Machine for producing or machining or processing a sheet-like material web

Machine (1) with a support structure (10), a vertical support assembly (15, 20), comprising two separate support portions which are arranged one above the other, so that it has a lower support portion (16, 21) and a supported thereon upper support portion (17, 22) form, and a magnet assembly (30) having at least first and second magnetic devices, each of which two magnetic units (41, 42; 51, 52) which are arranged on mutually facing ends of the upper and lower support portions and adapted to produce repulsive magnetic fields each other. In order to make the machine operable with less effort, the first magnetic means (40) is arranged to generate by their magnetic fields, the repulsion force such that a weight of the upper support portion is offset, and the second magnetic device (50) is adapted, by their magnetic to generate the repulsive force so that the upper support portion to form a gap at a desired distance measure (D) is forced away from the lower support portion.
