摘要

Gripper device on a transferring drums for conveying a sheet in a printing machine,with grippers set at a distance to a gripper shaft,with radial bearings for holding of the shuttle shaft, parallel to the axis of rotation of the transferring drums,with a gear mechanism to cyclic pivoting of the shuttle shaft,with a torsion rod in the interior of the gripper shaft, whose first end of the spring is fixed to the shuttle shaft and whose second end of the spring is fixed to the drum body is connected to the transferring drums,characterized by the,that an axial bearing (18) for the gripper shaft (11) is provided,the axial bearing (18) on a with the drum body (1) is connected to the bearing element (7) and at a with the looper shaft (11) is connected to the bearing element (17) is supported,and in that the torsion bar (24) is stressed in tension, so that the the axial bearing (18) which is supported on the bearing elements (7, 17) of play, on the axial bearing (18) bear.
