摘要： A shearing apparatus for performing several modes of operation on travelling or stationary material. Two cooperative knife drums, which can be rendered rotatable or non-rotatable, form a gap whose spacing is varied by hydraulic piston cylinder assemblies, one mounted on opposed ends of the upper or bottom drum. The adjustable knife drum is held in a parallel or non-parallel positioning or caused to rock with or without additional high frequency oscillations by controlling and regulating the pressure in the cylinders, while simultaneously moving the upper drum towards the lower drum and/or rotating both drums.

摘要： A back up roll assembly for supporting an intermediate roll and an upper work roll consists of a plurality of rotatable rollers spaced apart on a common shaft by fixed saddles and in engagement with the intermediate roll. The number of saddles exceeds one more than the number of rollers so that the back up roll assembly begins and ends with a saddle, each saddle being engaged by a piston cylinder assembly mounted in a frame, which frame takes up all of the rolling load and adds rigidity to the compensating system. Each piston cylinder assembly controls the positioning of its saddle and its neighboring rollers to exert a localized influencing effect onto the intermediate roll to compensate for, and/or control roll deflection.

摘要： A hot or cold leveler is provided having conventional high loaded driven work rolls backed up longitudinally across their face by a plurality of short backing rolls. A series of lower work and backing rolls are cassette mounted on the lower main frame of the leveler. The upper backing rolls are mounted on an intermediate support frame designed for limited flexure and which in turn is supported across its length by a plurality of hydraulic piston-cylinder assemblies fixed in the top main frame of the leveler for contouring of the leveling action. Each cylinder is controlled by a servo valve which can be operator-adjusted to work the sheet material across its width dependent on sheet flatness. Buckling at the center, quarter, or edges of the sheet can be removed by a corrective positioning of the piston-cylinder in the location of the buckle. Entry and delivery rollers are similarly servo-controlled. The entry roll is backed off to permit the sheet product to enter the machine and it acts as an anvil roll. The delivery roll is adjusted to deliver flat product onto a delivery table. Pressure transducer means and piston position transducer means are provided in each cylinder, whereby a positive feedback signal is provided due to loads on the flexible beam exerted by the material being worked to withdraw or inject hydraulic fluid to the cylinders.

摘要： A sizing press has a pair of opposed rotatably supported pressing tools for reducing the width of a flat metal slab. Piston cylinder assemblies rotatably oscillate the pressing tools relative to each other. Each pressing tool has first and second slab-contacting surfaces which extend in different planes. The invented method of this invention includes the steps of moving the pressing tools toward each other against the sides of a metal workpiece and reducing the width of an initial workpiece length. Thereafter, rotating the pressing tools to further reduce the width of only a portion of the initial workpiece length and to reduce the width of an adjacent workpiece length.

摘要： The distribution of tension in flat products is measured by a bendable roll engaged by segmented rolls. The bendable roll has a peripheral surface which engages the width of workpiece and is elastically bendable along its axis under the tension in the workpiece. The elastic deformation of the solid roll exerts loads on the segmented rolls and one or more sensors detect the transmitted loads.

摘要： An arrangement for winding material onto a coiler drum along a passline of a hot reversing mill comprising an apparatus having two pivotal arms mounted on a common shaft and movable in a different arcuate path toward and away from the coiler drum. Rollers at the end of the arms tightly enwrap the material around the drum when the arms are positioned against the drum as the material is being underwound onto the drum. The roller of one of the arms may act as a deflector roller when positioned away from the drum as the material is being overwound onto the drum. The other arm consists of two wrapper rollers on a pivotal mounting for their proper orientation around the drum and for flat passes of the material through the mill. This other arm is positioned away from the drum below the passline to allow a retractable table roll assembly consisting of a plurality of table rolls to be positioned in the passline for supporting the material.
