Automatic application of zipper segment

Abstract

The disclosure relates to a method and apparatus for the application of zipper segments to opposite sides of a flat, form cut cardboard, paper or plastic card using double-sided adhesive tape. The card receives double-sided tape, and then zipper profiles are secured to the double-sided tape. Alternately, the zipper profiles and double-sided tape may be joined together and then applied to the card. The card is then folded and used for the packing of pieces of chewing gum or similar applications.

1 . A method of manufacturing a package, comprising the steps of:
 providing a sequence of cards;   applying a first strip of two-sided tape to the cards; and   applying a first zipper profile to the first strip of two-sided tape.   
     
     
         2 . The method of  claim 1  further comprising the step of applying a second strip of two-sided tape to the cards. 
     
     
         3 . The method of  claim 2  further comprising the step of applying a second zipper profile to the second strip of two-sided tape. 
     
     
         4 . The method of  claim 3  wherein the first strip of two-sided tape is applied to a first side of the cards and the second strip of two-sided tape is applied to a second side of the cards. 
     
     
         5 . The method of  claim 4  wherein the first strip of two-sided tape is parallel to the second strip of two-sided tape. 
     
     
         6 . The method of  claim 5  further including the step of removing backing paper from the first and second strips of two-sided tape prior to the steps of applying the first and second zipper profiles. 
     
     
         7 . The method of  claim 6  further including the step of folding the cards along a machine direction axis thereby bringing the first and second zipper profiles together. 
     
     
         8 . A method of manufacturing a package, comprising the steps of:
 providing a strip of stock material;   periodically applying a first strip of two-sided tape to the strip of stock material; and   periodically applying a first zipper profile to the first strip of two-sided tape.   
     
     
         9 . The method of  claim 8  further comprising the step of applying a second strip of two-sided tape to the strip of stock material. 
     
     
         10 . The method of  claim 9  further comprising the step of applying a second zipper profile to the second strip of two-sided tape. 
     
     
         11 . The method of  claim 10  wherein the first strip of two-sided tape is applied to a first side of the strip of stock material and the second strip of two-sided tape is applied to a second side of the strip of stock material. 
     
     
         12 . The method of  claim 11  wherein the first strip of two-sided tape is parallel to the second strip of two-sided tape. 
     
     
         13 . The method of  claim 12  further including the step of removing backing paper from the first and second strips of two-sided tape prior to the steps of applying the first and second zipper profiles. 
     
     
         14 . The method of  claim 13  further including the step of folding the strip of stock material along a machine direction axis thereby bringing the first and second zipper profiles together. 
     
     
         15 . A method of manufacturing a package, comprising the steps of:
 providing a sequence of cards;   applying a first zipper profile to a first strip of two-sided tape; and   applying the first strip of two-sided tape, with the first zipper profile attached thereto, to the cards.   
     
     
         16 . The method of  claim 15  further comprising the step of applying a second zipper profile to a second strip of two-sided tape. 
     
     
         17 . The method of  claim 16  further comprising the step of applying the second strip of two-sided tape, with the second zipper profile attached thereto, to the cards. 
     
     
         18 . The method of  claim 17  wherein the first strip of two-sided tape is applied to a first side of the cards and the second strip of two-sided tape is applied to a second side of the cards. 
     
     
         19 . The method of  claim 18  wherein the first strip of two-sided tape is parallel to the second strip of two-sided tape. 
     
     
         20 . The method of  claim 19  further including the step of providing a single reel from which the first and second zipper profiles are provided, initially interlocking with each other. 
     
     
         21 . A method of manufacturing a package, comprising the steps of:
 providing a stock material;   applying a first zipper profile to a first strip of two-sided tape;   applying the first strip of two-sided tape, with the first zipper profile attached thereto, to the stock material.   
     
     
         22 . The method of  claim 21  further comprising the step of applying a second zipper profiles to a second strip of two-sided tape. 
     
     
         23 . The method of  claim 22  further comprising the step of applying the second strip of two-sided tape, with the second zipper profile attached thereto, to the stock material. 
     
     
         24 . The method of  claim 23  wherein the first strip of two-sided tape is applied to a first side of the strip of stock material and the second strip of two-sided tape is applied to a second side of the strip of stock material. 
     
     
         25 . The method of  claim 24  wherein the first strip of two-sided tape is parallel to the second strip of two-sided tape.
