Title: Yarn stripper

Abstract: Disclosed is a plate-like yarn stripper device for use in removing staple fiber yarns from rotatable elements of circular cross-section, such as in the removal of yarn wraps underwound beneath a spindle blade to anchor the yarn threadline in the doffing and donning of cops on a ring spinning frame. The stripper is formed with a central hole defining stripping edges at a surface of the plate, these edges being spaced from the yarn-wound element by a prescribed distance such that when the element is rotated the wound yarn will buffet the edges and be abraded, weakened and cut or otherwise severed in the stripping action. Personnel safety is enhanced in use of the stripper by the absence of peripheral sharp edges, bristles or other abrasive external surfaces.
