Abstract

Apparatus for surface treatment of workpieces has a rotary horizontal cage with inclined end walls and a set of elongated rod-shaped or bar-shaped components between the end walls. The end walls are rotatable in inclined carriers which cause them to act not unlike swash plates and to cause the components to reciprocate in response to rotation of the cage about its axis. The end portions of the components are tensioned by springs which react against the end walls and bear against axially adjustable nuts at the free ends of the components at the outer sides of the end walls. The end walls have relatively large holes to ensure that the components are not flexed during reciprocation in response to rotation of the cage. Workpieces to be treated, e.g., by sprays of solid particles, are introduced through one of the end walls and advance toward the other end wall at a speed which is determined by the extent of reciprocatory movement of the components and the rotational speed of the cage.
