摘要: A method and apparatus (100) are provided for facilitating folding of material (154) fed through a nip (108) between two rolls (104, 106) having tucker (102) on one roll corresponding gripper (110) the other roll, by using resilient element tip (114) that is moveable from neutral position thereof, elastic deformation at least portion body (112) element, directing into (110). The may have formed partially elastically fixedly attached proximal end thereof to roll. distal be wedge-like (134) vacuum ports extending portion, securing an sheet being 106).
