1481224 Pile fabrics METZELER SCHAUM GmbH 21 Aug 1974 [21 Aug 1973 26 July 1974] 36803/74 Heading D1K A method of making a pile fabric wherein molten polymer is separated from a heated surface to draw fibrils from the polymer is characterised by allowing some of the polymer to remain adhered to the surface to as a continuous film with a thickness of at least 10 microns. A backing 19 and polymer 18 are fed to a heated roll 10 and separated from the roll over a cooling nozzle 14. Angles of separation 30 and inclination of nozzles 27 are given. The nozzle 14 may discharge gas, vapour, liquid, entrained solids or mixtures thereof. The film 20 remaining on the roll 10 is shrouded from the atmosphere by inert gas in a shroud 21. By using different polymers a laminate may be built up on the roll 10 producing pile having a mixture of polymers. Details of suitable polymers are given. The roll 10 may be replaced by a continuous belt (Figure 3, not shown).
