Abstract
The fiber processing plant has a pneumatic flock feed system which is operated in dependence on an operating parameter which, in turn, is dependent upon the number of fiber processing machines which are operating at a given time. In one embodiment, a meter is disposed in a feed duct of the flock feed system between a fan and a first of the fiber processing machines in order to sense the static pressure therein. The meter is used to sense a difference in pressure caused by one or more fiber processing machines becoming inoperative so as to cause a switching on or off of the fiber supply to the feed duct.
