Abstract

1,228,534. Open end spinning. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT LEGKOGO I TEXTILNOGO MASHINOSTROENIA. 5 Aug., 1969, No. 39039/69. Heading DID. An open end spinning device comprises a spinning chamber 5 with a fibre deflector 8 in the throat, the chamber being axially movable to the position shown in Fig. 2 when a transducer 12 indicates a drop in tension in the yarn leaving the chamber (i.e. a thread breakage or slackening) so that the incoming fibres 22 pass over the upper edge of the spinning chamber to be carried away along a suction duct 2. The chamber 5 is mounted on a driven spindle 10 carried in bearings 17 in a frame 16; an electromagnet 13 is linked to frame 16 and when transducer 12 indicates a drop in yarn tension it is energised to pull down frame 16 together with chamber 5 against springs 14 mounted in a fixed part of the frame. When the break is repaired yarn 23 is tensioned once more so that transducer 12 de-energises electromagnet 13 and springs 14 lift the spinning chamber into its working position.
