Abstract
The disclosure relates to a method and an apparatus in a roller printing unit for locking the rollers in associated bearing housings in connection with the movement of the rollers from the open position to the working position. The movement of the rollers (2, 3) in relation to the frame of the printing unit is utilised in order, during the movement operation, to mechanically manoeuvre locking devices (14) at the bearing housings (5) of the rollers between open and closed position.
Claims9
In a roller printing unit, a method of locking rollers in associated bearing housings comprising:
- moving the rollers translationally in relation to the printing unit from an open position to a working position, and mechanically transferring said movement to maneuver said locking devices at the bearing housings of the rollers between open and closed positions.
A locking apparatus for rollers in a printing unit of the type in which a number of cooperating rollers suspended in a frame are movable between a working position and an open position in which the rollers are located a distance from one another and from associated bearing housings, wherein the associated bearing housings include locking devices for the rollers, said locking devices being disposed to cooperate with maneuvering devices mounted on the frame such that, in the working position of the rollers, the locking devices are located in a closed position, in the open position of the rollers, the locking devices are located in an open position, and translational movement of the rollers in relation to the frame maneuvers the locking devices via the maneuvering device.
