摘要:
Process and device for transferring at least one of a fibrous material web and a strip of the fibrous material web from a moist releasing belt to an accepting belt in a web producing machine that includes a transfer region and a separating region arranged in this order in a web travel direction. The process includes guiding the accepting and releasing belts together at least in the transfer region, separating the accepting belt from the releasing belt in the separating region, and suctioning a surface of the accepting belt opposite a fibrous web and strip carrying surface so that the strip and the fibrous material web are carried by the carrying surface. When the strip is being transferred, the suctioning occurs at least the transfer region, and when an entire width of the fibrous material web is being transferred, the suctioning occurs at least primarily in die separating region. The device includes a transfer region, a separating region arranged downstream of the transfer region in a web travel direction, a releasing belt adapted to carry the strip and the fibrous material web to the transfer region, and an accepting belt adapted to receive the strip and the fibrous material web from the releasing belt in the transfer region. The device also includes at least one movable suction zone extending crosswise to the accepting belt and positioned so that the accepting belt is aided past the at least movable one suction zone. The at least one movable suction zone is positionable between the transfer region and the separating region.
