Abstract
A method of manufacturing footwear, including the steps of positioning a sock portion over a mold element in which the sock portion comprises a fabric layer and a thermoplastic film layer connected to the fabric layer, such that the thermoplastic film layer is positioned between the mould element and the fabric layer, and injection-molding a thermoplastic material to the sock portion positioned over the mold element such that heated thermoplastic material flows through the fabric layer and bonds with the thermoplastic film layer and such that the thermoplastic material at least partially covers the fabric layer for forming a portion of an item of footwear.
Claims12
A method of manufacturing footwear, comprising the steps of:
- positioning a sock portion over a mold element in which said sock portion comprises a fabric layer and a thermoplastic film layer connected to the fabric layer, such that the thermoplastic film layer is positioned between the mould element and the fabric layer;
- and
- injection-molding a thermoplastic material to said sock portion positioned over the mold element such that heated thermoplastic material flows through the fabric layer and coheres with the thermoplastic film layer and such that the thermoplastic material at least partially covers the fabric layer for forming a portion of an item of footwear.
An item of footwear which is manufactured according to a process comprising the steps of:
- positioning a sock portion over a mold element in which said sock portion comprises a fabric layer and a thermoplastic film layer connected to the fabric layer, such that the thermoplastic film layer is positioned between the mould element and the fabric layer;
- and
- injection-molding a thermoplastic material to said sock portion positioned over the mold element such that heated thermoplastic material flows through the fabric layer and bonds with the thermoplastic film layer;
- wherein the item of footwear includes a portion formed by said sock portion and a layer of thermoplastics material which at least partially covers the fabric layer of said sock portion;
- and
- wherein said portion of the item of footwear includes a cohered thermoplastics material portion formed of portions of said thermoplastic material and said thermoplastic film layer.
