Machine for processing web of material
View Patent ↗The present invention relates to a process used for packaging a product in a web of material that has a zipper attached thereto. The process includes providing a web of material having first and second edges and a zipper including first and second interlocking members. The first and second interlocking members of the zipper are interlocked together. The first interlocking member of the zipper is attached to the web at an intermediate portion of the web between the first and second edges of the web. The second interlocking member has an attachment region that is facing away from the web. One edge of the web is folded away from the zipper and toward the other edge of the web. Unit operations are performed on the zipper to create zipper segments from the zipper while the zipper is exposed. Each of the zipper segments is associated with an individual food package made from the web.
1. A machine for processing a web of material that is used for a recloseable package, comprising:
a. a first station where a continuous zipper is attached to a web of material;
b. a second station downstream of said first station, said second station where said continuous zipper is oriented relative to said web of material for additional processing by moving a portion of said web of material away from said continuous zipper to expose said continuous zipper; and
c. a third station where said zipper is mechanically altered to form zipper segments and sliders are added to said zipper segments.
2. The machine of claim 1 , further including a fourth station where a pouch made from said web material is formed around said zipper.
3. The machine of claim 1 , wherein said third station includes a shuttle system for receiving said web and said attached zipper while said web and said attached zipper are in continuous movement and providing intermittent movement to said web and said attached zipper for forming said zipper segments.
4. The machine of claim 1 further including a fourth station and a fifth station, the fourth station being where a recloseable package made from said web material is formed around said zipper, the fifth station being where product is placed in said recloseable package.
5. The machine of claim 1 wherein said second station is a folding station that folds a short section of said web of material away from said zipper toward a long section of said zipper.
6. The machine of claim 1 wherein said third station includes a preseal station and notching station.
7. The machine of claim 6 wherein said third station further includes an end termination station.
8. A machine for making a recloseable package, comprising:
a. a first station where a continuous zipper is attached to a web of material;
b. a second station downstream of said first station, said second station where said continuous zipper is oriented relative to said web of material for additional processing by moving a portion of said web of material away from said continuous zipper to expose said continuous zipper; and
c. a third station where said zipper is mechanically altered to form zipper segments without mechanically altering said web.
9. The machine of claim 8 , further including a fourth station where a pouch made from said web material is formed around said zipper.
10. The machine of claim 8 , wherein said third station includes a shuttle system for receiving said web and said attached zipper while said web and said attached zipper are in continuous movement and providing intermittent movement to said web and said attached zipper for forming said zipper segments.
11. The machine of claim 8 , further including a fourth station and a fifth station, the fourth station being where a recloseable package made from said web material is formed around said zipper, the fifth station being where product is placed in said recloseable package.
12. The machine of claim 8 wherein said second station is a folding station that folds a short section of said web of material away from said zipper toward a long section of said zipper.
13. The machine of claim 8 wherein said third station includes a preseal station and notching station.
14. The machine of claim 13 wherein said third station further includes an end termination station.
