CA 2115655

Winding machines with two king rolls (1, 2) are known for winding webs of material (5) onto spools (6); the winding rollers (4) rest on these king rolls during the winding process, when the web of material (5) which passes in part around a king roll (1) is fed from below through the gap between the king rolls (1, 2). When the winding rollers are changed, a cutter (14) with a blade (15) is moved through the gap between the king rolls in order to cut the web of material (5). In order to reduce the weight of the winding rollers (4) on the king rolls (1, 2) there is an air box (8) that extends across the whole working width within the wedge-shaped gap between the two king rolls (1, 2), and this incorporates a compressed air feed (9); this air box seals off the gap between the king rolls (1, 2) and incorporates an air outlet slot (11) that is open towards these. According to the present invention, the blade (15) of the cutter (14) is secured to a support rod (18) that is arranged in the air box (3) so that it can move up and down; it can be moved up through the air outlet slot (11) into a cutting position within the roller bed (3) and can be lowered completely into the air box (8).
