Abstract

998,091. Supporting and driving twist-tubs. G. SCHAFER, O. SCHAFER, G. SCHAFER Jr., and O. SCHAFER Jr., [trading as HINGELFISCHER G. SCHAFER & CO.], and DEUTSCHE EDELSTAHLWERKE A.G. July 21,1961 [July 21, 1960], No. 26463/61. Heading D1D. A false-twisting device for continuously crimping synthetic yarn comprises a hollow spindle or tube 1 mounted between, and magnetically supported and held in frictional driving engagement with the peripheries of, two pairs of discs 5 and 6. The magnetic field is produced by at least one axially magnetised ring magnet 2 and/or 2<SP>1</SP> rotating with the tube and/or with one or each of the pairs of discs. Polepieces 3 and/or 3<SP>1</SP> co-operate with extensions on a stationary armature 4, Figs. 1 and 4, rollers of magnetic material on the tube, Fig. 5, or with one another, Fig. 6. The or each magnet may be of high coercivity material e.g. a platinum-cobalt alloy, or of plastics in which ferro-magnetic powder is embedded, or of magnetic material having low mechanical rigidity enclosed in a protective sleeve of non-magnetic material
