ABSTRACT:
To prevent center sag, or bowing of printing cylinders, and thus uneven printing throughout the axial length thereof, extension struts are connected to stub shafts at the ends of the cylinders, the struts being connected together to form a closed, rectangular or square frame in which the individual lengths of the struts are adjustable to thereby provide individually adjusted forces to the ends of the stub shafts and counteract sag or bow of the cylinders.
