ABSTRACT:
To permit axial excursion of the gripper spindle (2) with respect to the shaft (6) of a transfer drum or printing cylinder upon bend-through of the shaft, a spindle axial alignment element (13) is located approximately centrally of the gripper spindle (2) which is axially maintained in position by being engaged, at both axial sides, by guide rollers (14, 15) secured to the shaft (2). Thus, the gripper spindle is axially aligned with respect to the shaft essentially at the center thereof. The axial alignment element (13) in form of a plate between the rollers (14, 15) is shorter by a distance (d) than the radial distance between the shaft (6) and the gripper spindle (2) to permit radial excursion of the shaft (6) which occurs particularly at high printing speeds, thereby preventing transfer of forces on the gripper spindle (2) upon bend-through of the shaft (6). The lateral bearings (4, 5) are floating bearings, permitting angular and axial excursion of the gripper spindle with respect to the support elements (17, 18) supporting the bearings on the shaft.
