Abstract

A compacting head has an inside wall-smoothing cylinder with cover plate rollers which are powdered round a drive shaft axis in one direction and which rotate round their own axis opposite to this. Thus the cover wall (3) of the smoothing cylinder (2) rotates round drive shaft (1) and the radially compacting rollers (5a-d) are geared (10) drivably round their own axes to the drive shaft (1) using a ratio selected to give a roller peripheral speed equal to their rotation speed. Gearing (10) is arranged inside the cylinder and the rollers have blades (11) on their upper endface and project axially with radial play into peripheral excisions (12) round a circular disc (13), rotatably mounted on the shaft. The top endfaces of the rollers lie flush with the top face of the disc as against the roller circumferences which project beyond the discs.
