Central support arrangement for printing systems

Abstract

A versatile system for printing on flexible sheets of material includes a center roller driving at least two backing rollers with an endless flexible blanket sleeve enveloping the backing rollers and urging the backing rollers inwardly against the center roller. The backing rollers are independently adjustable in selective positions about the circumference of the center roller and have selective diameter sizes independent of the other backing rollers. Feed and take up means provide a sheet of material around the rollers and blanket sleeve and printing devices are mounted against the sheet for printing thereon. The printing devices may be mounted at flexible web portions of the sheet and sleeve spaced from the backing rollers for printing on the flexible portion stretched between the rollers. The feed and take-up portions and roller and printing portions are separable to permit different roller and printing systems to be utilized while each system may include various printing devices such as rollers or stationary units.
