Apparatus for supplying washing solution in printing press

Abstract

Abstract PURPOSE:To make it possible to also use a solvent applying roller as a dust removing roller at the time of printing, by using a material having a stickiness property but not having the compatibility with ink as the material of the solvent applying roller. CONSTITUTION:When a material having stickiness but having no affinity with ink such as silicone rubber is used as the material of a solvent-applying roller 1803, the roller 1803 is intermittently or always contacted with a blanket cylinder 2 corresponding to the amount of the dust on the cylinder 2 during printing. The dust such as the paper powder adhered to the surface of the cylinder 2 during printing is adsorbed by the surface of the roller 1803 by utilizing the stickiness of silicone rubber. The above-mentioned dust is gradually recovered in a liquid tank 1805 through a scoop-up roller 1804 at the time of the washing of the cylinder 2. Therefore, the surface of the roller 1803 is protected from a cover of dust. The transfer of the residual ink from the surface of the cylinder 2 during washing can be effectively prevented because the material low in the compatibility with ink is used.
