- the parameters which change during, for example, rolling, such as roller wear (smaller diameter), brush wear or a changed position of the rollers, have no influence on the amount of the setting force because their changes are automatically compensated by the construction according to the invention. This also applies to changing diameters or working positions when changing roles.
- the force transmission element between the adjusting element and pivot lever is designed as a compression spring. This is a structurally simple embodiment.
- Adjusting element is designed as a pivotable about the pivot axis mounted adjusting lever. Such a design allows a particularly simple
