Abstract
1377011 Fibrillatable films NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 21 Sept 1972 [22 Sept 1971] 43759/72 Heading B5B Fibrillatable films, preferably composed of polyethylene terephthalate, are produced by longitudinally stretching a film between roller pairs 2, 3 and 9, 10. The stretch print is localized by the edge 7 of heated prism 8 placed between the roller pairs. The film is given a second stretching by means of roller pair 13, 14, being heated in this second stage by means of heated, curved sheet 12. The prism 8 is preferably aligned so that face 16 which follows edge 7 is at an acute angle to the film; the alignment mast, however, be such that the first point of contact between the prism and the film is the edge 7. Preferably the first stretching is at a higher ratio, such as 1 : 4, than the second, which is for instance 1 : 1À5.
