Abstract (en)
A device for automatically doffing the hollow lap rollers comprises, for each hollow lap roller, a driving movable means (5, 5A, 5B, 5C, 5D) for supporting and ejecting the hollow lap roller (4) already loaded with the roving (1); a doffing element (7) with a closed loop path, provided with doffing hook elements (71); a locating element (9) for locating the empty hollow lap rollers and supplied by sliding guides (90); auxiliary means (150) for ejecting air blows in order to aid a proper starting of the winding of the new hollow lap rollers to be filled-in as well as auxiliary means (6) adapted to press, at the start of a new winding step, the empty hollow lap roller on the hollow lap roller cylinder (2) in order to safely trigger the winding thereof. The device is adapted to speed-up the doffing operation, and allows to save labour and time. <IMAGE>
