Abstract
In a multi-color printing machine, a skew or slant of a picture to be printed is corrected by cocking, namely, swinging a paper-feed cylinder relative to a base impression cylinder by a unique but simple cocking mechanisms. The cocking mechanism includes a shaft holder which holds one end portion of the shaft of the paper-feed cylinder and which is pivotable about an eccentric position disposed on an imaginary line extending between central axes of the paper-feed cylinder and the base impression cylinder. The shaft holder is connected at another end thereof to an operating shaft via screw means which converts rotation of the operating shaft into the pivotal movement of the shaft holder.
