摘要： The invention concerns a sleeve with a multiple layer structure for printing presses with king rolls configured as pneumatic cylinders; in particular a sleeve for the flexographic printing process, with an inner tube of reversibly expandable plastic material, whose internal diameter is smaller than the king roll diameter, with an elastic compressible intermediate layer that accommodates the radial expansion of the inner tube during installation, and with an outer layer. The invention concerns also a manufacture procedure for sleeves of this type. The sleeve in accordance with the invention is characterised by a support structure in the sleeve construction between inner tube and outer layer, which completely penetrates the compressible intermediate layer in at least one location in the radial direction and stabilises the outer layer relative to the inner tube in the circumferential direction and/or the radial direction. As a result of the partial bridging of the compressible intermediate layer this is offloaded from forces in the direction of rotation. In this manner the possibility that vibration stripes can appear in the print image is avoided.

摘要： A sleeve (10) for flexographic printing includes a sleeve body (2) made of an at least partially non-electroconductive material, which within its inside (4) is mountable on an electroconductive king roll on the outer wall of the roll, of a printing press, the king roll being designed as an air cylinder, and exhibiting at least one contact zone with the king roll. The sleeve exhibits an electroconductive surface (6), which is connected to the contact zone via at least one electroconductive element (20) provided in the sleeve body (2) for diverting electrostatic charges into the outer wall of the roll of the king roll. The sleeve is therefore given an electroconductive structure, through which the unavoidable electrostatic charges in printing presses with a plurality of printing couples are diverted via the king roll before it reaches a scale that would suffice for a discharge, ignition, or deflagration of the solvents used in the printing.

摘要： The invention relates to a sleeve for mounting on carrier cylinders of printing machines, with two flange rings 11, 12 on the ends, on which a cylindrical outer sleeve wall 20 and an inner sleeve wall 30 are supported at a distance from each other. In order to create a sleeve, more particularly an adapter sleeve, that can be easily mounted on and removed from carrier cylinders, is cost-effective to produce, and with a comparatively low weight allows extremely high printing qualities, it is envisaged in accordance with the invention that the external sleeve wall 20 comprises a fibre composite material with at least one layer of a carbon fibres-nonwoven sheet 21 and that between the two flange rings 11, 12 at least one support ring 40, 40A is provided that supports the outer sleeve wall 20, vis-à-vis the inner sleeve wall 30.
