  • Patent number: 8365566
    Abstract: A device for adjusting the distance of stripper chisels from a circumference of work rolls supported in chocks of a roll stand, wherein the stripper chisels are movable parallel to the rolling line in direction towards and away from the roll gap. To adapt to different operating positions and diameters of the work rolls, the stripper chisels are arranged in a horizontally displaceable stand roller table. The movement of the stand roller table is linked with the vertical movement of the bottom work roll so that the stripper chisel can be moved away from the work roll when the bottom work roll moves upward, and vice versa.
