Abstract

Device for clamping a blanket on the blanket cylinder of rotary printing machines having an outer cylindrical surface formed with a slot extending parallel to the axis of the cylinder and widening radially inwardly, the slot accommodating at the radially inwardly widened region thereof two rotatable clamping spindles for clamping the blanket, each of the clamping spindles being formed with a longitudinal groove for receiving respective ends of the blanket therein, the respective ends of the blanket having sheathing thereon, including at least one support rod disposed in the widened region of the slot between the outer cylindrical surface of the cylinder and the two clamping spindles, the support rod extending parallel to and being slightly spaced from the clamping spindles, the support rod, during clamping of the blanket, being in engagement with a part of the blanket adjacent the sheathing and forming an angle in the blanket part so as to force the sheathing fully into the respective longitudinal groove and prevent it from slipping out of the groove.
