ABSTRACT:
An apparatus for sensing a parting in any of the strands of sliver fed from a creel to the drafting rolls of a high speed textile draw frame to stop the drawing process in response to a sliver parting. A plurality of sliver guides are mounted on an elongate arm which is compact and readily mounted on the creel. The sliver guides are U-shaped with inturned upper end portions defining a restricted opening at the top portion and a capacitive sensing switch positioned in the bight portion thereof. The sliver guides also include a low coefficient of friction coating to reduce the accumulation of lint. Cylindrical post separators are positioned alongside the path of the slivers to maintain separation and prevent entangling of adjacent slivers. Logic and control electronics are contained within a housing carried by the elongate arm.
