A transfer cylinder sleeve is provided for an offset printing machine including an inner carrier layer, a compressible layer and a covering layer, where at least one of the layers has a joint or a gap and provided that when a joint or a gap is used in the covering layer, then the transfer cylinder sleeve is applied to a transfer cylinder in register so that the joint in the covering layer rests opposite a tension channel of a plate cylinder during rolling contact of the transfer cylinder with the plate cylinder. Optionally, a non-stretchable layer is provided between the compressible layer and the covering layer, or alternatively, a non-stretchable material is provided in the compressible layer itself.

What is claimed is: 1. A transfer cylinder sleeve in an offset printing machine, the offset printing machine having a transfer cylinder and a plate cylinder, the plate cylinder having a tension channel, wherein the transfer cylinder sleeve comprises: an inner carrier layer mountable onto the transfer cylinder, said carrier layer being expandable by compressed air; a compressible layer mounted on said carrier layer, said compressible layer defining air spaces therein; a cover layer being compressible and mounted on said compressible layer, said cover layer being less compressible than the compressible layer, one of said inner carrier layer, said compressible layer, and said cover layer comprising a joint or gap along a longitudinal length thereof; and a registration device arranged on an inner surface of said carrier layer engagable with the transfer cylinder, whereby said carrier layer is fixable to the transfer cylinder at a register position and said joint is alignable to roll on the tension channel of the plate cylinder. 2. The transfer sleeve according to claim 1, in combination with the transfer cylinder of the offset printing machine, wherein said transfer cylinder comprises means for receiving said registration device, wherein said registration device and said means for receiving form a positive connection, thereby fixing the transfer sleeve in the register position. 3. The transfer sleeve of claim 1, wherein said cover layer defines air spaces. 4. The transfer sleeve of claim 1, wherein said carrier layer is metal. 5. The transfer sleeve of claim 4, wherein said carrier layer has a weld seam joint, wherein each of said carrier layer, said compressible layer, and said cover layer defines a joint formed by mutually abutting ends of said carrier layer, said compressible layer, and said cover layer, respectively. 6. The transfer sleeve of claim 5, wherein each joint of said carrier layer, said compressible layer, and said cover layer is an adhesive joint. 7. The transfer sleeve of claim 1, further comprising a non-stretchable layer arranged between said compressible layer and said cover layer. 8. A transfer sleeve in an offset printing machine, the offset printing machine having a transfer cylinder and a plate cylinder, the plate cylinder having a tension channel, wherein the transfer cylinder sleeve comprises: an inner carrier layer mountable onto the transfer cylinder, said carrier layer being expandable by compressed air; a compressible layer mounted on said carrier layer, said compressible layer defining air spaces therein; a cover layer being compressible and mounted on said compressible layer, one of said inner carrier layer, said compressible layer, and said cover layer comprising a joint or gap along a longitudinal length thereof, wherein said cover layer comprises only a single layer having a radially inner region and a radially outer region, wherein said radially inner region defines air spaces therein and said radially outer region comprises an elastic part without air spaces. 9. The transfer sleeve of claim 8, further comprising a registration device arranged on an inner surface of said carrier layer engagable with the transfer cylinder, whereby said carrier layer is fixable to the transfer cylinder at a register position and said joint is alignable to roll on the tension channel of the plate cylinder. 10. The transfer sleeve of claim 8, wherein said cover layer is less compressible than said compressible layer.
