Abstract
Abstract Fastener attachment apparatus and method for separating a fastener attachment device comprising two end bars and a filament coupled therebetween from stock comprising two undivided and continuous side members and a plurality of cross links coupled therebetween and dispensing the devices through one or more slotted needles by pushing an end bar of the device through a slot in the needle. In addition there is disclosed a fastener attachment apparatus and method for simultaneously pushing each of the two end bars of a fastener attachment device through two slotted needles with the filament between the end bars extending through the slot of each of the needles and between the needles.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
199 words
A method of coupling two or more layers of material together which comprises inserting two needles of a fastener attachment device into the material with a portion of the needles extending above and below the layers of material, the needles having slots which are open, the steps of dividing plastic fastener attachment stock comprising two side members having a plurality of cross links coupled between said side members to provide a plastic fastener attachment device comprising a portion of each of said side members forming end bars and a cross link forming a filament, device having said end bars and said filament coupled between said end bars into the slot of said needles such that each end bar is positioned in a needle slot with the filament extending through the slot of each needle, then pushing said end bars through said needle slots while bending the filament with respect to said end bars as the end bars pass through the portion of the needles positioned within the material and the filament engages the material and then forcing said end bars out of said needles below the layers of material to permit them to twist with respect to the filament.
Claim 2
Independent Claim
199 words
A method of coupling two or more layers of material together which comprises inserting two needles of a fastener attachment device into the material with a portion of the needles extending above and below the layers of material, the needles having slots which are open, the steps of dividing plastic fastener attachment stock comprising two side members having a plurality of cross links coupled between said side members to provide a plastic fastener attachment device comprising a portion of each of said side members forming end bars and a cross link forming a filament, device having said end bars and said filament coupled between said end bars into the slot of said needles such that each end bar is positioned in a needle slot with the filament extending through the slot of each needle, then pushing said end bars through said needle slots while bending the filament with respect to said end bars as the end bars pass through the portion of the needles positioned within the material and the filament engages the material and then forcing said end bars out of said needles below the layers of material to permit them to twist with respect to the filament.
Claim 3
Dependent Claim

Claim 8
Independent Claim
63 words
A method of coupling layers of material together which comprises dividing fastener attachment stock comprising two plastic side members having a plurality of plastic cross links coupled between said side members to provide a fastener attachment device comprising a portion of each of said side members and a cross link and then inserting a portion of the fastener attachment device through the material.
Claim 9
Independent Claim
63 words
A method of coupling layers of material together which comprises dividing fastener attachment stock comprising two plastic side members having a plurality of plastic cross links coupled between said side members to provide a fastener attachment device comprising a portion of each of said side members and a cross link and then inserting a portion of the fastener attachment device through the material.
