Abstract
A printer includes a cylinder pair that consists of a forme cylinder and a transfer cylinder. A satellite or steel cylinder forms a print position as it cooperates with the transfer cylinder of the cylinder pair. The forme cylinder and the transfer cylinder are a fixed coupling drive assembly which is driven by a common drive motor. The drive assembly of the cylinder pair and a drive system for the satellite or steel cylinder can be selectively mechanically coupled with each other by use of a coupling.

A printing unit, having a pair (02) comprised of a first forme cylinder (03) and a first transfer cylinder (04) cooperation with the forme cylinder (03), as well as a satellite cylinder (08) which, together with the transfer cylinder (04) forms a print location (09), wherein the drive mechanism of the forme cylinder (03) and the drive mechanism of the transfer cylinder (04) are fixedly coupled with each other and are driven during printing by a common first drive motor (06), which forms a drive assembly (07) with the first forme cylinder (03) and the first the transfer cylinder (04), characterized in that the drive assembly (07) of the pair (02) and the drive mechanism of the satellite cylinder (08) can be selectively switched and mechanically coupled with each other via a first connector (12).
A printing unit having at least two pairs (02, 14), each consisting of a forme cylinder (03, 17) and a transfer cylinder (04, 16) which, together with a satellite cylinder (08), form two print locations (09, 18), wherein the drive mechanisms of at least one of the pairs (02, 14) are fixedly coupled with each other and, together with a common drive motor (06, 21), constitute a drive assembly (07, 33), characterized in that the driving of the satellite cylinder (08), which is embodied without its own drive motor, can be selectively coupled with the drive assembly (07, 33) or can be released from the drive assembly (07, 33) of the at least one pair (02, 16).
A printing unit having four pairs (02, 14, 29), each consisting of a forme cylinder (03, 17, 31) and a transfer cylinder (04, 16, 32), each cooperating with the forme cylinder (03, 17, 31), as well as at least one satellite cylinder (08) which, together with the transfer cylinders (04, 16, 32), forms a print location (09), wherein the drive mechanisms of the forme cylinder (03) and the transfer cylinder (04) of at least one of the pairs (02) are fixedly mechanically coupled with each other and are driven during the printing process by a common first drive motor (06) which, together with the coupled pair (02), forms a drive assembly (07), characterized in that the drive assembly (07) of the coupled pair (02) and drive mechanism of the satellite cylinder (08) can be selectively switchably mechanically connected with each other via a connector (12).
A printing unit having four pairs (02, 14, 29), each consisting of a forme cylinder (03, 17, 31) and a transfer cylinder (04, 16, 32), each cooperating with the forme cylinder (03, 17, 31), as well as at least one satellite cylinder (08) which, together with the transfer cylinders (04, 16, 32), forms a print location (09), wherein the respective drive mechanism of the forme cylinders (03, 17) and the drive mechanism of the transfer cylinder (04, 16) of two pairs (02, 14), which are arranged next to each other in respect to a circumference of the associated satellite cylinder, are fixedly mechanically coupled with each other, characterized in that during the printing process the two coupled pairs (02, 14) are driven by a common drive motor (06), together with which they form a drive assembly (33), and that this drive assembly (33) can be switchably mechanically coupled with the associated satellite cylinder (08) via a connector (12).
