A mandrel-locking unit for a rotary printing machine has a mandrel-mounting element that surrounds print roller mandrels in an inner bearing for mounting a mandrel-supporting surface and into which the mandrel-mounting element can be slid such that the mandrel-supporting surface is released by the sliding movement. The unit has a pressurizing medium cylinder that provides the force required for the sliding movement and a piston, which delimits a pressure chamber of the pressurizing medium cylinder at a boundary surface and which is in contact with the mandrel-mounting element at a connecting point and conveys to the mandrel mounting element the pressure required for the sliding movement. A feature of the unit is that the distance between the boundary surface and the connecting point is smaller than the maximum stroke of the piston in the pressurizing medium cylinder.

Mandrel locking unit for printing roller mandrels in a rotary printing machine

A printing unit of a printing machine has at least one ink transfer roller, and at least one bearing block movable relative to the printing unit frame, in which, in the printing position, one end of the ink transfer roller can be supported, and which releases that end of the ink transfer roller in its released position. The unit has a blade chamber holder which carries at least one blade chamber that can be adjusted on the ink transfer roller and which is connected rotatably and displaceably with the bearing block in the printing position. The blade chamber holder is supported permanently on the bearing block by support elements on the bearing block.
