(54)	Press for moulding clay manufactured articles

(57) A press for moulding clay articles driven by an electric motor (2) wherein the means (13) for controlling the motor are adapted to change the rotation speed of the motor, by accelerating at the end of the moulding step and decelerating at the start of the moulding, so as to modify the moulding law of the press in accordance with a predetermined desired profile. The press is either a cam actuated press (9) or an eccentric-shaft (19), and the control of the speed of the electric motor (2), preferably a D.C. brushless motor, employs at least one encoder (7).
