ABSTRACT:
A suction gripper device for transfer of boards and other substantially flat objects includes a suction plate having at its underside suction openings that are closable by way of calibrated flaps. The plate is connected with a vacuum vessel through a closable vacuum opening on the one hand, and on the other hand, through a calibrated opening that serves to effect a controlled leakage to keep the vacuum within the vacuum vessel at a pre-defined maximum value.
