Abstract
In each twisting unit of a multiple twisting apparatus, a two-for-one twisting assembly imparts a first twist to each component yarn while a ring twisting assembly imparts a second twist to .[.a.]. .Iadd.the .Iaddend.doubled first-twisted yarns. A plurality of first twisted yarns are doubled under tension control and the doubled yarn is taken up by a feed mechanism so as to be supplied to the ring twisting assembly under tension control via a yarn passage formed behind the two-for-one twisting assemblies. The two-for-one twisting assemblies are arranged in two alignments along a lengthwise direction of the apparatus. All driving members are driven synchronously at least at a starting period and at a time of stopping the twisting operation.
