Abstract
A pile stripping comprising pile extending from a backing is described whereby the pile is made from pile yarns and the backing is bonded to the pile. A synthetic fiber is interlaced with the pile yarns, and the backing traps at least a part of the synthetic fiber in the backing. The stripping can further comprise a fin, whereby the fin can be located within the pile or alongside the pile. The backing and the fin may be constructed so that the backing is inserted in the fin.
Claims23
A method of forming a pile stripping, comprising:
- knitting a synthetic fibre into an end of pile yarns to hold the pile yarns together thereby forming a strip of pile, the strip of pile having sides and ends, the strip of pile having flat surfaces extending along part of the sides of the strip of pile at the knitted end,
- feeding the knitted end of the strip of pile into an extruder,
- forming a profiled backing by extruding a continuous length of thermoplastic elastomer, rubber, polymer or resin,
- concurrently allowing the thermoplastic elastomer, rubber, polymer or resin to flow in a plastic or molten state around the knitted end of the strip of pile, and
- bonding the knitted end of the strip of pile to the backing when the thermoplastic elastomer, rubber, polymer or resin solidifies trapping at least a part of the synthetic fibre.
2 more elements
A pile stripping, comprising:
- a synthetic fibre knitted into an end of pile yarns, wherein the strip of pile has sides and ends, the strip of pile having flat surfaces extending along part of the sides of the strip of pile at the knitted end;
- and
- a profiled backing extruded around the knitted end of the strip of pile, wherein the backing traps and bonds the knitted end of the strip of pile and at least a part of the synthetic fibre through solidification of a backing material, and wherein the backing material is a thermoplastic elastomer, rubber, polymer or resin.
