Abstract
Sheet material is physically contacted only at its lateral edge portions by transport elements for transporting the sheet material along a predetermined transport path. The central portions of the sheet material are not physically contacted, to prevent damage to them. Because the sheet material is held only at its lateral edge portions, sagging or bulging of the central portion of the sheet material could occur. To prevent this, the sheet material is tensioned in direction transverse to the sheet material transport direction, during actual transport, to an extent sufficient to prevent sagging or bulging of the sheet material during such transport.
