ABSTRACT:
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.
