Abstract: Strip edge relief is adjusted in a twenty-high cluster rolling mill by a set of double-tapered intermediate rolls in contact with the work roll. Rolling forces bend the work roll ends toward the tapered sections of the intermediate rolls to provide strip edge relief. Hydraulic actuators rotatably contact journals on the intermediate rolls and exert bending forces bending forces which bend the intermediate rolls so as to bending in the work rolls. This adjusts the strip edge relief.

Abstract: A new rolling mill configuration providing improved performance and lower cost than is possible for conventional four-high and six-high mills.This mill configuration contains eighteen rolls and may be described as an improved six-high arrangement, the improvement being in the provision of side support assemblies for the work rolls, thus enabling smaller work roll diameters to be adopted than is possible with four-high or six-high mills, resulting in lower separating forces and thus a lighter and less expensive mill construction for a given duty.

Abstract: A cluster type rolling mill intended to provide work roll sizes in the range between the small sizes available with current cluster mill designs and the large sizes available with current four-high mill designs is disclosed.This mill combines the advantages of existing cluster mills (heavier reductions per pass and between anneals) with the advantages of four-high mills (easier to maintain thermal equilibrium of work roll giving ability to roll at higher speeds).

Abstract: A rolling mill arrangement is disclosed in which a basically six-high mill has intermediate rolls which have no necks and are supported laterally by side support roller assemblies, and in which the work rolls are also laterally supported, whereby higher torque may be delivered to the mill to obtain heavier reductions without lateral flexure of the intermediate rolls.

Abstract: In a cluster mill having independently adjustable eccentrics on each saddle on at least one backing shaft to adjust the roll gap in line with each saddle, means to adjust the eccentrics in synchronism to produce a tapered roll gap and separate means to adjust the eccentrics in synchronism to produce a crowned roll gap, and, in combination, means to produce a roll gap with a composite crowned and tapered form.

Abstract: A planetary machining apparatus comprises a rotor and one or more drive spindle assemblies mounted thereon. Each drive spindle assembly includes a rotary spindle support mounted for rotation on the rotor about an axis parallel to and radially spaced from the rotor axis, a drive spindle eccentrically mounted on the spindle support for rotation about an axis radially spaced from the spindle support axis, and a machining element mounted on the drive spindle. A pair of bidirectional hydraulic motors are mounted on the rotor in operative engagement with the spindle supports for angularly adjusting the spindle supports to effect a radial displacement of the drive spindles and the machining elements relative to the axis of the rotor. A control arrangement including a rotary fluid distributor is provided for selectively operating the hydraulic motors during rotor rotation.
