Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 149 words
A method for making a fastener subassembly comprised of a fibrous strip member and a unitary fastener element extending in part through said strip member and secured thereto, comprising the steps of: (a) arranging first and second dies, each defining a mold cavity, in opposed clamping relation to a non-apertured fibrous strip member; (b) supplying successively into one of said dies solidified and fluid molding material under pressure sufficient both to force said solidified material through said strip member to thereby rupture said strip member and define a passage in said strip member extending between the mold cavities and to force said fluid molding material into said passage and into each said mold cavity to fill said passage and each said mold cavity with said fluid molding material; (c) solidifying molding material in said passage and in each said cavity; and (d) separating said dies from said strip member.
Claim 2
Independent Claim 149 words
A method for making a fastener subassembly comprised of a fibrous strip member and a unitary fastener element extending in part through said strip member and secured thereto, comprising the steps of: (a) arranging first and second dies, each defining a mold cavity, in opposed clamping relation to a non-apertured fibrous strip member; (b) supplying successively into one of said dies solidified and fluid molding material under pressure sufficient both to force said solidified material through said strip member to thereby rupture said strip member and define a passage in said strip member extending between the mold cavities and to force said fluid molding material into said passage and into each said mold cavity to fill said passage and each said mold cavity with said fluid molding material; (c) solidifying molding material in said passage and in each said cavity; and (d) separating said dies from said strip member.
Claim 3
Dependent Claim 12 words
The fastener subassembly provided by practicing the method claimed in claim 1.
Claim 4
Independent Claim 141 words
A method for making a fastener subassembly comprised of a fibrous strip member and a unitary fastener element extending in part through said strip member and secured thereto, comprising the steps of: (a) arranging first and second dies, each defining a mold cavity, in opposed clamping relation to a non-apertured fibrous strip member; (b) solidifying a mass of fluid molding material; (c) applying a pressurized stream of fluid molding material to such solidified mass to force said mass into said first die mold cavity and onto said strip member to rupture said strip member and provide a passage in said strip member extending between the mold cavities; (d) further filling said passage and each said mold cavity with fluid molding material; (e) solidifying said molding material in said passage and each said cavity; and (f) separating said dies from said strip.
Claim 5
Independent Claim 141 words
A method for making a fastener subassembly comprised of a fibrous strip member and a unitary fastener element extending in part through said strip member and secured thereto, comprising the steps of: (a) arranging first and second dies, each defining a mold cavity, in opposed clamping relation to a non-apertured fibrous strip member; (b) solidifying a mass of fluid molding material; (c) applying a pressurized stream of fluid molding material to such solidified mass to force said mass into said first die mold cavity and onto said strip member to rupture said strip member and provide a passage in said strip member extending between the mold cavities; (d) further filling said passage and each said mold cavity with fluid molding material; (e) solidifying said molding material in said passage and each said cavity; and (f) separating said dies from said strip.
Claim 6
Dependent Claim 12 words
The fastener subassembly provided by practicing the method claimed in claim 3.
Claim 7
Independent Claim 168 words
A method for making a fastener subassembly comprised of a fibrous strip member and a unitary fastener element extending in part through said strip member and secured thereto, comprising the steps of: (a) arranging first and second dies, each defining a mold cavity, in opposed clamping relation to a non-apertured fibrous strip member, said first die having a port for receiving molding material; (b) supplying fluid molding material to an injection head having a port for issuing molding material; (c) cooling said injection head to solidify molding material therein; (d) placing said material issuing port in communication with said material receiving port and applying a pressurized stream of fluid molding material to said injection head thereby propelling the solidified molding material therein into said first mold cavity and through said strip by rupture thereof and into said second mold cavity and further filling said mold cavities with fluid molding material; (e) solidifying said fluid molding material in said mold cavities; and (f) separating said dies from said strip.
Claim 8
Independent Claim 168 words
A method for making a fastener subassembly comprised of a fibrous strip member and a unitary fastener element extending in part through said strip member and secured thereto, comprising the steps of: (a) arranging first and second dies, each defining a mold cavity, in opposed clamping relation to a non-apertured fibrous strip member, said first die having a port for receiving molding material; (b) supplying fluid molding material to an injection head having a port for issuing molding material; (c) cooling said injection head to solidify molding material therein; (d) placing said material issuing port in communication with said material receiving port and applying a pressurized stream of fluid molding material to said injection head thereby propelling the solidified molding material therein into said first mold cavity and through said strip by rupture thereof and into said second mold cavity and further filling said mold cavities with fluid molding material; (e) solidifying said fluid molding material in said mold cavities; and (f) separating said dies from said strip.
Claim 9
Dependent Claim 12 words
The fastener subassembly provided by practicing the method claimed in claim 5.
