給水エア吹き装置。 In a water supply air blowing device of a lithographic printing press that blows air around the non-printing areas at both ends of the printing plate, a pair of air blowing pipes extending in the width direction of the machine are provided in close proximity to each non-printing area on both sides to which the air is blown. The air blowing tube has a double-tube structure consisting of a fixed outer tube and a rotatable inner tube connected to an air source. A plurality of air blowing holes arranged in parallel by the length of the non-printing area for paper are bored, and the inner tube has a plurality of rows of air blowing holes corresponding to the air blowing holes of the outer tube by rotation thereof. The number of air holes in each row is decreased in a stepwise manner outwards, from the same number as the number of air holes in the outer pipe to approximately 1 each time the row changes in the circumferential direction. A water supply air blowing device for a lithographic printing machine characterized by the following settings.
