MODEL 34 Heated Handle Cut System
PARK AIR’s most adaptable Handle Cut System. This unit is designed for use with either sideweld or bottom seal bag machines (up to 5 across on a 60" width). The new heated blade makes it possible to cut cleaner looking handles in any polyethylene or polyethylene blend with greater blade life at greater speeds. The unit is able to slide across the bag machine and has a pneumatic locking frame system which holds it in place and allows for fast position changes.
The Heated Handle Cut System is an electrically activated, air powered unit. The unit is capable of accepting a virtually infinite variety of shapes and sizes. Speeds up to 250 cycles per minute on a production basis. Venturi vacuum system is used to remove slugs automatically. Cutters are made of spring steel, heat treated for longer wear and plated for smoother action.
Driven Longitudinal Drum Sealer - Model 88-Driven
Making a continuous seal on a moving web can be convenient in a number of types of applications. The Driven Longitudinal Drum Sealer Model 88-Driven is designed to address the need to produce a running seal between two separate layers of thin film, or when using multiple sealing heads across the drum surface. By creating the seal over a drum, tension differentials that may adversely affect seal strength and quality are eliminated. The drum acts as a large roller keeping both film layers flat and in correct orientation during the sealing process. Applications for the model 88 include document pockets on shipping envelopes and some of the more complicated diaper bags.
The Model 88 can be used for a number of other applications. These range from edge seal and trim to produce tubing from sheeting, slit sealing, and header sealing. The unit can be produced for multiple lanes and with a variety of sealing configurations. For slit sealing, we produce a 1/8” wide seal that is slit using a heated razor assembly.
There are two sealing head configurations available. Unique to the PARK AIR product line is the Hot Bar contacting seal head over the drum. The seal head is pressed against the drum contacting a Teflon® belt that is driven by the film. This unit produces a high integrity seal at high speeds.
The second sealing configuration is Hot Air. This is a non-contacting sealing head using a unique approach to direct a stream of heated air onto the material. This unit is also driven by the web motion. With the Hot Air configuration, there is no pressure on the seal. This configuration is recommended for high density films. Both configurations can be supplied with a heated razor blade for slit sealing application. The blade holder includes a micro adjustment screw for accurate positioning.
The units are supplied complete and ready to position in-line. Installation requires electric power and compressed air. Each seal head is independently controlled and is complete with heaters, thermocouple, and all connections. The unit is pneumatically engaged upon film start and disengaged when the film stops. Various width seals can be quoted on request.
For light gauge films or multi-head operation, Park Air now offers an optional driven drum design. This motor driven drum is synchronized to the incoming web speed by way of an encoder. Driving the drum reduces stress on the film and seals insuring high quality sealed edges.
Roller Sealer - HRS – 5000
The HRS-5000 ROLLER SEALER produces a header seal on a moving web. The unit is positioned on the floor between the “V” Board and the Capstan. It needs no mounts and is installed in minutes. The unit can be tilted in any direction to meet the oncoming web and can be moved in and out to position the seal relative to the fold of the bag.
Material is fed through unit which has rollers on either end holding an endless Teflon® belt in a taut condition, for no slippage of web. Upper and lower sealing jaws are centered in a closed condition with a known temperature and air pressure. On this unit, dwell is in relation to web speed. Temperature is regulated by a controller, and air pressure is controlled by a regulator. The unit has a heat sink section with fan to cool the seal.
PARK AIR can also offer the Roller Sealer with a “Third Belt Assembly.” This assembly will allow production of fold over handle top bags and other types of bags requiring separation of sealed layers. The standard unit has a 6" throat depth.
Zero Clearance Punch and Die - Model 16
Different materials have varying cutting requirements. Whereas polyethylene films can be efficiently cut with serrated edged tools, laminates, coextrusions and polypropylenes have other requirements. For high quality fine print pouches and bags, ragged looking hole cutouts are not acceptable.
Park Air has developed a special cutting system for these difficult to work with materials. The Model 16 features a fitted punch and die in an integrated unit assembly to accomplish precision alignment to tolerances below .001”. This punch creates a scissors action resulting in totally clean edges around the hole cutout. In polypropylene these clean edges prevent fracturing. In laminates and coextrusions, this clean appearance does not detract from the overall product appearance.
The Model 16 is easily adaptable to any bag or pouch making machine. Cycle rates up to 200 per
minute depending on hole shape and size and material to be cut.
These units are available for any of the standard hanger hole, tear notch or handle shapes. We can
also do round holes, thumb notches and made to order shapes and sizes. Economically priced, the
Model 16 represents an alternative to the costly expense of repair and replacement for current poorly
designed or worn out units. The punch and die can be field serviced and are easily sharpened for extra long life.
