摘要:
A forme cylinder is supported and adjusted in a printing group of a rotary printing press, which group includes a transfer cylinder and a counter-pressure cylinder, which two cylinders include interacting support elements. The forme cylinder does not include a support element which interacts with the transfer cylinder. The forme cylinder has a shaft distance that can be adjusted during printing to adjust a contact pressure between the forme cylinder and the transfer cylinder. The forme cylinder may be covered with a waterless printing forme. The contact pressure between the forme cylinder and the transfer cylinder can be adjusted to a property, such as the compressibility, of the waterless printing forme.
摘要:
A printing machine has at least one printing unit on which a web of material, which is to be imprinted, is imprinted by offset printing in a variable cut length. A folder is mounted downstream, in the direction of travel of the printed web, of the at least one printing unit. The folder may be located directly or indirectly from the at least one printing unit and has a variable cut length.

A printing blanket assembly for a blanket cylinder of a rotary printing press includes a dimensionally stable support plate, and a printing blanket fastened to the outside of the support plate. A leading end of the support plate and a trailing end of the support plate are fastened to the blanket cylinder by the provision of an angled or beveled, printing blanket free end. A filler is provided between the beveled end of the support plate and the inner edge of the leading and trailing ends of the printing blanket.
摘要:
The invention relates to a printing blanket assembly for a blanket cylinder of a rotary printing press. The printing blanket assembly comprises a dimensionally stable support plate (02, 18) with two ends, one of which is the forward end and the other one is the trailing end with respect to the rotation of the blanket cylinder, these ends being fastened to the blanket cylinder with folded, printing-blanket free limbs (21, 22). The assembly further comprises a printing blanket (03, 19), fastened to the outside of the support plate (02, 18) and having a forward end (12, 31) and a trailing end (11, 32). Said printing blanket assembly allows for perfect printing also in the area of a gap between the limbs (21, 22) and can be produced in a simple manner. For this purpose, both ends (11, 12; 31, 32) of the printing blanket (03, 19) project beyond the bevelled edge (08, 09; 27, 28) of the pertaining limbs (04, 06; 21, 22) of the support plate (02, 18) and one support element (13, 14; 34, 36) for supporting said projection is disposed between the bevelled edge (08, 09; 27, 28) and the inside of the printing blanket (03, 19).
