existing molds built for almost any other machine—no other machine is so adaptable, Milacron claims.

Graham Machinery Group will focus on reciprocating-screw technology and will introduce a proportionally controlled, high-speed hydraulic clamping system for high-cavitation molding of gallon dairy containers. Graham will show a cutaway of an air-cooled reciprocating extruder, a standard feature on its newer machines.

Graham will also highlight its latest high-throughput extrusion heads for polycarbonate water bottle production and other applications on its Hesta-Graham linear shuttle machines.

New from Jomar is a version of its EBM 6.0 extrusion blow machine with a 90-mm extruder and longer stroke (685 mm). The dual-station model EBM 6.0-D-L/S will run two eight-cavity molds for 300-cc Boston round HDPE cosmetic containers on a 12-sec cycle, producing 4800 bottles/hr.

The latest wheel machine from Wilmington Machinery is the Series III, a large-platen unit with 30 stations and up to 60 cavities (with dual parisons). It combines six-layer coextrusion, energy-saving electromechanical clamp system, and improved bottle handling to boost throughput. Wilmington says mold changes are fast and simple and positioning of the molds to minimize flash and scrap is made effortless with the company’s “radial positioning” feature. The Series III is offered in sizes for single-serve juice and dairy containers and in larger models for 5L and 6L containers. Output can range from a few thousand to over 20,000 bottles/hr.

Another new wheel system comes from Urola S.C. of Spain, which just recently opened its first U.S. office. At K 2004, the company will introduce a 20-station wheel designed to compete with large rotary-machine makers like Graham Machinery and Wilmington, says Urola USA general manager Lou Maiero. Previously, Urola primarily served the European market with smaller rotary machines of up to 14 stations.

shuttle machine, the UMS 16D
Uniloy Milacron’s new shuttle machine, the UMS 16D, offers tiebarless accessiblilty to the mold area plus in-machine trimming and closed-loop position and speed control.

The new M20 rotary consists of two 10-station wheels with a common center plate and two extruders. The two streams of bottles pass through a common trimmer. Maiero says this side-by-side wheel design is the first on the market and costs less, uses less energy, and occupies less floor space than bigger competing wheel machines. It is targeted for HDPE containers for chemical, dairy, and food applications.

Versatile PET units
Although PET machinery was a major focus of new developments at the last K show, most suppliers did not release information on new models in advance of the show. An exception was SIPA of Italy, which claims to set a new standard for flexibility in PET bottle production with its SFR 9/27 rotary reheat machine. The unit’s nine blowing stations can mount three-cavity molds for single-serve bottles or single-cavity molds for family-size containers. The machine puts out 40,000 bottles/hr at 0.6 liters and 15,000/hr for a 3L size.

Also notable about the SFR 9/27 are its small footprint (one-half to one-third that of competing machines), its simple mechanical set-up, and a preform heating and stabilizing system that reportedly allows a wide processing window.

In addition, Automa of Italy will unveil a one-stage injection stretch-blow molder for wide-mouth PET containers. Model NSB 140 has a 140-ton injection clamp, up to 14 cavities, and an electric-powered injection unit. Dry-cycle time is said to be just 3 sec.

Injection-blow targets PET
At least two injection-blow molding exhibits will emphasize production of unoriented PET bottles. Novapax of Germany will show a new four-station machine for high production of PET containers. The NSB 850/400, with a 93-ton preform clamp, is said to compete with larger three-station machines by accommodating a 35.4-in. transfer head to run high-cavitation molds. It runs 60-cc wide-mouth tablet bottles in 17 cavities and 200-cc wide-mouth bottles in 12 cavities. The unit comes with a Siemens Siemotion touchscreen control system, a new rapid indexing unit, and an electric screw drive for precise plasticating control when handling sensitive resins. Novapax says the NSB 850 can also run existing molds for three-station injection-blow machines, requiring only additional core rods, interchange parts, and minor mold adjustments for fit.

Jomar Corp. is introducing two high-production injection-blow units. The M-40 model with 38-ton preform clamp will run a six-cavity mold at the show, producing 10-cc oval PET bottles for cosmetics or hotel amenities. The machine boasts a 10-sec cycle and produces 2160 bottles/hr. Jomar said many of its late-model injection-blow machines can be modified to produce small PET bottles up to 150 cc.

Jomar’s new M-85-S (72 tons) will be shown running a 10-cavity mold producing 100-cc HDPE pharmaceutical containers. The machine runs a 11.5-sec cycle, producing 3130 bottles/hr. It can run bottles from 5 cc to 1L.
