Abstract
An improved clearer for the drawing rolls, namely the top rolls, of spinning machines and like equipment. The clearer comprises a main frame or supporting structure for a clearing belt. The frame is pivoted adjacent the rear end of the apparatus. Carried by a portion of the frame are spring members which respectively press the belt into frictional driving engagement with a serrated roller forming part of the roll system and into clearing contact with one of the forward rollers which is to be cleared. The relationship of the parts is such that the belt also engages the upper surface of at least one other roller which is forwardly mounted relative to the roller just mentioned, to clear the same. Also, the clearer is provided with idler rolls for the belt which are located lower than the top of the cross member of the frame thus to reduce the overall vertical dimensions of the device and to get more "wrap" on the forward top roll, resulting in better clearing.
