Abstract
A rotary punch for punching envelope blanks from moving webs of paper or like or for making shaped cuts from prepared envelope blanks has a backup roll which bears on a cutter roll. The punch is characterized by the provision of intermediate bearings with an adjustable member therebetween. This precludes unwanted movements in the bearings between the two rolls due to varying cutting and out-of-balance forces, the adjustable member making it possible to correct the between-axes distance to suit cutter wear.
