Abstract: Use of a rigid roller obtainable by a method comprising the steps: providing a roller core; applying a liquid coating composition based on a polyimide or polyamide-imide prepolymer with a layer thickness of 1 to 1000 ?m; solidifying the liquid coating composition on the roller core; as an distributor or Rilsan roller.

Abstract: The invention relates to a method for repairing a printing roller having a roller base body made (10) of plastic or a plastic compound material. Into the two end regions (14) of the roller base body, bearing support members (16) are inserted, said bearing support members being connected to the roller base body (10) by bonding. Due to the occurrence of high stresses during the operation of the printing roller, inner surfaces (24) of the bearing support members (16) may be damaged. The damaged bearing support members (16) will be milled on their inner surfaces (24). Then, a respective sleeve (32,44) is inserted into the bearing support members (16). The inner surfaces (36) of the sleeves (32,44) serve for taking up outer bearing rings (26) of the roller bearings supporting the printing roller. The invention further relates to a printing roller with inserted sleeve (32,44).

Abstract: A roller consisting of a metal core (1) and a soft elastomeric coating (2) and two rigid necks (3, 3′) has between said metal core (1) and said elastomeric coating (2) a rigid conical layer (4) of a rigid elastomer permanently bound to the metal core, and a rigid, conical, slightly expandable support (5) which is permanently bound to the soft elastomeric layer (2), wherein a space allowing a lateral displacement of the support on the rigid elastomeric layer (4) can be generated between the rigid elastomeric layer (4) and the support (5) by compressed air flowing through. During the blowing through of air, an air cushion forms which allows to laterally displace and position the sleeve on the metal core. After the blowing of the air is stopped, the sleeve contracts and tightly embraces the conical rigid elastomeric layer (4).

Abstract: The coated roller with permanent identification is characterized in that an externally inducible microtransmitter with a multidigit alphanumerical code is attached at or in the roller core which microtransmitter is not nondestructively removable. Said microtransmitter is preferably resistant to temperatures of up to at least 180.degree. C. and to chemicals.

Abstract: The method for removing used elastomeric covers from rollers is performed by approaching a rotating cutter head having a number of cutting tools mounted on an indexable insert holder from one end of the cover of the rotating roller to close to the roller core, and moving said cutter head along the rotating roller to the other end of the cover, the circumferential velocities of the cutting tools being from 15 to 70 m/s, preferably from 40 to 50 m/s. For elastomers of up to about 90 Shore A, annular cutting tools are used.

Abstract: The fluid container for shipping and storing fluids, especially liquid detergents for the printing trade, consists of an approximately rectangular recipient having rounded corners, a screw cap, an aerator pipe leading to the interior of the container, and a carrying handle situated at the upper part of the container, the interior of which has a hollow design, the handle at the same time serving as the aerator pipe.

Abstract: A process for the surface treatment of elastomers forming the outermost layer of a coated rotationally symmetrical body, the outer layer having a hardness of from 10 Shore A to 100 Shore D, wherein a high cycle motor spindle bearing a high-speed cutter head with cutting tips is brought into contact with the work material.

Abstract: The process for grinding a rotating rubber roll by means of a grinding wheel is taking place in such a way that at least during the last grinding cut a rotating plugging roll is applied to the grinding wheel which plugging roll has a harder rubber than the rubber roll.
