<p>A cutout (11) is made in a web (7) from above, a locking element (12) being inserted into said cutout. The cutout (11) connects an upper outer side of the web (7) to a transverse bore (9) in an arm (14) of the web (7). In the assembled state, the web (7) is inserted into a cutout (10) of the cylinder pocket (4) and connected by a transverse pin (6). In order to secure the transverse pin (6) against longitudinal displacement in the cylinder pocket (4), said transverse pin (6) exhibits an encircling groove (14) into which the locking element (12) engages from above. In order to exchange the web (7), the rotary cylinder (1) is rotated about its longitudinal axis such that the cylinder pocket (4) is at the top. Upon rotation, the locking element (12) moves downwards due to its gravitational force and releases the transverse pin (6). The rotary cylinder (1) according to the invention can be lengthened or shortened on site, without reducing the security, by exchanging the web (7). <IMAGE></p> |
