Abstract

1,236,038. Stop motion. TORAY INDUSTRIES Inc. 3 Dec., 1968 [12 Dec., 1967], No. 57436/68. Headings DID and D1J. A device for stopping spinning in an openend device upon the occurrence of a thick part in the produced yarn comprises a device such as a tube 3c through which individual fibres are carried in an air flow to the chamber 4, a duct 10b whereby compressed air is fed to tube 3c to produce the air flow, an electromagnetic valve 10a in duct 10b and means downstream of chamber 4 to detect a thick part in the yarn and cause valve 10a to be actuated to stop the supply of compressed air and thus halt the spinning process. As shown a slit is provided between plates 9a, 9b spaced so that a thick part is caught and the yarn broken; this allows a biased feeler 8b to swing sideways, and operate a switch which causes valve 10a to be operated. A suction nozzle 21 catches the loose end of yarn and prevents it being drawn back into the spinning chamber by centrifugal force. A second biassed feeler 8c is provided at the exit of the spinning chamber to stop the supply of compressed air should the yarn break or become weak and slack in this region. In Fig. 2 not shown the slit flats (19a, 19b) are inclined to the yarn so that when a thick part engages the slit the yarn is deflected sideways to shift a feeler (8b) and close valve 10a. In Fig. 4 not shown the slit is at one end of a plate pivoted about a horizontal axis. When a thick part engages the slit the plate is pivoted against a biassing spring thus releasing a switch which closes valve (10a).
