ABSTRACT:
To modify an existing printing press from its original length/cut off to a different cut off, a sub-frame may be mounted on an existing frame of a printing press. The sub-frame permits the relocation of bearing supports for various printing cylinders, such as, for example, the plate cylinders and blanket cylinders. In addition to mounting the sub-frame on the existing frame, new plate and blanket cylinders having different sizes than the plate and blanket cylinders used in the existing printing press may be mounted in the sub-frame to provide different printing lengths/cut offs. Suitable sleeves, such as the eccentric mounting sleeves may be provided as necessary in order to mount the cylinders to the sub-frame.
