Abstract: Apparatus for making rod-shaped tobacco products with a filter that includes a tobacco stick delivery device, a filter delivery device, a covering paper delivery device, a cigarette making device, a cigarette testing device, and a cigarette dispensing device. All the devices, in which each device includes at least one drum, are arranged to form a drum course. A drive element is structured and arranged to drive at least some of the drums of the drum course in positional synchronization with the transport of the rod-shaped tobacco products, and a drum unit is composed of at least one drum, which is not one of the at least some drums, and a bearing and control flange. At least one separate additional drive element is structured and arranged to drive the at least one drum, and a drive unit is composed of the separate drive element and the drum unit. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A device for displacing rod-shaped objects used in the tobacco-processing industry in a direction of the longitudinal axes of the rod-shaped objects includes a revolving conveyor having receptacles each for receiving a plurality of the rod-shaped objects in an axially aligned formation, the rod-shaped objects presenting at least one exposed frontal face. At least one revolving pressing ring is arranged for pressing against the at least one frontal face of the objects in a displacement area, the pressing ring having a spring-elastic material of a silicon material, rubber-elastic plastic material and/or a metallic material. At least one actuating element is arranged in the displacement area for a spring-elastic pressing of the pressing ring against the exposed frontal face objects.

Abstract: A mounting for a grinding wheel serves to connect the grinding wheel to the tool spindle of a grinding machine has a holding member for the grinding wheel and a threaded fastener which separably secures the holding member to the spindle. The fastener is surrounded by an annular retaining portion of a tensioning device which has elastic prongs at one side and a compression spring at the other side of the retaining portion. The prongs are clamped between the holding member and the head of the fastener in response to rotation of the fastener in a direction to couple the holding member to the spindle, and the compression spring then reacts against the spindle so that the tensioning device maintains the fastener in form- and force-locking engagement with the holding device.
