METHOD OF AND APPARATUS FOR CUTTING YARN LOOPS ON ONE FACE OF A FABRIC PARTICULARLY FOR PRODUCING VELVET

摘要

Method and device for laser cutting of wire loops arranged in parallel columns on one of the faces of a piece of fabric, in which the area of the focus of the laser beam is successively in contact with a certain portion of each loop, each time for a sufficient time to cause the combustión of at least part of the fibers constituting the loops, a procedure characterized in that a relative movement with respect to the adjacent loops of the same column is printed on each loop -near the focus point-., so that each loop is present at the focus point linked to the preceding loop, without interruption.
