ABSTRACT:
A rotatable thread arrester, associated with a thread feeder, includes an arrester finger for the thread that is movable with respect to the reel of the feeder under the control of a movement device and engages the thread so as to stop its unwinding from the reel and viceversa in order to damp the peak of the mechanical tension generated on the thread by the contact with the arrester finger. The arrester finger is oscillatably suspended about an axis "x" that is parallel to the axis "y" of the reel and is controlled by the action of a motor which rotates the arrester in the thread unwinding direction, so that the arrester finger, in the arresting position, follows the thread unwinding from the reel.
