Abstract: The invention relates to a sleeve, particularly a rubber blanket sheath, for a printing machine. The sleeve (10) has a two-layer structure comprising an internal layer designed as support layer (11), and an external layer designed as cover layer (12) and used for the print transfer, with the external or cover layer (12) being connected directly to the internal or support layer (11). A three layer composite sheath also is disclosed.

Abstract: The transfer blanket (10), in particular a rubber blanket, for a printing press, has a carrier layer (11), a covering layer (12) and at least one intermediate layer (13, 14, 15) which is positioned between the carrier layer and the covering layer, the carrier layer protruding, compared with at least one intermediate layer, at at least one end of the transfer blanket (10), using which end the said transfer blanket (10) can be fastened at a clamping point (17) of a printing press, and ends of the or each intermediate layer, which are of shortened configuration compared with the carrier layer (11), being sealed with the aid of a sealing layer (16). The sealing layer (16) extends over the carrier layer (11) in such a way that the transfer blanket can be fastened at the clamping point of the printing press at least via the carrier layer and the sealing layer.

Abstract: The most uniform possible temperature variation along the circumference of a transfer cylinder in a rotary printing machine is achieved by arranging a highly thermally layer made of a material having a thermal conductivity significantly higher than steel under a rubber blanket on the transfer cylinder for distributing heat from the rubber blanket along the direction of the surface of the transfer cylinder. The highly conductive layer is arranged on a support of the rubber blanket.

Abstract: A plate cylinder for a sleeve-type printform, particularly an aluminum offset printform, with a ramp-like transition piece as a guide surface for the mechanical expansion of the sleeve-type printform onto the larger cylinder diameter. At least the surface area of the plate cylinder that is covered by the ramp-like transition piece has a highly wear-resistant and pressure-resistant slide surface of a material different from the remaining surface material of the plate cylinder to prevent abrasion when the printform is slipped onto the plate cylinder.
