| 摘要 | A separation device is usable for separating portions of a material web. The separation device has at least one front clamping device, with at least one front clamping point, and at least one rear clamping device, with at least one rear clamping point, and at least one first stretching element. The separation device can be switched between at least one traversing mode and at least one separation mode by the movement of at least the at least one first stretching device between at least one first traversing position and at least one first separation position. A transport line is the shortest connection between the at least one front clamping point and the at least one rear clamping point, that connection line completely on a vertical reference plane and traversing or running at a tangent to any component of the separation device on the respective same side as one of a transport path provided for the material web and the portions to be separated. The transport line, in the at least one separation mode, is 2 mm longer than in the at least one traversing mode and has the smallest radius of curvature in the at least one separation mode of at least 0.05 mm. A first reference plane and a second reference plane are mutually spaced apart in an axial direction and a first transport line, lying on the first reference plane, and a second transport line, lying on the second reference plane, have different lengths when the first stretching element is located in the at least one first separation position. | ||||||
