<p>The head has a number of tools (5) mounted on corresponding shafts and supported by a rotating case (8), the carter (8) being kinematically connected to a driving shaft (1), so as to draw a motion from there, with a predetermined angular velocity. To the driving shaft are kinematically connected also the shaft of the tools, which derive their own motion from the same shaft with an angular velocity different from that of the case. The case is connected to the driving shaft via a round-per-minute reducer located inside the same head, the tools being connected to the driving shaft via a round-per-minute overgear.</p> |
