Abstract

The reinforcing bars or rods are worked using rolling rollers which are provided in a driven tool head. In order to achieve a uniform change in structure during profiling, in the range of action of each individual roller, the apparatus is provided with a servo motor (12) which acts via a disc (16) on a disc (15) which, for its part, is assigned to the outer rotor (9). The servo motor (12) should be configured in such a way that it compensates the friction forces, the bearing friction, the mass moment of inertia etc. which occur in the system. In this arrangement, the inner rotor (11), via the mating disc (10), drives the disc (5) which serves to drive the head. In this arrangement, the outer rotor (9), via the disc (8), drives the mating disc (6) and, via a sun gear (4), the latter drives a roller-driving gear (13), the roller shaft and hence the rolling roller (3) which profile the rod (7) thereby being driven.
