Abstract: A sheet-processing machine includes a turning device. Sheets can be conveyed, by a sheet conveyor system, from a sheet guide cylinder in the turning device, and can be conveyed in a sheet conveyor direction on a sheet conveyor path. A sheet guide element is provided beneath or along the sheet conveyor path. A deionization device is assigned to the sheet guide element. The deionization device can provide positive and negative ions.

Abstract: The invention relates to a device for supporting the body of a person (2). Said device comprises a seating surface (3), a back support (4) and a moveable lordosis support (11). A therapeutically, particularly effective relief of the strain on the lumbar column (17) can be produced by virtue of the fact that an additional lateral support (10) for the body engages in the region of the Musculus latissimus dorsi of the person (2) and by virtue of the fact that the seating surface (3) can be embodied in such a manner that it can be lowered in relation to the back support (4).

Abstract: The invention relates to a wheel (1; 1a, 1b) for a piece of sports equipment, especially for grass skiing, comprising a rim (2), a tire (3) that is fastened to the rim (2) and is provided with a tread (9), and at least one support element (6) for the tire (3), which is embodied in a resilient manner. The riding behavior can be made to largely match that of alpine skis due to the fact that the support element extends in a curved manner from a first bearing section (5) to a second bearing section (5) and supports the tire (3) essentially along the entire distance of the cross-section thereof while the tire (3) has a multilayer structure and is provided with a layer (10) that is elastic in the direction of the thickness thereof.
