Park Air Converting Equipment offers two styles of Zippers which sealing technologies have been pioneered over many years. Our vertical Zipper is a turnkey unit for the application of “string or flanged” zipper profile designed to work with a wide variety of zippers and bag materials. Our Horizontal Zipper is designed for laminated and coextruded materials which at one time presented difficulties for converters. Park Air's new line includes Intermittent Sealing for the Slider Applicator.
Zipper Attachment - Model Z - 4900
Using fundamental sealing technologies pioneered by PARK AIR over the last twenty years, the company offers a turnkey unit for the application of “string or flanged” zipper profile. Designed to work with a wide variety of zippers and bag materials, the unit is able to out produce the more costly competition. Using basic sealing techniques and web controls, zipper application has never been easier or more cost effective.
The unit is able to be set up for applying zipper in either the open or closed end of the bag. This equipment can be supplied for multi-lane operation. A special unit adaptation for inserting the zipper horizontally is ideal for use in pouch making applications. The unit is easily placed in-line with any bag maker. The compact framework requires only five feet of space between the “V” board and the capstan roll. All controls are at a convenient height for the operators.
The patented unit design has also been applied to form fill and seal for applying profile in packaging applications. Incorporating material unwinds, drives and folding boards, the unit is completely self-contained.
SERRATORS
Park Air Serrating systems are designed for both on the edge serrations as well as multi lanes serrations for easy or hard tears. Park Air also offers a cross bank serrator unit for perforated sleeves on a roll which are required to have a known tear for proper pull separation.
Multiple Serrator
A versatile tool developed for slitting or serrating, the RS-1900 is available in a variety of configurations. For sideweld application of an "easy open" serration, the unit is available with standard throat depths of 2-1/8" or 4-1/8". Serration wheels are standard 12 and 24 tooth for easy and hard pull. Special tooth configurations or slitting wheels can be quoted on request.
For serration in the middle of wide webs or for multiple serrations in the machine direction, this unit is now available in a split configuration. The upper section supports the air activated serrating assembly. The lower section supports the bearing block and holder or hardened roller shaft. The unit features larger diameter wheels for longer life. This unit can also be supplied with multiple heads.
Rotary Serrator
A versatile tool developed for slitting or serrating, the RS-1900 is available in a variety of configurations.
Cross Bank Serrator
This is an air-operated, electrically activated unit that will mount and operate on any Intermittent Motion Machine from 12" to 60" wide. It features instant installation and minimum maintenance.
Designed to have a known spacing between individual “razor type” blades. With the adjustable depth penetration feature, a proper tear factor for any width of web and any thickness of film is easily obtained.
The new area of perforated sleeves on a roll must have a known tear for proper pull separation. Each
blade is heat treated for maximum hardness and instantly replaceable; no replacing a whole serrating bar for one broken “tooth”.
This unit uses the principle of holding the material taut while it is being cut, for straightness of cut and repetitious spacing. The blades go into a cavity that is filled, so that the film is not crimped or
distorted in any manner.
FEATURES / BENEFITS
• From 12" to 60" widths
• Up to 150 cycles per minute
• Mounts available for all intermittent bag machines
• Individual heat-treated, razor-type blade
• Center cut blades
• Air operated/electrically activated
