Support for printing cylinder - consists of shaft with modulus of elasticity equal or higher than modulus of elasticity of cylinder

摘要

The cylinder (1) is for a rotary printing machine. It is supported by a steel shaft (2) running along its whole length, and incorporating bearing surfaces (3,4) at either end. There are discs (7,8) at the ends of the cylinder, connecting it to the shaft. A flat on the shaft engages with a corresponding part (9) of the internal structure of the cylinder, to drive it. Struts inside the printing surface of the cylinder engage the shaft to help stiffen the cylinder. The modulus of elasticity of the cylinder is equal or less than the modulus of elasticity of the shaft. USE/ADVANTAGE - Support for printing cylinder with vibration damping and min. distortion.
