Abstract
In a lap winding apparatus for forming a wadding lap from a wadding web, a lap receiving tube or the wadding lap formed thereon is supported on two winding rollers. On both sides of the winding rollers, support arms are provided which in the upper end region have means for receiving the tube and at the lower end region are connected with a pivoting mechanism which is operated by a pneumatic cylinder arrangement. Calender rollers compress the wadding web before the winding thereof. In order to prevent as far as possible 'breathing' of the wadding web between the last calender rollers and the wadding lap a smoothing plate condenses the wadding web shortly before reaching the wadding lap for a last time. The smoothing plate is resiliently secured on both sides of the winding rollers to respective swing arms. On both sides of the winding rollers there is provided a respective swing arm and a force transmitting lever fixedly secured to a sleeve. In order to hold the smoothing plate at a substantially constant distance from the wadding lap that gradually increases in size in operation, the force transmitting levers are pivoted by rollers secured to carrier arms.
