<p>Tensile rolls (6, 8) are driven against the press rolls (4) and/or cutting blades (5), or driven tensile and knife rolls (7) extend over the entire width of the sheet to be folded. The press rolls and/or cutting blades can be axially adjusted simultaneously or one after the other using one or more threaded spindles (14). During axial adjustment, some of the press rolls and/or blades remain still, some are moved a first axial distance and/or some are moved a second axial distance.</p> |
