摘要： An improved twisting device for imparting a twist to the stranding elements of electrical cables, which twist alternates from section to section, in which two fixed twisting heads have installed between them a pair of movable twisting heads on a common frame which is moved back and forth thereby forming a pair of accumulators of alternatingly variable size as the movable twisting heads are moved back and forth.
