Device for measuring and controlling the gap between rollers in a roller stand

In combination with a roller stand defining the axes of a pair of opposed rollers whose shafts are mounted therein, a device for measuring and controlling changes in the gap between said opposed rollers, said device comprising first and second partial bearings engaging the sides of the shafts of the rollers which face each other, first and second measuring bridge parts, first and second measuring elements mounted on said bridge parts and connected to the respective partial bearings, preloaded spring means arranged between said first and second elements for biasing said partial bearing away from each other whereby said partial bearings and the respective said elements connected thereto will move relatively in conformity with relative movement of the rollers, and guide means guiding said bearing portions for relative movement in a direction parallel to a vertical plane of the axes of the rollers.
