Abstract

Variable-format web-fed offset printing machine having printing-unit cylinders comprising core cylinders to which compressed air can be applied and onto which intermediate sleeves can be pushed axially and shrunk on radially. Each intermediate sleeve includes a carrier layer whose inner face rests on the core cylinder, a compressible intermediate layer, a transition layer, and a variable-thickness bridging layer, which ends with a covering layer to which a further surface like a printing plate or a rubber blanket can be fitted.
