Abstract

1,013,382. Films. TOYO RAYON KABUSHIKI KAISHA. Dec. 21, 1961 [Dec. 28, 1960], No. 45956/61. Heading B5B. A film of synthetic thermoplastic polymer is heated by means of a radiant heat source and that portion of the film in the region of the heat source is stretched longitudinally while the transverse dimension of the film is maintained substantially constant, stretch-localizing means comprising a rod, roller or edge member being disposed transverse the longitudinal axis of the film. Apparatus as shown comprises feed rolls 1, 2, 3, draw rolls 8, 9, 10, idler rollers 4, 5, 7, edge 6 and radiant heater 11. In place of the edge 6 a rotatable roller or cylinder may be used. Films of polyamides, polyesters, polyolefins, polyacetals, polyvinyl chloride and polyvinylidene chloride may be stretched as described.
