PROBLEM TO BE SOLVED: To make the rubbing quantity by bristle materials at the time of brushing equal and to make the removal of unnecessary photosensitive material layers by brushing uniform in the removal of the photosensitive layers of photosensitive planographic printing plates. SOLUTION: If the pressing force exerted on a photopolymer plate 102 from a brushing member 142 is assumed to be constant across a transverse direction, the largest pressing force is exerted at the central part in the transverse direction of the photopolymer plate 102 by the influence of the arcuate shape of the front surface part 144A of a receiving member 144. The curving of the brushing member 142 to an outer side is, however, resulted at the time of applying the pressing force and the pressing force is smallest in the central part of the transverse direction of the photopolymer plate 102. If such things are coordinated, the differences in the pressing force are offset and eventually the uniform pressing force may be exerted over the entire area in the transverse direction of the photopolymer plate 102. |
