Abstract
Abstract An article having a slide fastener closure and formed of sheet material secured to a slide fastener to define flaps extending over the slide fastener and meeting at a center line aligned with interengaging elements of the slide fastener, the sheet material either being separated along the center line or having a scored tear line therealong to facilitate separating. A method of installing the slide fastener includes moving a deforming member to engage the sheet material, which is positioned over the slide fastener, and force the sheet material and the slide fastener against an anvil, the deforming member carrying spaced sealing protrusions securing the sheet material to the tape of the slide fastener and a centrally disposed scoring protrusion forming the scored tear line. Apparatus for installing the slide fastener includes the anvil, which has an elongate recess therein for positioning the slide fastener, and the deforming member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
A method of installing a slide fastener on sheet material comprising the steps of positioning the slide fastener and the sheet material between an anvil and a deforming member carrying spaced sealing protrusions and a scoring protrusion centrally disposed between the spaced sealing protrusions, moving the deforming member relative to the anvil to engage the sheet material and compress the sheet material and the slide fastener between the anvil and the deforming member, and securing the slide fastener to the sheet material between the anvil and the sealing protrusions of the deforming member as the sealing protrusions engage the sheet material during the moving of the deforming member relative to the anvil while at the same time forming a tear line along the sheet material between the sealing protrusions of the deforming member as the scoring protrusion of the deforming member engages the sheet material during the moving of the deforming member relative to the anvil.
Claim 2
Independent Claim
156 words
A method of installing a slide fastener on sheet material comprising the steps of positioning the slide fastener and the sheet material between an anvil and a deforming member carrying spaced sealing protrusions and a scoring protrusion centrally disposed between the spaced sealing protrusions, moving the deforming member relative to the anvil to engage the sheet material and compress the sheet material and the slide fastener between the anvil and the deforming member, and securing the slide fastener to the sheet material between the anvil and the sealing protrusions of the deforming member as the sealing protrusions engage the sheet material during the moving of the deforming member relative to the anvil while at the same time forming a tear line along the sheet material between the sealing protrusions of the deforming member as the scoring protrusion of the deforming member engages the sheet material during the moving of the deforming member relative to the anvil.
Claim 3
Dependent Claim
50 words
A method of installing a slide fastener as claimed in claim 1 wherein the sheet material is a heat bondable type and said step of moving the deforming member includes applying heat to the sheet material from the deforming member to heat bond the slide fastener to the sheet material.
Claim 4
Dependent Claim
59 words
A method of installing a slide fastener as claimed in claim 1 wherein said positioning step includes positioning a liner strip of heat bondable material on a side of the slide fastener opposite the sheet material, and wherein siad step of moving the deforming member includes heat bonding the liner strip and the slide fastener to the sheet material.
Claim 5
Dependent Claim
41 words
A method of installing a slide fastener as claimed in claim 1 and further comprising the step of applying a force to move the sheet material away from the slide fastener and break the sheet material open along the tear line.
Claim 6
Dependent Claim
33 words
A method of installing a slide fastener as claimed in claim 3 and further comprising the steps of stitching the liner stRip around the slide fastener and slitting the liner strip during stitching.
Claim 7
Dependent Claim
26 words
A method of installing a slide fastener as claimed in claim 1 and furhter comprising the step of separating the sheet material along the tear line.
Claim 8
Dependent Claim
40 words
A method of installing a slide fastener as claimed in claim 6 wherein said separating step includes applying a force to move the sheet material away from the slide fastener and break the sheet material open along the tear line.
Claim 9
Dependent Claim
57 words
A method of installing a slide fastener as claimed in claim 6 wherein the slide fastener includes a slider and wherein said separating step includes moving the slider to open the slide fastener and apply a force to move the sheet material away from the slide fastener and break open the sheet material along the tear line.
Claim 10
Dependent Claim
59 words
A method of installing a slide fastener as claimed in claim 6 wherein said positioning step includes positioning a liner strip of heat bondable material on a side of the slide fastener opposite the sheet material, and wherein said step of moving the deforming member includes heat bonding the liner strip and the slide fastener to the sheet material.
