  • Patent number: 9770745
    Abstract: The invention relates to a roller device (50) having a stand and two roller sets having at least two rollers (52, 53, 54, 55) disposed in a stand (51) of the roller device, wherein a roll material (56) can be fed between two rollers (53, 54) of the two roller sets for rolling, wherein at least the rollers (52, 53) of a roller set can be displaced in the rolling direction relative to the stand (51), wherein adjustment means are provided between a roller bearing for receiving the rollers and the stand, each on both sides of the roller bearing. It is thereby particularly advantageous if the circumferential speeds of the rollers, such as the working rollers, are different.

  • 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.
