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.
Claims8
A roll stand for flat rolling a workpiece moving in a predetermined direction, the stand comprising:
- a frame;
- an upper backing roll and an upper working roll forming an upper roll set in the frame and rotatable about respective vertically spaced and parallel upper axes transverse to the direction;
- a lower working roll and a lower backing roll below the upper set and forming a lower roll set in the frame below the upper set and rotatable about respective vertically spaced and parallel lower axes transverse to the direction, the working rolls defining a gap through which the workpiece passes in the direction, the working rolls being of smaller diameter than the respective backing rolls, the upper and lower working rolls being of the same diameter, the upper and lower axes all being parallel;
- a mount shiftable in the direction on the frame and on which both of the rolls of one of the sets are pivotally mounted;
- and
- respective pairs of vertically spaced adjusters braced between the frame and the mount upstream and downstream in the direction and generally level with the axes of the respective rolls of the one set for shifting both of the rolls of the one set in the direction relative to the frame through a horizontal offset between the working rolls of between 50 mm and 120 mm.
