Abstract

The body blanks (10) are moved through, with overlapping longitudinal edges, between an inner and an outer electrode roller (14, 24), the axes (16, 26) of which lie substantially in a common plane (II--II) normal to the direction (A) of the axes of the body blanks (10). Also lying in this plane (II--II) are the axes of a plurality of sizing rollers (34, 36, 38) which are disposed in a ring and one of which (38) is disposed diametrically opposite to the outer electrode roller (24). This sizing roller (38) and a guide roller (42) which is disposed in front of it in the direction (A) of the axes of the body blanks (10) are encircled jointly by an endless conveyor element (46). The guide roller (42) and hence also the conveyor element (46) can be driven by a servomotor (50) which is controlled according to the signals of an angle-of-rotation transmitter (30) rotating with the outer electrode roller (24). The body blanks (10 ) are pulled forwards by the conveyor element (46) and stabilized in their forward motion as a result.
