Abstract: A backing plate unit for a rotary grinding machine includes a backing plate with a front face for mounting a grinding disc and a back face opposite the front face, a drive shaft that can be attached to the tool adaptor of the rotary grinding machine, and a suction hood that is rotatably fixed to the drive shaft. The backing plate 10 includes suction openings that penetrate the backing plate so that the suction hood 30 vacuums dust through the backing plate to the back face of the backing plate.

Abstract: Apparatus and Method for manufacturing a cleaning body 1, consisting of a first plate 10 made of melamine resin foam and a second plate 20 made of melamine resin foam, wherein the first plate 10 comprises at a first side 12 thereof a burled surface and the second plate 20 comprises at a first side 22 thereof a burled surface, wherein the first plate 10 is adhered at the burled surface of the first side 12 by means of at least one adhesive layer 30 with the burled surface of the first side 22 of the second plate 20.

Abstract: A method and device for changing software in a first memory area in a control unit for controlling operational sequences, the execution of old software parts being replaced by the execution of new software parts and the old software parts being written into the first memory area, the new software parts being written into a second memory area and, due to a first branching in the first memory area, instead of the old software parts being executed in the first memory area, the new software parts are executed in the second memory area, the system, following the execution of the new software parts, branching back again into the first memory area via a second branching in the second memory area and the execution of the other software distinct from the old software parts being continued in the first memory area, the old software parts remaining in the first memory area.

Abstract: An abrasive belt for a belt grinding machine has a support layer, an intermediate layer connected to the support layer, and an abrasive layer connected to the intermediate layer. The support layer transmits a drive output of the belt grinding machine onto the abrasive layer. The abrasive layer allows flow of grinding particles through the abrasive layer. The intermediate layer also allows flow of the grinding particles through the intermediate layer, and the support layer allows flow of the grinding particles through the support layer.
