Abstract
A method of adhesive-free threading of a fibrous material web for winding around a winding body includes the steps of diverting the fibrous material web in the circumferential direction of the winding body, guiding the fibrous material web with its unfolded leading edge ahead in the direction of a nip formed between the winding body and a drum and catching the leading edge of the fibrous material web by interaction with the fibrous material web and/or the winding body. An apparatus for adhesive-free threading of a fibrous material web for winding around a winding body has a diverting device for diverting the fibrous material web in the circumferential direction of the winding body and a mechanical guide for guiding the fibrous material web with its unfolded leading edge ahead in the direction of a nip formed between the winding body and a drum.
