description an axial section through a cylinder as well as portions of lateral plates of a frame of a machine into which the cylinder has been placed are shown in fig1 the axial section extends along the dash dotted line identified by i u2014 i in fig2 two partial cylinders 01 02 of which the body of the cylinder represented in fig1 is composed are depicted in fig1 using different hatching with these hatchings rising for the first partial cylinder 01 and descending for the second partial cylinder 02 a central shaft 13 is part of the first partial cylinder 01 central shaft 13 is supported at one or a first location such as at the left in fig1 by a bearing 14 for example by a rolling bearing 14 in a first lateral frame plate 16 of a folding device the central shaft 13 can be driven by a first drive motor 17 whose motor housing is fixedly connected with the lateral frame plate 16 by the use of a flange 18 two arms 19 which are fastened on the central shaft 13 support a first cylinder segment 21 which constitutes a portion of the circumferential surface of the cylinder and which first cylinder segment 21 supports a function element of a first group for example a holding element and in particular a strip which is not specifically represented with spur needles or at least one gripper as can be seen in fig2 the first partial cylinder 01 has.
