Abstract: 1,088,351. Stop motion. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. Oct. 23, 1964 [Oct. 24, 1963], No. 43256/64. Heading DID. [Also in Division F2] In a textile machine for processing slivers, rovings or yarns comprising a number of parallel drawing devices feeding material to spindles, a stop motion is provided between each drawing bend and associated spindle to interrupt the drive to the associated drawing head on breakage of the material. A constantly rotating shaft 14 extends along the length of a machine and carries the bottom front rollers 1. Drive is taken from shaft 14 to a shaft 15 running the length of the machine and passing adjacent the lower rollers 2, 3 of centre and rear drafting roller pairs. The rollers 2, 3 of each head are driven from shaft 15 via a clutch mechanism which is disengaged when the material breaks between the associated drafting head and spindle. The stop motion, see Fig. 3, not shown, comprises a feeler (57) which falls when the material (10) breaks to close an electrical circuit to operate a solenoid which disengages the clutch.
