Abstract:
1. 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.
