Abstract
A wind-up apparatus for forming laps comprises a first winding roller, a second winding roller, a lap bobbin tube and a plurality of, for instance four, calender rolls. The calender rolls serve for consolidating a fiber layer into a windable fiber web. Each calender roll of the predetermined number of calender rolls has a predetermined rest position and an operating position. A guide structure is provided for the calender rolls to enable the calender rolls to be movable within a given mobility range defined between the rest position and the operating position. The guide structure comprises force-producing elements for moving the calender rolls into the predetermined rest position thereof.
