Pulling with reversing device and process for circular knitting frames

摘要

Device and process for pulling with reversing circular knitting frames, comprising a cylindrical shell coaxial with the needle cylinder or the needle cylinders of the frame, and positioned above the plane of formation of the knitted fabric. A cylindrical sleeve is positioned coaxially with the shell, and axially slidable within the shell. A rotatable expandable tensioning piston is positioned coaxially with the sleeve and axially movable within said sleeve to expand and clamp the knitted tubular fabric inside the sleeve and drag upwardly the sleeve as well as the tubular knitted fabric.
