Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
102 words
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.
Claim 2
Independent Claim
102 words
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.
Claim 3
Dependent Claim
14 words
Method as claimed in claim 1, wherein said film substrate comprises a cuff film.
Claim 4
Dependent Claim
53 words
Method as claimed in claim 1, comprising regulating the distance between the extrusion and the point of contact of said fastener element with said film substrate, and the distance from said point of contact with the water bath so as to optimize the hot-bonding between said fastener element and said thermoplastic film substrate.
