Abstract
PURPOSE: To make uniform an ink feed and eliminate an unevenness of printing density and printing concentration by forming a plate barrel consisting of an internal cylinder equipped with an auxiliary chamber and an external cylinder with a meshlike element, etc. under a special constitution and supplying ink through the intermediary of the auxiliary chamber.
CONSTITUTION: An ink is pressure-fed to a distributing chamber 21 through the intermediary of an injection joint 16 and induction holes 17a, 17b by means of a pump 15 with a plate barrel idling without a load. In the meantime, an internal cylinder 1 with an auxiliary chamber 25 and an external chamber 3 consisting of a meshlike element and a screen 4 are caused to rotate while being deviated from each other and then a rotary twisted cylinder 24 is turned. Through this rotation and an ink injection pressure, the ink is squeezed into between 36 a cylinder 24 and the distributing chamber 21, thus uniformly feeding it over the entire width of the internal cylinder to be filled into the auxiliary chamber 25. As the internal cylinder is rotated slightly behind the external cylinder, the ink permeates into the screen 4 of the external cylinder 3 to be allowed uniformly on to the surface. Under this condition, paper feed takes place and printing is performed between the plate barrel and the pressure barrel 26.
