VARIABLE PRINTING MACHINE

摘要

PROBLEM TO BE SOLVED: To enable variable printing without generating slackening and flapping even when a material to be printed is a plastic film or a thin material, and furthermore, without generating damaging and staining by printing on the surface of the material to be printed.

SOLUTION: Impression cylinders 6 of printing units 3a-3d arranged between a pair of delivering rollers 1 and 2 are made to be synchronously rotatable to a pair of the delivering rollers. Guide rollers 12a and 12b for winding a material to be printed passing through between a printing cylinder and the impression cylinder on the impression cylinder over a specified winding angle are arranged on at least one of the upstream side and the downstream side of each impression cylinder, and these guide rollers are synchronously rotated at the same peripheral speed as that of the impression cylinder.
