ABSTRACT:
A web printing press is provided with a plurality of printing units, each including a plate cylinder, an idling impression cylinder, and web metering roller supported between the side walls of a frame. A motor-driven primary line shaft is supported on the frame and extends along one of the side walls, and a first gearbox is connected between the primary line shaft and the plate cylinder of each unit for transmitting rotation of the primary line shaft to the plate cylinder. A second gearbox is connected between the primary line shaft and the web metering roller of each unit for transmitting rotation of the primary line shaft to the web metering roller. A motor-driven secondary line shaft is supported on the frame and extends along one of the side walls adjacent the primary line shaft, and the second gearbox of each printing unit includes gearing connected to the secondary line shaft for trimming the speed of the web metering roller relative to the speed of the primary line shaft upon rotation of the secondary line shaft.
