ABSTRACT:
The rotating head comprises oscillating blocks 1 mounted on inclined pins 2 connected by means of connecting rods 5, the rods being mounted on eccentric pins fixed to toothed helicoidal wheels 9. The wheels mesh with a worm screw 10 having a vertical axis, the worm screw being mounted on the fixed structure of the apparatus. The entire complex is mobile at reduced speed, a fact which reduces the wear and consequently the necessity of maintenance and substitution of parts during operation.
