Abstract

1491652 False twisting devices HEBERLEIN MASCHINENFABRIK AG 14 April 1976 [15 April 1975] 15335/76 Addition to 1441689 Heading D1D A reinforcing member 25 and 26 having a thickness of at least 0.1mm and a higher modulus of elasticity than the surface 16, 23, 24 of the main and secondary friction elements is provided on the yarn input edges of the false twisting device according to the parent Specification 1441689. The latter false twisting device includes a disc 16, the rim(s) of which penetrate within an annular groove (3) of a main friction element 21, 22 which is in the form of a convex solid of revolution. The disc 16 and main friction element 21, 22 form a cusp in which the yarn is received and false twisted. The reinforcing member 25, 26, the surface layer 23, 24 of the main friction element and the rim portion 16' of the disc(s) may have substantially the same coefficient of friction with respect to synthetic textile yarns. The reinforcing member 25, 26 may comprise a metal film, a layer of cured synthetic resin, or ceramic. The reinforcing member 25, 26 may be made of the material of the disc 16 and the core 21, 22 of the main friction element, see Fig. 3 (not shown).
