Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
171 words
In a threadless slide fastener chain, the combination comprising a carrier tape, a filamentary stringer having a plurality of head elements and a plurality of generally U-shaped heel members with leg portions interconnecting the plurality of head elements, said filamentary stringer being disposed along a longitudinal edge of said carrier tape with a first set of the plurality of heel members on one side of the carrier tape and with a second set of the plurality of heel members on the other side of the carrier tape, said filamentary stringer having first intErstices between the leg portions of the first set of heel members and having second interstices between the leg portions of the second set of heel members, said carrier tape adjacent the longitudinal edge being sinuous to form portions of the carrier tape projecting into the first interstices, and said first and second sets of heel members being threadlessly bonded with said carrier tape such that the projecting portions of the carrier tape are retained in the first interstices.
Claim 2
Dependent Claim
171 words
In a threadless slide fastener chain, the combination comprising a carrier tape, a filamentary stringer having a plurality of head elements and a plurality of generally U-shaped heel members with leg portions interconnecting the plurality of head elements, said filamentary stringer being disposed along a longitudinal edge of said carrier tape with a first set of the plurality of heel members on one side of the carrier tape and with a second set of the plurality of heel members on the other side of the carrier tape, said filamentary stringer having first intErstices between the leg portions of the first set of heel members and having second interstices between the leg portions of the second set of heel members, said carrier tape adjacent the longitudinal edge being sinuous to form portions of the carrier tape projecting into the first interstices, and said first and second sets of heel members being threadlessly bonded with said carrier tape such that the projecting portions of the carrier tape are retained in the first interstices.
Claim 3
Dependent Claim
17 words
The invention as recited in claim 1 wherein said carrier tape comprises a material containing thermoplastic fibers.
Claim 4
Dependent Claim
12 words
The invention as recited in claim 2 wherein said material is woven.
Claim 5
Dependent Claim
12 words
The invention as recited in claim 2 wherein said material is nonwoven.
Claim 6
Dependent Claim
31 words
The invention as recited in claim 2 wherein said filamentary stringer comprises a thermoplastic material, and wherein said first and second sets of heel members are fused with said carrier tape.
Claim 7
Dependent Claim
23 words
The invention as recited in claim 1 wherein said carrier tape is initially formed flat and subsequently deformed to assume its sinuous shape.
Claim 8
Dependent Claim
21 words
The invention as recited in claim 1 wherein said carrier tape is initially formed with one edge having its sinuous shape.
Claim 9
Dependent Claim
27 words
The invention as recited in claim 1 wherein said first and second sets of heel members are rigidly bonded to the projecting portions of said carrier tape.
Claim 10
Dependent Claim
45 words
The invention as recited in claim 6 wherein said filamentary stringer comprises a thermoplastic material and said carrier tape comprises a material containing thermoplastic fibers, and wherein said first and second sets of heel members are fused to the projecting portions of said carrier tape.
Claim 11
Dependent Claim
31 words
The invention as recited in claim 1 wherein the ends of adjacent heel members on the one and other sides of the carrier tape are bonded together through said carrier tape.
Claim 12
Dependent Claim
36 words
The invention as recited in claim 10 wherein said filamentary stringer comprises a thermoplastic material, and wherein the ends of adjacent heel members on the one and other sides of the carrier tape are fused together.
Claim 13
Dependent Claim
42 words
The invention as recited in claim 11 wherein said carrier tape comprises a material containing thermoplastic fibers, and wherein the ends of adjacent heel members on the one and other sides of the carrier tape are fused together by said carrier tape.
Claim 14
Dependent Claim
53 words
The invention as recited in claim 1 wherein said carrier tape defines a plurality of spaced holes therethough longitudinally aligned in parallel relationship with said longitudinal edge of said carrier tape, each of said holes being interposed between ends of adjacent heel members on the one and other sides of the carrier tape.
Claim 15
Dependent Claim
21 words
The invention as recited in claim 13 wherein the ends of said adjacent heel members are bonded together through said holes.
Claim 16
Dependent Claim
29 words
The invention as recited in claim 14 wherein said filamentary stringer comprises a thermoplastic material and wherein ends of said adjacent heel members are fused together through said holes.
Claim 17
Dependent Claim
36 words
The invention as recited in claim 1 wherein said carrier tape adjacent the longitudinal edge is sinuous to form portions of the carrier tape projecting in opposite directions and into the respective first and second interstices.
Claim 18
Dependent Claim
58 words
The invention as recited in claim 1 wherein said carrier tape adjacent the longitudinal edge has first and second portions projecting into respective spaced first interstices and spaced second interstices, and said filamentary stringer having interposed first interstices and interposed second interstices between the respective spaced first and second interstices free of projecting portions of the carrier tape.
Claim 19
Dependent Claim
178 words
In a threadless slide fastener chain, the combination comprising a carrier tape, a filamentary stringer having a plurality of head elements and a plurality of generally U-shaped heel members with leg portions interconnecting the plurality of head elements, said filamentary stringer being disposed along a longitudinal eDge of the carrier tape with a first set of the plurality of heel members on one side of the carrier tape and with a second set of the plurality of heel members on the other side of the carrier tape, said filamentary stringer having first interstices between the leg portions of the first set of heel members and having second interstices between the leg portions of the second set of heel members, said carrier tape adjacent the longitudinal edge having portions projecting into spaced first interstices with interposed first interstices between the spaced first interstices free of projecting portions of the carrier tape, and said first and second sets of heel members being threadlessly bonded with the carrier tape such that the projecting portions are retained in the spaced first interstices.
Claim 20
Dependent Claim
178 words
In a threadless slide fastener chain, the combination comprising a carrier tape, a filamentary stringer having a plurality of head elements and a plurality of generally U-shaped heel members with leg portions interconnecting the plurality of head elements, said filamentary stringer being disposed along a longitudinal eDge of the carrier tape with a first set of the plurality of heel members on one side of the carrier tape and with a second set of the plurality of heel members on the other side of the carrier tape, said filamentary stringer having first interstices between the leg portions of the first set of heel members and having second interstices between the leg portions of the second set of heel members, said carrier tape adjacent the longitudinal edge having portions projecting into spaced first interstices with interposed first interstices between the spaced first interstices free of projecting portions of the carrier tape, and said first and second sets of heel members being threadlessly bonded with the carrier tape such that the projecting portions are retained in the spaced first interstices.
