| 摘要 |
A printing machine color assembly presenting a main or cliché-carrying cylinder ( 2 ) and an interlocking or screened cylinder ( 3 ), each carried at its hubs ( 2 a , 2 b ; 3 a , 3 b) by first ( 4 a ; 5 a-operator side) and second ( 4 b ; 5 b-motor side) slidable supports positioned on different sides of the printing machine and parallel displaceable independently from one another. The first support ( 5 a) of at least said main cylinder ( 2 ) is detachable from the respective hub ( 2 a) to cantileverwise position the main cylinder ( 2 ) on the second support ( 5 b) thereby carrying out the sleeve replacement on the main cylinder ( 2 ). At least one auxiliary supporting means ( 17 ) at the second support ( 5 b) of at least the main cylinder ( 2 ) is designed to engage with, and assist in supporting, it when cantileverwise positioned for replacing a sleeve.
