Abstract (en)
[origin: US4637565A] 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. Each calender roll is movably mounted at each of its opposite ends by means of a spring pair receiving the calender roll. Each spring pair is fixedly connected at one end to a bearing member of the related calender roll and at its other end by means of a carrier to side walls of the wind-up apparatus. A piston of a pneumatic cylinder moves the calender rolls from a rest position, in which there is a spacing D between the calender rolls and a spacing E between the last calender roll and the first winding roller, into a working position in which the calender rolls are pressed against one another in the absence of an intervening fiber layer. The position of the calender rolls in their rest position is maintained by the spring pairs.
