Abstract

PURPOSE: To obtain a printed surface of good quality and uniform tint, by allowing a chrome roller of a Dahlgren damping system to swing in its axial direction.
CONSTITUTION: When a water source roller 5 is turned, pinions 15 and 16 of a chrome roller 4 are turned by pinions 13 and 14 on the both sides of a rotary shaft 12, and a roller main body 8 and a roller supporting shaft 9 are turned in the same direction. As rotating speed of the pinion 15 is larger than that of the pinion 16, the roller main body 8 is turned faster than the roller supporting shaft 9. And therefore, in the relationship of engagement between a roller 20, which turns together with the roller main body 8 as a continuous body, and a grooved cam 17, which turns together with the roller supporting shaft 9 as a continuous body, the roller 20 moves forward in a cam groove 18 by a difference in the rotating speed, and the roller main 8 is displaced in the axial direction by amount of displacement of the cam groove 18, and the roller main body 8 is reciprocated in the axial direction within a range of amount of the displacement. As transfer of ink is unified by this reciprocating motion, it is possible to obtain a printed surface of good quality and uniform tint.
