Abstract
A pusher needle wherein the oscillating movement in horizontal and vertical direction is replaced by an oscillating rotational movement affording an increase in the needle frequency, and thus, a production increase during the stitch formation. The oscillating rotational movement is caused by a curved construction of the pusher guide and the pusher portion displaceable therein.
