Abstract
A method of extruding a continuous profiled fastener onto a thermoplastic film substrate, and more particularly, a method for the continuous bonding of a profiled fastener assembly to a thermoplastic cuff film substrate through the intermediary of hot extrusion.
Claims3
A method for the continuous bonding of a hot-extruded profiled fastener assembly to a thermoplastic film substrate;
- comprising advancing a continuous web of said film substrate over a metal bar having a generally curvilinear surface configuration;
- concurrently hot-extruding a continuous web of a profiled fastener element constituted from a thermoplastic polymer;
- contacting said profiled fastener element with said film substrate while said fastener element is in a substantially molten state so as to cause said fastener element to hot-fuse with the contacting surface of said film substrate;
- and immersing said fused contacting fastener element and film substrate into a cooling water bath.
