A telescopic drive spindle assembly for a rolling mill permits the assembly to accommodate axial displacement of the roll. The assembly has first and second overlapping members with a piston in one member being displaceable in a cylinder in the other member. The piston defines a chamber and a quantity of gas in the chamber serves to urge the piston in the direction out of the cylinder so as to increase the effective length of the drive spindle.

In an arrangement for coiling metal strip on a downcoiler, the strip is directed to the downcoiler by a pair of pinch rolls and one or both of the rolls are used to steer the strip to a desired position on the mandrel so that a coil with tidy vertical sides is formed on the mandrel. One roll of the pair of pinch rolls may be skewed with respect to the other roll or both rolls may be skewed to the direction of travel of the strip material.

A combination for accurately determining the position of the movable part of a piston-cylinder device relative to the fixed part includes a long stroke position transducer movable in the operating direction of the device; a structure movable with the piston-cylinder device and which has a part extending in the operating direction; two position transducers positioned side-by-side and their direction of movement is normal to the operating direction. The movable parts of the two position transducers bear against the part of the structure. If there is no tilting of the piston within the cylinder, then electrical signals from the two position transducers remain unchanged, but the signals are changed if the piston tilts within the cylinder.
