Method and device for slackening a covering of a cylinder of a printing machine.

摘要

The releasing process releases at least one tympan from a cylinder (02) of a printing press, where it is locked in a channel (08) of the jacket surface (06). Compressed air (36) is supplied from outside the cylinder to at least one end of the tympan on both its end faces, from the side, to the underside of the tympan to release its suspension arm from the aperture.
