The invention relates to a device for the fastening and positional changing of a cylinder covering on a printing-unit cylinder with axially parallel groove. At least one tensioning spindle is provided for the tensioning of a cylinder covering, with a toothed shaft being in engagement with teeth on the tensioning spindles, with the shaft comprising, on the part facing the groove opening, a locator for an adjusting tool. Tensioning spindles (3, 4) are movable through the intermediary of an actuating drive (6, 9; 18), held on the end face of a printing-unit cylinder (1), in such a manner that both a cylinder covering (29) is tensionable in the circumferential direction simultaneously at its front and rear edges and also the position of the cylinder covering (29) on the printing-unit cylinder (1) is adjustable in defined manner through the intermediary of actuators (16, 19, 20, 22, 23) on at least one of the tensioning spindles (3, 4).
