  • Patent number: 6745692
    Abstract: 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.
