Abstract: Method and apparatus for sectioning traveling elongate material. The apparatus has a pair of cutting cylinders mounted for rotation with their axes substantially parallel. Cutting edges are formed at the peripheries of adjacent tapered end faces of the cutting cylinders, the cutting edge of one cylinder being in close proximity to that of the other. The cutting cylinders are rotated in synchronism so that the cutting edges execute a cutting stroke in unison, the length of the cutting stroke being in excess of the width of the elongate material to be cut. A mechanism is provided which limits feeding of elongate material to material having a width less than the length of the cutting stroke. The method provides for the feeding of elongate material through a pair of rotating cutting cylinders which define a cutting path longer than the width of the elongate material.

Abstract: In a rolling mill for a metal workpiece and comprising a pair of rotary work rolls for reducing the thickness of the workpiece when it is fed therebetween, a carrier for at least one of the work rolls comprises a cam surface which can roll on a counterface provided on a backing member for the carrier. Means are provided for displacing the carrier, whereby the cam surface is rolled on the counterface of the backing member and the said one work roll is displaced to describe a path determined by the shapes of the cam surface and counterface. It is preferred that each work roll of the pair be supported by a separate displaceable carrier, each carrier having a cam surface which can roll on counterfaces of separate associated backing members.
