Abstract: In a multi-roll rolling stand having two intermediate rolls 3 to 6, which each have only one tapered roll barrel end, in each case two tapered roll barrel ends lie on each side of the rolling stand. The intermediate rolls 3, 4 and 5, 6, the two roll barrel ends of which lie on the same side of the rolling stand, are independently displaceable in an axial direction. Due to the axial offset of the tapered roll barrel ends which can be achieved in this manner, the support curve of the work rolls 1, 2 in the edge regions of the rolled strip can be finely adjusted. In addition, the support curve in the center region of the strip can also be adjusted if in each case one of the two work rolls 3, 4 associated with each work roll 1, 2 is contoured.

Abstract: A strip coiler has an expandable coiling drum having on one end an outward flange which fits against an outward end flange on the end of a rotative drive shaft. The interfaces of the flanges have radial interlocking grooves and ridges. To hold the flanges tightly together, a collar encircles the flanges and has inward flanges embracing the outward flanges of the drum and shaft. The drum's flange and the corresponding inward flange of the ring form a bayonet joint so that by partial relative rotation of the ring and drum the drum can be removed and replaced. The flange of the collar which engages the shaft's flange is provided with a fluid pressure means so that when the bayonet joint is in its locked condition, the drum and shaft flanges are forced tightly together when this means is provided with fluid pressure. Release of the fluid pressure permits relatively easy partial rotation to unlock the bayonet joint for removal or replacement of the drum and its flange with respect to the flange of the drive shaft.
