Abstract
Abstract A method for the injection molding of a laminate article having a deformable material sandwiched between a textile layer and a thermoplastic substrate and bonded into a unitary assembly by the thermoplastic. The laminate is molded into a sheet form for deformation to a preselected shape in a die-forming operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A process of injection molding for forming a flat deformable laminate having a thermoplastic substrate, as the bonding agent, said process comprising: (a) providing a thermoplastic resin and a deformable material wherein the memory recovery of the deformable material is less than the memory recovery of the thermoplastic resin; (b) providing a soft porous material; (c) lining a flat surface area of an injection mold cavity with said soft material; (d) placing the deformable material against said soft material; (e) closing said mold cavity with a second flat surface spaced from said deformable material to form a plastic receiving chamber means; (f) injecting the thermoplastic resin within said chamber means and about said deformable material and into said soft material; (g) allowing said thermoplastic resin to at least partially cool and harden; and then (h) removing the resultant flat deformable laminate from the cavity, said flat deformable laminate capable of further deformation into a preselected shape after removal from said cavity.
Claim 2
Dependent Claim
161 words
A process of injection molding for forming a flat deformable laminate having a thermoplastic substrate, as the bonding agent, said process comprising: (a) providing a thermoplastic resin and a deformable material wherein the memory recovery of the deformable material is less than the memory recovery of the thermoplastic resin; (b) providing a soft porous material; (c) lining a flat surface area of an injection mold cavity with said soft material; (d) placing the deformable material against said soft material; (e) closing said mold cavity with a second flat surface spaced from said deformable material to form a plastic receiving chamber means; (f) injecting the thermoplastic resin within said chamber means and about said deformable material and into said soft material; (g) allowing said thermoplastic resin to at least partially cool and harden; and then (h) removing the resultant flat deformable laminate from the cavity, said flat deformable laminate capable of further deformation into a preselected shape after removal from said cavity.
Claim 3
Dependent Claim
37 words
The process, according to claim 1, including the further step of forming the resultant laminate into said preselected shape, said preselected shape retained by the bonded securement of the substrate and porous material to the deformable material.
Claim 4
Dependent Claim
37 words
The process, according to claim 1, wherein the soft porous material is comprised of a fabric material having a pile surface, the pile surface of which is positioned against the first flat surface of the mold cavity.
Claim 5
Dependent Claim
28 words
The process, according to claim 1, wherein the deformable material is selected from the group consisting of a screen material, a wire rod material or a plastic material.
Claim 6
Dependent Claim
45 words
The process, according to claim 3, including the step of placing the resultant laminate in a forming die; and forming an article of a preselected shape conforming to the shape of a preselected surface for assembly thereon with the substrate surface adjacent the preselected surface.
