<p>It can be applied to printing cylinders comprising a shaft (51) on which a liner (52, 53) is mounted, means for fastening such liner on the shaft and pneumatic means to facilitate that the liner slides on the shaft. The device comprises a chamber (2) delimited by a wall (1a) fastened on or forming a part of a end of the liner and by surfaces which pertain to the shaft (51), means (50, 60) being provided to introduce compressed air in such chamber (2) and the arrangement relative to an internal surface of such wall (1a) and the said surfaces pertaining to the shaft (51) being such that the pressure which impinges on such surfaces generates removal strength components in the sliding direction and in opposite senses on such shaft and on such liner, respectively. <IMAGE></p> |
