<p>In the narrowing device, the narrowing fingers are fastened to a thread guide bridge. Cam discs and lateral displacement cams are arranged in the narrowing fingers slidable over grooved shapes, and are connected via a slide member, slide rods and a coupling member with the narrowing needles. The complete narrowing process, including the displacing of the narrowing needles, takes place during the slide reversing during one revolution of the grooved shafts which pass through the narrowing fingers and carry the slidable cam discs and lateral displacement cams.</p> |
