Abstract

Improvements introduced in the devices of regulation of thickness of the plank in the trolleys for sawing of trunks essentially characterized by having an electric motor of alternating current that moves a longitudinally located axes along the trolley; the pinions having the axle engage in the respective racks transversely displacing the trunk clamping device that has each of the same donkeys that form the carriage; the adjustment of the amplitude of the displacement is achieved by a contact placed on a disc that, if it is engaged, proportionally to the transversal displacement of the trunk, the contact in its rotation abuts the plate that closes it, which distances from it a certain angle when placed on the axis of the disc. A synchronous motor connected in self-sin or signal transmitter with another synchronous motor whose axis acts as a dial located in the control desk. When the contact closes, the force motor is braked by introducing direct current for a regulated time; with which the transverse displacement of the tronto in the desired position is interrupted; the contacts that return to their initial position are disconnected simultaneously to be able to initiate a new thickness regulation of the plank.
