Abstract:
A method of manufacturing a fiber fleece by means of a nonwoven producing means and a fleece laying machine, which performs laying movements by means of which a fleece web having a thickness variable across a laying width is generated from a single or multi-layered nonwoven web continuously discharged at a constant speed by the nonwoven producing means, wherein a speed, at which the fleece laying machine takes in and deposits the nonwoven web is constant and the nonwoven web is longitudinally drawn in a drawing process on a path between the nonwoven producing means and the fleece laying machine cyclically in adaptation to the laying movements of the fleece laying machine, wherein a buffering of the nonwoven web is taking place in the path of the nonwoven web in one of (a) downstream the drawing process, to obtain an adaptation of fluctuations of the speed of the nonwoven web leaving the drawing process caused by the cyclic drawing process to a constant speed by which the nonwoven web drawn is taken in by the fleece laying machine, and (b) upstream the drawing process to obtain an adaptation of fluctuations of an intake speed of the nonwoven web into the drawing process caused by the cyclic drawing process to the constant speed by which the nonwoven web is supplied by the nonwoven producing means.
