Abstract (en)
[origin: EP0911434A2] The yarn cutter (15) is a single cylindrical or slightly conical flat pot-shaped component. Its edge has projecting cam tooth structures (18') with blunt edges and set-back cutters (17') with sharp edges. In an Independent claim the cutter is deep-drawn from a plate, with material cutting to form the sharp edges. It may be sintered from powder metal, or it may be die cast or injection molded, followed by edge sharpening and plating. Preferred Features:- The cutter (15) is a drawn metal plate component, with an outer edge worked to give distributed cutting tooth sections aligned towards the ring spinner spindle, to form cam structures. The outer edge of the cutter can be shaped into overlapping tabs giving alternating cutting edges (17') and projecting cam structures (18'), with the tabs for the cams aligned towards the spindle. The cams can be formed by bending back the tongue tabs. A gap is between the cams and the cutters. The cams (18') are angled against the spindle axis, so that the free ends point away from the spindle axis. The cutter can be structured so that projecting corrugations (24) act as the cam structures and the valleys are the cutters.
