Patent ID: 8500057

Claim:
A method of adhesive-free threading of a thick fibrous material web, especially a pulp web, for winding around a winding body in a continuous operation, comprising the steps of: supporting the winding body between a first bearer drum forming a first nip with the winding body, and a second bearer drum forming a second nip with the winding body, wherein the first bearer drum and the second bearer drum define an open gap therebetween; wrapping the fibrous material web about the first bearer drum in the continuous operation; passing the fibrous material web wrapped on the first bearer drum into the first nip formed between the first bearer drum, and the winding body. deflecting the fibrous material web upwardly through the second nip formed between the winding body and the second bearer drum; wherein the second nip defines a threading side of the winding body opposite the first nip. diverting the fibrous material web in a circumferential direction defined by the winding body, and away from the second nip with a threading device; guiding the fibrous material web with an unfolded leading edge in a direction toward the first nip formed between the winding body and a first bearer drum; and wherein the step of guiding is performed only from the threading side of the winding body with the threading device which moves to engage the fibrous material web, the threading device catching the leading edge of the fibrous material web by interaction with the fibrous material web and the winding body with a diverting roll and a guide plate, and directing the fibrous material web in to the first nip.
