Apparatus for attaching sliders onto zipper bags and film
摘要:
A keeper (12), a clamp (14), a heater strip (16) and a heated air diffuser (18) are provided for a slider insertion apparatus (10) which inserts sliders (28) on the interlocked profiles (20, 22) of a zipper (23). The heater strip (16) and/or the diffuser (18) heat the zipper (23) to a predetermined temperature prior to slider insertion. The keeper (12) aligns the slider (32) within the insertion area (34) with the activator with pusher (26) of the slider insertion apparatus (10). By changing the mounting of the zipper guide (28) and by actuating the clamp (14) during slider insertion, the zipper (32) indexes to the slider insertion apparatus (10) in alternate directions.
