A feature of a pressure roll or a continuous pressure belt for the formation of a reeling nip using a parent roll in a reel-up for the reeling up of a material web, in particular paper web or paperboard web, is that the roll surface or, respectively, belt surface adjacent to the reeling nip has helical, an at least single-start groove, the depth of which is in the range from about 0.4 mm to about 1.5 mm, and the maximum width of which is in the range from about 35 to 60 mm.

Pressure roll or continuous pressure belt

Process and winding machine for winding a continuous material web on a reel spool forming a wound reel. The process includes, upon attaining a desired roll diameter in an old wound reel, closing a new winding nip between a reeling drum and a new reel spool brought into a standby position. In this regard, the reeling drum and the old wound reel are jointly displaced while maintaining the old winding nip formed between the reeling drum and the old wound reel. After the closing of the new winding nip between the reeling drum and the new reel spool, the linear load in the new winding nip is adjusted, controlled or regulated by a corresponding displacement and tightening of the reeling drum.

Process and winding machine for the continuous winding of a material web

A reeling machine for winding a web, in particular a paper or cardboard web, for the formation of a wound web roll on a reel-spool, with a reeling drum, which forms a winding nip with the wound web roll and with at least one separating mechanism, which separates the web in a separating area. In the reeling machine, the separating mechanism is advanced before the separating process--as seen in vertical direction--from above to the separating area, which lies at a short distance to the outer periphery of the new reel-spool and/or--as seen in run direction of the web--to the winding nip between the reeling drum and the new reel-spool.

Reeling machine and a process to reel a web

A winder for continuous winding of a material web, like a paper or board web, on a winding spool to form a wound reel. A contact pressure drum is rotatably supported on a displaceable transport device and the drum itself is displaceable with respect to the transport device to form a widening nip with the wound reel. The transport device also supports a primary bearing for holding an empty spool during the start of the winding process. The bearing for the empty spool is between the contact pressure drum and a secondary bearing for supporting the wound reel in the final winding position. The primary bearing for the initially empty spool is fixed in location on a transport device. The transport device is in turn transportable toward and away from the secondary bearing for the wound reel. The contact pressure drum is supported to move along with the transport device as well as also being displaceable with respect to the transport device to maintain the line pressure during increase in the wound spool diameter.
