Abstract
The zippers include flanges with fully or partially formed apertures or notches to allow drive rolls to positively engage and feed the zippers. Alternatively, a T-shaped guide rail can be formed on at least one flange to allow drive rolls to engage the zipper. These aspects are particularly adaptable to feeding a zipper or zipper segment to a transverse direction zipper applicator.
Description
- 1. Field of the Invention
- The present invention relates to a method for producing perforated zipper for positive and improved feeding and tracking of the zipper through a transverse direction zipper applicator, particularly in the art of producing reclosable packaging.
- 2. Description of the Prior Art
- In the prior art of reclosable packaging and the methods of manufacture thereof, including form fill and seal (FFS) and related methods, it is well-known to provide and apply the reclosable zipper in a direction which is transverse to the direction of movement of the film (i.e., the machine direction). While these methods are well-developed and suitable for their intended purposes, further improvements are sought in the reliability of the tracking and placement of the zipper into the final position where it is sealed to the film, particularly when production rates and speeds are increased.
- In particular, nip roll systems typically include one or more sets of smooth or patterned rolls. However, these systems may have difficulty in consistently pushing a soft zipper to the final desired position prior to sealing to the film. Similarly, due to the asymmetrical nature of some zipper profiles, zippers that travel through the nips may become skewed and lose their tracking. Similarly, the zipper may need to be supported between or after a set of nips. This is typically done with rollers, which may further contribute to the skewed tracking of the zipper.
- Similarly, grip and pull drive systems use a chain drive or a servo driven clamp system to place the zippers. While these systems are well-developed and suitable for their intended purposes, the zipper may have to be released and recaptured from the drive system in order to perform necessary options such as end crushing or cutting. This may become less reliable at higher production rates. Similarly, if a zipper segment that is ready to be sealed to the film is gripped by a clamp, the clamping assembly may obstruct the zipper-to-film sealing process.
- It is therefore an object of the present invention to provide a method for the transverse placement of zippers on a moving film, particularly in the production of reclosable packages wherein the reliability of the tracking and placement of the zipper are improved, thereby leading to the possibility of higher production rates.
- This and other objects are attained by providing a zipper with perforated or punched flanges that will allow the feeding apparatus to feed and drive the zipper positively to a transverse direction (TD) zipper application device, which places the zipper onto a film perpendicular to the direction of film travel.
- Alternatively, a textured surface is provided on the portion of the zipper flanges that face the driving rollers in the transverse direction drive train. The texturing allows the zipper drive rollers or belts to positively engage and move the zipper forward. The texturing can be rough surface which is engaged by gnurled drive rolls, or can be a shape extruded into the zipper flange that allows the drive rollers or belts to grab the zipper.
- Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:
