Abstract:
A gripper for retaining sheet-like articles (21) comprising two gripper legs (11, 12), each gripper leg (11, 12) having a substantially flat inner side facing the other gripper leg (11, 12), the gripper legs (11, 12) being mounted to pivot relative to one another such that the grippers legs move in a direction extending transversely to said flat inner sides to assume a closed position and an open position, wherein, in said closed position, the gripper legs (11, 12) are adapted to clamp a sheet-like article (21) with both of said flat inner sides contacting said sheet-like article, an actuating device acting on at least one of the gripper legs (11, 12) to produce a pivoting movement of the two gripper legs (11, 12) relative to one another, said actuating device being movable back and forth in a translatory manner for the changeover between said open position and said closed position of the gripper legs (11, 12) and having at least one sliding part (18) which is movable back and forth in a translatory manner when the actuating device is moved back and forth in a translatory manner and which acts on said at least at least one gripper leg (11, 12) to subject the latter to a force in a direction toward said open position during a translatory movement of the sliding part (18) in one direction (A) and in a direction toward said closed position during a translatory movement of the sliding part (18) in the opposite direction (B).
