Method for manufacturing zippers

Abstract

The present invention discloses a method of manufacturing zippers, particularly a plurality of metal zipper teeth being sewed onto a zipper tape easily, and the zipper is comprised of a plurality of metal zipper teeth with clipping holes at their internal sides, each zipper teeth being clipped to a fastening string and colored (by paint roasting or electroplating) to a different color and then sewed onto the zipper tape. By the foregoing method, the present invention can solve the technical problems regarding the incorrect sewing direction of the zipper and poor pulling force as to extend the service life of the zipper.

1 . A method of manufacturing zippers, comprising the steps of: 
 (1) preparing a plurality of metal zipper teeth and a clipping end having through holes being disposed at one end of said zipper teeth;    (2) connecting and clipping said zipper teeth into a series, and a fixed end at one side of each zipper tooth being fixed onto a fastening string to form a series;    (3) coloring a zipper, and said connected series of zipper teeth being one selected from its original color and a different color produced by selectively paint roasting and electroplating; and    (4) sewing to a zipper tape, and said connected zipper teeth being sewed to said zipper tape quickly to produce a finished goods.    
   
   
       2 . The method of manufacturing zippers of  claim 1 , wherein said connected zipper tooth is of its original color.  
   
   
       3 . The method of manufacturing zippers of  claim 1 , wherein said zipper is colored by paint roasting and electroplating.  
   
   
       4 . The method of manufacturing zippers of  claim 1 , wherein said plastic steel zipper has its side being formed and coupled integrally with said fastening string.
