ABSTRACT:
A method and apparatus is provided wherein a pressed material is withdrawn from a lower metal mold in a press in accordance with a horizontal, pivotal movement and a vertical, linear movement of a carry-out arm, and a material to be pressed is fed from a preceding stage to the press in accordance with a horizontal, pivotal movement and a vertical, linear movement of a carry-in arm. In this method of feeding a material to be pressed, the height of a path along which the carry-out arm is turned is set greater than that of a path along which the carry-in arm is turned. The operations of the carry-in arm and carry-out arm are timed in such a manner that a material being newly fed and a pressed material being removed are overlapped as they are vertically spaced at a predetermined distance from each other, in a position above a lower metal mold in the press.
