<p>A device has two drive members rotatable on concentric axes of rotation (5), of which drive members a first drive member (7) is formed by first discs (11) and the second drive member (9) is formed by larger, second disc (13). The apparatus further has six guide bodies (17) which are each with a first end piece (21) at a first pivot point (25) pivotably connected to the discs (11) and are at the other end piece (23) provided with a suction cup (27) for the gripping of a flat-folded box. Between the two end pieces, the guide members are slidable in a guide element (29) that a second pivot point (31) is pivotally connected to the second drive member. To let the suction cups make the desired movement, the second pivot points (31) are at a greater distance from the rotational axes (5) than the first pivot points (25) the first drive body (7) is driven twice as fast as the second drive member (9).</p> |
