Abstract: A coating device for applying a coating agent to the surface of a workpiece. The coating device includes a frame with a workpiece receptacle, a coating agent source and a rotary unit which is rotatable in relation to the frame. The rotary unit has a pump and a plurality of spray units, with the pump on the suction side being connected to the coating agent source by a fluid-conducting rotary joint connection. The rotary unit has a pneumatic valve device, and the spray units have in each case one compressed air controlled valve for controlling the delivery of coating agent. The inlet side of the valve is connected to the compressed air source by a fluid-conducting rotary feedthrough, which simplifies the overall construction of the coating device by providing a pneumatic connection between the compressed air source and the rotary unit that is independent of the rotation angle.

Abstract: A cleaning device for a residue contaminated conveyor belt includes a roller arranged below the conveyor belt such that the lateral surface thereof contacts a lower strand of the conveyor belt, and a cleaning belt is arranged below the roller. The lateral surface of the roller contacts an upper strand of the cleaning belt, which is tilted relative to a main conveying direction at the upper strand relative to a longitudinal roller axis. A dispensing device on and/or above the cleaning belt feeds a solvent thereon. The dispensing device and the cleaning belt are relatively arranged such that the solvent from the cleaning belt is conveyed by a conveying movement of the cleaning belt into a region in which the cleaning belt contacts the roller, which via a rotational movement, at least partially picks up the solvent located on the cleaning belt and dispenses it onto the conveyor belt.

The rotary unit has a pump and a plurality of spray units, the pump on the suction side being connected to the coating agent source by a fluid-conducting rotary joint connection, and on the pressure side being connected to the spray units. The rotary unit has a pneumatic valve device, and the spray units have in each case one compressed air controlled valve for controlling the delivery of coating agent. The valve on the inlet side is connected to the compressed air source by a fluid-conducting rotary feedthrough and on the exhaust air side is connected to the compressed air controlled valves of the spray units.

Abstract: A heated roll with a circular cylindrical casing tube 1 made from thermally conductive metal, which is closed at its end faces with caps 2, 3. One or more electric heating mats 8 are arranged inside the casing tube 1. By at least one connection pin 5, which is arranged at one cap 2, connection cables 11 are guided for supplying the heating mats 8 with electric power. Annular brushing bodies 7 are fastened at the connection pin 5 and serve for the electric contacting of the connection cables 11. A tensioning device 9, 14, 15 is arranged inside the casing tube 1, which presses the heating mats 8 permanently against the interior surface of the casing tube 1.
