ABSTRACT:
Apparatus for cutting sheets of plate glass, particularly for making automobile windows, according to a profile programmed in a digital control unit the control output of which is coupled to electrohydraulic amplifiers, each of which controls the movements of a hydrodynamic cylinder moving on a fixed piston rod. A cutting head is fixed to one of the cylinders, while a table to bring the sheet of glass to be cut into contact with the cutting head is fixed to the other cylinder. The two cylinders move in perpendicular directions, and their coordinated movements cause the glass to be cut in a programmed profile. A belt conveyor is incorporated in the machine to carry the glass to the table, and may assume a raised position for transport and a lowered position at rest (FIG. 1).
