Abstract
A carrier sleeve for supporting flexible printing plates, the sleeve having a limited circumferential resilience, whereby when subjected to air jets emitted from the apertures in the wall of a printing cylinder, the sleeve is dilated to facilitate the application of the sleeve to the cylinder or its removal therefrom. The sleeve is constituted by three interlaminated layers, each formed by a helix of synthetic plastic tape. Two layers of the sleeve are wound at the same helix angle but are phase displaced relative to each other, whereby the air gap between the convolutions of one layer is bridged by the convolutions of the other, thereby sealing the gap and rendering the sleeve impermeable to air. The remaining layer is wound at an angle opposed to the helix angle of the other two, thereby strengthening and rigidifying the structure of the sleeve.
