In radial The tie rods are in the direction of the roller 10 by means of at least one spacer 38 are held in position. When using at least two spacers can be arranged according to the respective load case are.
- the base body 14 is again from surrounded a particularly flexible tube 30.

- Base body 14 can, for example, have a flexible layer accordingly varying radial layer thickness or for example discrete elastic elements be applied with appropriate varying thickness. Even with the same Stiffness of the relevant layer or the relevant Elements thus have a higher flexibility towards the roller ends or less rigidity of the surface in contact with the web.
- FIG. 5 shows another in a schematic, partially sectioned illustration Embodiment of a roller 10 with successive zones in the axial direction different stiffness, for example by corresponding sections 18 'of a flexible layer or by correspondingly different flexible elements 20 can be formed.

- one over the length of the surface in contact with the web has a constant rigidity (modulus of elasticity) flexible Be applied layer in the thickness from the center to the edge in Ratio of the global deflection of the base body increases.
- the edge region of the, for example, formed by a metal tube Base body be conical or parabolic.
- one over the length of the surface in contact with the web has a flexible layer which is constant in thickness be, whose rigidity from the center of the roller to the edge in relation to the global deflection of the drum drops.
- the base body can be cylindrical be executed.
- the implementation of the first variant is in particular by a rubber elastic Layer possible, which is applied in the peripheral zones within a rubber cover becomes.
- the material properties of this layer are then preferred determined by the requirement of a horizontal surface line that is as horizontal as possible.
- the implementation of the second variant would be carried out as a material layer require a variable modulus of elasticity across the web width.
- An easier one The possibility to be realized is, for example, discrete elastic To use elements or spring elements, for example, by Change the distance between these elements and / or by a different one Element stiffness the required variability of the bed stiffness enable.
- an outer tube can be pulled on (wall thickness for example 5 - 10 mm for a version made of metal, for example).
- Such one outer tube would have to be taken into account when dimensioning the spring elements.
- the spring elements can for example formed by rubber-elastic, ring-shaped bodies or, for example, as metal spring packages wound all round. There is also a preload of these elements conceivable.
- the material parameters can at least essentially can be determined or determined as follows, for example:
- the flexible layer can in particular be modeled as a homogeneous layer (edge thickness, for example 20 mm, thickness towards the center of the drum, for example, about 5 mm, length, for example, about 3000 mm) with an elastic modulus of about 1 N / mm 2 .
- This size represents a lower limit for the elasticities of polymeric materials (modulus of elasticity between 1 and 500 N / mm 2 ).
- a rubber cover can serve as a protective layer against the flexible layer.
- the result is that in this case, despite a significantly higher total deflection of the base body, the difference in the deflection of the surface in contact with the web (rubber covering) between the edge and the center has decreased significantly.
- the greater total deflection of the base body results, on the one hand, from the reduction in wall thickness of the inner body formed, for example, by a metal tube in the edge zones (conical course from, for example, 40 to, for example, 20 mm), and on the other hand from the uniformity of the paper pressure on the surface in contact with the web (see figure 7).
- FIG. 7 only the abrupt end of the flexible layer leads to a pressure peak at this point. This transition should be optimized.

Man erkennt auch, dass das Material mit 1 N/mm2 bei den angenommenen Schichtdicken geringfügig zu steif ist. Dies wäre durch eine weitere Erhöhung der Schichtdicke in den Randbereichen beziehungsweise durch einen noch geringeren E-Modul des Materials auszugleichen.

- geringe Walk-/Deformationsarbeit, trotz großer Deformation bei jeder Umdrehung;
- Temperaturbeständigkeit bis zu jener Temperatur, die durch die Deformationsarbeit entsteht;
- kostengünstige Herstellung und einfache Aufbringung auf das Rohr.
