Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
177 words
The method of making fastener elements for use with apparel comprising feeding forward a continuous base strip of material which is heat-sealable at least on one surface thereof, feeding forward a continuous fastener tape constituting one of a hook tape or a plush tape adapted to be releasably fastened together by pressing them together, said fastener tape being heat sealable to the base strip, combining the fastener tape with the base strip as they are fed forward with the fastener tape extending longitudinally of the base strip on said surface of the latter, heat-sealing the fastener tape to the base strip on relatively narrow seals extending longitudinally of the fastener tape spaced transversely of the fastener strip, and segmenting the combined base strip and fastener tape on transverse lines at intervals spaced longitudinally thereof to form individual fastener elements each comprising a band of the base material having a segment of fastener tape material heat-sealed on one surface of the band by relatively narrow seals extending across the element from one side edge thereof to the other.
Claim 2
Independent Claim
177 words
The method of making fastener elements for use with apparel comprising feeding forward a continuous base strip of material which is heat-sealable at least on one surface thereof, feeding forward a continuous fastener tape constituting one of a hook tape or a plush tape adapted to be releasably fastened together by pressing them together, said fastener tape being heat sealable to the base strip, combining the fastener tape with the base strip as they are fed forward with the fastener tape extending longitudinally of the base strip on said surface of the latter, heat-sealing the fastener tape to the base strip on relatively narrow seals extending longitudinally of the fastener tape spaced transversely of the fastener strip, and segmenting the combined base strip and fastener tape on transverse lines at intervals spaced longitudinally thereof to form individual fastener elements each comprising a band of the base material having a segment of fastener tape material heat-sealed on one surface of the band by relatively narrow seals extending across the element from one side edge thereof to the other.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein the fastener tape is a hook tape.
Claim 4
Dependent Claim
13 words
The method of claim 1 wherein the fastener tape is a plush tape.
Claim 5
Dependent Claim
45 words
The method of claim 1 wherein the continuous base strip is relatively wide and both a hook tape and a plush tape are sealed to the base strip, one adjacent one side edge and the other adjacent the other side edge of the base strip.
Claim 6
Dependent Claim
93 words
The method of claim 1 for making bra back fastener elements wherein the base strip is a two-ply strip with the plies free of one another at least at one side edge thereof, the tape being sealed to the outer surface of one of said plies spaced inwardly from said side edge and the sealing securing the plies together, each element segmented from the combined strip and tape having free margins of the strip material at said edge adapting it for being stitched to part of a bra sandwiched between said free margins.
Claim 7
Dependent Claim
37 words
The method of claim 5 wherein the base strip is folded on a line extending longitudinally thereof to have said two plies, with the plies integrally joined along said fold line at the other side edge thereof.
Claim 8
Dependent Claim
35 words
The method of claim 5 wherein the tape is a hook tape narrower than the strip and is sealed to the strip on only two lines of seal extending longitudinally thereof adjacent its side edges.
Claim 9
Dependent Claim
37 words
The method of claim 5 wherein the tape is a relatively wide plush tape and is sealed to the strip on at least three lines of seal extending longitudinally thereof forming at least two side-by-side plush zones.
Claim 10
Dependent Claim
161 words
The method of claim 1 for making shoulder strap guards wherein the base strip is heat-sealable on both surfaces, is folded over on a fold line adjacent one side to have a relatively narrow margin in face-to-face relation with the strip, wherein a hook tape and a plush tape are fed forward and combined with the base strip, one overlapping the edge of said margin and the other adjacent the opposite side of the strip, each tape being heat-sealed to the strip on relatively narrow seals extending longitudinally of the tapes adjacent the edges of the tapes, one of these seals securing the margin, and segmenting the combined base strip and tapes on transverse lines spaced longitudinally thereof to form individual shoulder guards each comprising a band of base material having a loop for a safety pin at one end formed by said margin and having hook and plush segments adjacent its ends for fastening the band around a shoulder strap.
