Title: Improvements in the fibrillation of tape yarns
Inventor: BENYON JOHN
IPC: D01D5/42
Filed: 1969-10-16
Abstract: 1277933 Forming yarns TMM (RESEARCH) Ltd 25 Nov 1970 [16 Oct 1969] 50906/69 Heading D1F In a continuous method of fibrillating running tape yarn by the action of an air-jet device, the fibrillated tape passing from such device encounters tension reducing means whereby the tension in the tape during fibrillation is less than the tension in the tape at take-up. As shown in Fig. 1, tape 10 from a supply roll 11 is molecularly oriented by hotstretching in the zone between feed and draw rolls 13, 14, and 15, 16, then passes through an air jet device 18. Fibrillated tape passes in a succession of loops around stationary snubbing pins 19, 20, which absorb tension produced therein by winding the yarn onto a bobbin 22 by a ring 24 and traveller 23 takeup. In the apparatus of Fig. 2, tape 110 from a roll 111 is hot-stretched between feed godets 113, 114, and draw godets 115, 116, prior to entering an air-jet device 118. Fibrillated tape emerging from the device describes a long loop which is supported by the air stream from the device 118 before passing in a succession of loops around snubbing pins 119, 120, and taken-up onto a bobbin 126 on a winding head 127. Optimum fibrillation occurs when tape passing through device 118 is slack and to this end, before commencement of a fibrillating operation, the bobbin shaft may be manually stalled to allow godets 115, 116, to overfeed and form the loop which may be maintained thereafter by an automatic control device (not shown).
