Abstract

1289284 Forwarding rollers TMM (RESEARCH) Ltd 19 April 1971 [6 March 1970] 10925/70 Heading DID In a yarn delivery assembly suitable for open-end spinning machines a pressure roller 2 mounted on an arm 4 fixed to a shaft 5 is biased towards a driving roller 1 by a spring- pressed plunger 16 acting on a roller 15 of a bell-crank lever 10 pivoted at 9 on an arm 8 which is fixed to the shaft 5. Should the yarn break and cause separation of the rollers by winding around one of them the roller 15 is driven along a cam surface 20 until it passes a dear-centre position relatively to the plunger 16 and pivot 9 whereupon the plunger is no longer effective to bias the roller 2. Such release of the roller 2 may cause operation of a warning signal or a stop motion to prevent further delivery of yarn to the rollers. When the roller 1 is common to a number of rollers 2 an indication that one of the rollers 2 has been released is given by the position of its resetting handle 13 relatively to the other handles.
