A device for positioning thread guides in selectable points in a circular knitting machine, which has a unit for moving the thread guide closer or further away from the cylinder. The unit is a rod-and-crank system in which an intermediate region of the rod is slides guided with respect to a fixed slider. The end of the rod that supports the thread guide is adapted to move, as the crank is actuated, along a curved path from a spaced inactive position to an advanced thread delivery position. The unit is provided with elements for articulation to a fixed frame along an axis that is substantially parallel to the axis of the crank. An elastic return spring and an angular spacing piston are arranged between the unit and the frame and can be actuated selectively to move the thread position to different locations.

An impact protection device for a rod for positioning thread guides in a circular knitting machine. The thread guide has an approach and spacing unit formed of a rod and crank system. The end of the rod carries the thread guide and an intermediate region of the rod has a longitudinal slot which is slidably guided on a stud that is rigidly coupled to a fixed arm. The device has a compression spring mounted on the stud which presses the rod against the arm. Elastic elements mounted on a rod articulation pivot pus the rod against the crank. The spring and elastic elements allow small movements of the rod from the plane of arrangement of the path of the rod in case of impact with, or scraping against, another rod.

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.
