Abstract: Apparatus for disentangling workpieces is described which consists of a container into which the entangled workpieces are placed, a series of air jets located in the base of the container, and an outlet assembly consisting of a pair of overlapping relatively slidable comb-shaped plates defining a series of slots of adjustable width. An electropneumatic circuit is arranged periodically to widen the slots to release any trapped workpieces, and to shut off the blowing air immediately prior to widening of the slots. A circulatory flow of the workpieces is established in the container and the disentangling is brought about primarily by the brushing action of the workpieces against the slots.
