Abstract
Abstract Apparatus for supplying fibrous material to a plurality of fiber processing machines which are arranged in satellite groups with respect to a source of fiber supply. There is a feed duct for each machine and a conduit for each group connected to the feed ducts of the group. Distribution valve means selectively connect each of the satellite conduits to the source of fiber supply and fans located in each conduit between the valve means and its feed ducts draw fibers from the source and blow them toward the feed ducts when the conduit is connected to the source by the distribution valve means.
