ABSTRACT:
A clutch device interposed between a driving shaft 1 and a drum 2-4 rotatably mounted thereon to drive frictionally a yarn winding bobbin in a spinning, twisting or doubling frame comprises a cylindrical sleeve 5 carried by shaft 1, a string 6 wound on sleeve 5 and having one end attached to the hub 2 of drum 2-4, a plate 9 slidable on shaft 1 and to which the other end of string 6 is attached, a frictional abutment ring 11 secured to shaft 1, a spring 10 to apply plate 9 against ring 11, and a pusher 14 by means of which plate 14 may be moved apart from abutment 11 to de-clutch drum 2-4 from shaft 1. A frictional lining 13 is disposed on ring 11 to enhance its driving effect on plate 9 to more tightly wind string 6 on sleeve 5. Another frictional lining is provided on pusher 11 to act on plate 9 when the latter is disengaged from ring 11. A ring 16 mounted in the open end of drum 2-4 and equipped with a frictional lining 17 cooperates with the free edge of the cylindrical extension 9a of plate 9 to brake the drum at the end of the de-clutching stroke of pusher 14. In a modification string 6 is replaced by a solenoid of plastic material surrounded by an expansion limiting sleeve and a torque limiting system is interposed between the end of this solenoid and the drum.
