Abstract: The invention concerns a 4-high/6-high/18 HS cassette-type roll stand in which bending force is transmitted to bending journals (6) of roll inserts (7) by piston-cylinder units that are connected with Mae West blocks (3). Here, the piston at the piston rod (1) is fixedly connected with the Mae West block (3) and the cylinders (4) fit around the bending journals (6) at the inserts (7) of the rolls, so that thereby bending force can be transmitted directly to the bending journals (6) of the roll inserts (7).

Abstract: The invention relates to a cluster arm arrangement for the intermediate roll sets of 18 HS roll stands, wherein arranged between the chock at the operating side and the chock at the drive side are cluster arms which are pivotable laterally of the intermediate roll and in which the lateral backing rolls are integrated for support of the working rolls in the stand. In that case, arranged between the chock (1) and the cluster arm (2) is a pivot pin (3), which is fixedly connected with the cluster arm and about the axis of which the cluster arm (2) is pivotable, and a locking means for the cluster arm (2) as well as an abutment (6) with a restoring spring (6) are operatively arranged on the pivot pin (3) as a compact unit in the region between the cluster arm (2) and chock (1).

Abstract: The invention relates to a device for locking the chock (3) and the axial bearing housing (5) of a roll set as well as the roll change carriage (7) during rolling and during change of rolls. In that case provided at the roll housing (1) is a horizontally displaceable locking device (2) having locking elements (4, 6, 9) by way of which the locking device (2) for axial displacement of the roll is lockable to the roll chock (3) in order to fix the position of the axial bearing housing (5) with respect to the chock (3) of the roll or is lockable to the roll change carriage in the roll change position.
