Abstract
Apparatus is disclosed for forming S-Z twisted strand units which comprises a frame and an elongated body mounted to the frame for rotation about a longitudinal body axis. The body is comprised of an assembly of tubules extending side by side longitudinally between opposite body ends. A first twisting head is rigidly mounted to one end of the elongated body which has a sheave mounted for rotary movement about a sheave axis transversing the longitudinal body axis. A second twisting head is rigidly mounted to the other end of the body having another sheave mounted for rotary movement about another sheave axis which transverses the longitudinal body axis. Means are also provided for rotating the elongated body in alternate directions about the longitudinal body axis. So constructed, strand units may be passed a plurality of times through the elongated body by routing the strand units through the body between the first and second twisting heads successively through the body without coming into contact with one another, and the body with its assembly of rotated in alternate directions thereby forming the strands into S-Z twisted strand units.
