ABSTRACT:
A method and an apparatus for automatically feeding zipper assemblies (with or without sliders) to a station, for example, a station where the zipper assemblies are sealed to thermoplastic bag making film. The zipper tape feeding apparatus comprises a pair of endless belts that circulate in opposite directions and have confronting portions running along a straight pathway through which a zipper tape is passed. The first belt is driven intermittently by a motor and the second belt is free to circulate during frictional contact with the first belt. At least a portion of the zipper tape is sandwiched between confronting portions of the belts, being moved forward as the belts circulate. The belts are preferably made of rubber to minimize slippage of the zipper tape during feeding.
