• the ends are bent / folded (e.g. in the area of its leading end by approximately 45 ° and in the area of its trailing end by approximately 135 ° or by an intermediate angle of 45 °).
• These ends extend through the opening 437 of a channel extending axially over the entire width to be used of the transfer cylinder 303, which also, for example, also has a locking device 438, clamping and / or tensioning device 438, in particular a clamping device shown essentially in that of the forme cylinder 304 in FIG. 9 410 accordingly.
• the reference numerals of the forme cylinder 304 have been added to the corresponding ones of the transfer cylinder 303 in FIG. 9. 8 and 9, for example, corresponds to the dimensionally stable carrier layer of the elevator 436, which is designed as a metal printing blanket 436, an elastic layer on the effective outer surface not being shown in FIG. 9, however.
• the opening 437 to the channel preferably has a width of 1 to 5 mm, in particular less than or equal to 3 mm, in the region of the circumferential direction of the cylinder 304.
• the clamping device 438 is advantageously pneumatically operable, for. B. as one or more pneumatically actuated lever 442, which are biased in the closed state by means of spring force against the trailing end reaching into the channel.
• a hose 444 which can be pressurized with pressure medium can preferably be used as the actuating means 444.
• the transfer cylinder 303 preferably carries a single elevator 436 designed as a printing blanket 436 which, regardless of the presence of a washing device 434 or the special design of a clamping device 438, extends essentially over the entire width of the web B to be printed; B 'and essentially (except for a joint or a channel opening) extends around the entire circumference of the transfer cylinder 303, and which is dimensioned accordingly.
