    摘要: The present invention provides methods and apparatuses for forming a mounting flange on a printing plate comprising first and second portions having an arcuate portion therebetween and defining a mounting flange angle. A bending device comprising a forming surface having a radius that is less than a desired radius for the arcuate portion can be used to form the arcuate portion in accordance with the present invention. This can be done by forming the arcuate portion to have a plurality of spaced apart bends that cooperatively define the arcuate portion.
