Abstract
Winding machine and process for winding a material web, in particular a paper or cardboard web, onto a reel. The material web is guided by a carrying drum that can be supplied with suction, and a nip is formed between the carrying drum and the reel. The carrying drum, which has a perforated casing and/or is provided with circumferential grooves, is supplied with suction by way of at least one external suction box. The suction box is disposed with at least one suction opening opposite the circumference region of the carrying drum that is not wrapped by the material web. The suction box has at least one sealing element that cooperates with the carrying drum in the vicinity of the suction opening.
