Abstract
A method and device for winding a material web, such as a paper web, onto a spool or equivalent through a winding nip formed between a cylinder, roll or equivalent and the roll that is being formed. The transfer of air taking place through the winding nip along with the material web to be wound is retarded and/or prevented by forming a positive pressure in the wedge-shaped area placed after the winding nip.
