ABSTRACT:
A knitwork drawing device which has a hollow piston rod movable axially through one of the needle cylinders in a double cylinder circular knitting machine, and a knitwork retaining member arranged at the height of the stitch-formation area and rotatable with the needle cylinders. The hollow piston rod is secured to a fluid-operated piston slidable in a cylindrical chamber coaxial with the needle cylinders. Tensioning of the knitwork is effected by leaving the hollow piston rod to rest on the knitwork being knitted, which is held at its initial portion by the retaining member internally of the hollow piston rod and by the needles which continue to knit externally of the hollow piston rod. The whole stroke of the piston and hollow piston rod is thus the half of the whole length of the knitwork and the axial dimension of the knitting machine is considerably reduced.
