摘要

The cylinder (01) has a lateral area, a bale and a channel that is located in the bale, where the channel has a front edge and a rear edge. The front and rear edges form a gap that penetrates the lateral area. An insertion piece (20) is inserted in the channel, by which the rear edge is covered and is inserted by a guiding surface that is formed by the insertion piece. An independent claim is also included for a method for retrofitting a cylinder for a printing unit.
