Abstract

The invention relates to a transfer cylinder (1) for a rotary press or for use in a rotary press, which allows a printing width of at least five printed pages and which comprises a first fastening channel (3) and a second fastening channel (4) for fastening at least two printing linings. These fastening channels are disposed in different axial sections of the transfer cylinder (1) and are offset by 180° in relation to each other in the peripheral direction of the transfer cylinder (1) or extend each other in alignment. The first fastening channel (3) extends continuously in the longitudinal direction of the transfer cylinder (1) across at least three printed pages and the second fastening channel (4) extends continuously in the longitudinal direction across at least one printed page.
