Abstract
A feeder for supplying fibers to an apparatus for forming a preliminary web having a holding shaft, to be supplied with fibers from above through a conveying line, and a distributor, which is disposed between the holding shaft and the conveyor line and serves to distribute the arriving stream of fibers over the width of the shaft. In order to ensure an undisturbed distribution of fibers, the distributor has at least two distributing lines, which open into the holding shaft and are connected to the conveying line in alternation by a change-over valve.
