Abstract
The machine comprises a succession of heads each provided with two superimposed rolls and arranged in alignment one behind the other. One of the roll support shafts of each head is connected to a particular hydraulic drive motor and is connected to rotate with the corresponding shaft of each one of the adjacent heads through a connection which is capable of being disconnected. All the motors are connected to the same source of fluid under pressure. In a preferred embodiment, in each head the shaft connected to the motor carries a notched pulley and is connected with the corresponding shaft of each of the adjacent heads by a notched belt engaged with the pulley it carries and with the pulley of the corresponding shaft.
