Grosse has introduced its patented UniShed positive electronic jacquard head. The shed formation in the UniShed is achieved by leaf spring. Each leaf spring is connected to a heddle that controls one warp end. The leaf springs which are controlled by actuators control the bottom shed as well as the top shed (positive shed type). The dimensions of the jacquard head and the individual control of each heddle (warp end) allow the heddles to be set vertically. These settings permit the elimination of harness cords, hooks, magnets, pulleys, pull down springs and more significantly, the gantry. The jacquard head is mounted directly on the side frame of the weaving machine, thus allowing quick style changes.
