摘要： A device for transferring sheets in a sheet-processing machine includes a cylinder having at least one gripper device for the sheets, and a control device for opening and closing the gripper device, the control device having a first control cam for recto printing and a second control cam for recto/verso printing, at least one follower element for following the first and second control cams, each of the first and second control cams being formed with a through opening for accommodating a bearing element and, respectively, a cutout formed in the periphery of the first and second control cams and extending as far as the through opening for fitting the first and second control cams to and removing them from the bearing element radially. The first and second control cams, respectively, are of unipartite construction and, in peripheral direction, are aligned with one another so as to provide an at least approximately closed contour path for the at least one follower element.
