ABSTRACT:
A printing unit for a web-fed rotary printing press comprises a housing defining a first side wall in which a drive mechanism is mounted and a second side wall in which a locking mechanism is mounted. A blanket cylinder including a plurality of holes extending axially therethrough, and being releasably mounted between the first and second side walls includes an endless tubular printing blanket mounted around an external surface thereof. A first end-cap affixed to a first end portion of the blanket cylinder is drivingly coupleable to the drive mechanism so that torque generated by the drive mechanism is transmitted via the first end-cap to the blanket cylinder to rotate the blanket cylinder about the axis. A second end-cap is selectively coupleable to the locking mechanism so that, when the locking mechanism is in a locking configuration, the blanket cylinder is constrained to rotate about the axis and, when the locking mechanism is in a second release position, the second end portion of the blanket cylinder is free from constraint and the blanket cylinder may be removed from the housing.
