Abstract: Sensors of the longitudinal edges and/or the width of hot roll metal strip are located immediately ahead of the trimming blades and are used to transversely adjust the trimming heads and/or the centerline position for the strip so that in subsequent trimming operations, the trim widths are identical at both sides. The cutting heads can be positioned in indentations at junctions between the successive segments of the strip.

Abstract: A method of measuring planarity of strip in a strip-rolling line or a strip-processing line in which a measuring beam, a plurality of measuring beams or discrete measuring pins in an inclined pattern across a measuring roller, measures the tension forces acting upon the strip to form a force summation foundation across the strip width. A tension distribution function is derived from the force summation function by taking derivatives of the force-summation function with respect to the width dimension of the strip and, if desired, dividing that derivative by the thickness of the strip.

Abstract: A strip treatment line in which downstream of the processing roll stand for stainless steel strip, first and second tension rolls are provided to directly form a prestretching zone A for elastic or elastoplastic stretching of the strip following the dressing mill stand and for providing an afterstretching zone with elastoplastic or plastic stretching of the strip.

Abstract: A stretch leveling apparatus having at least two stretching zones and wherein the lengths of the first and second stretching zones are each at least 0.5 times the maximum strip width.

Abstract: A trimming apparatus for metal strip has trimming heads on opposite sides of a turntable along each edge of the strip so that the trimming heads can be rotated into the trimming position or into the maintenance and blade-replacement positions. On each of the turntables as well a scrap-strip cutter is associated with the respective trimming head and the scrap-strip cutters are disposed diagonally opposite one another across the turntable and each trimming head and its scrap-strip cutter on one side of the turntable is connected to a clutch half on the opposite side of that turntable so that the scrap-strip cutter and the trimmer are driven by a common drive.

Abstract: Crossbow in metal strip in a strip processing line is eliminated immediately upstream of a strip processing device by measuring the crossbow and controlling response to the measured value penetration depth of a correcting roller into strip while the latter is supported by a pair of support rolls. The device is provided immediately upstream of the processing unit.

Abstract: A method and apparatus for the contactless determination of planarity and a ferromagnetic metal strip during transit of the strip through a strip-processing line or cold-rolling line. Hysteresis loops repetitively impressed in the metal strip and the tangential magnetic field strength is measured at a surface thereof and electromagnetic parameters are determined from the time course of the tangential field strength signal. The parameters are functions of the mechanical stress which is evaluated to determine residual intrinsic stress distribution and then the planarity or nonplanarity of the strip.

Abstract: An apparatus for removing binder straps from coils of metal strip in which a cage is engageable with the coil and has a blade carriage displaceable over at least a region in which binder straps may be provided in a continuous manner so that a wedge can engage beneath the straps in succession and a cutting tool can cut through straps in a single continuous operation without interrupting the movement of the carriage. The wedge and the carriage can be provided with clamping elements to engage the strap after it is cut to allow it to be transported to a scrap bin.

Abstract: Strip tension in metal strip subjected to a plastic deformation such as skin or dressing rolling, stretch bend leveling or stretching is adjusted by local variation of the temperature to establish a temperature profile which minimizes waviness and camber in metal strip.

Abstract: Rolls of a strip line are cleaned by directing jets of a cleaning liquid thereagainst from nozzles which are mounted so that their distances from the roll to be cleaned can be set or controlled.

Abstract: The planarity of a strip, especially metal strip is measured in a measurement zone in which the tension of the strip has been reduced in a targeted way by braking the strip. The braking force should be practically equal to the strip tension.

Abstract: A method of descaling rolled or cast metal strip, especially stainless steel or titanium-alloy steel strip in which the initial descaling is effected in a stretch-bend leveler and the annealing furnace directly follows the stretch-bend leveler and is directly followed by a pickling station so that any shot blast or brush descaler upstream of the annealing furnace is not required.

Abstract: A strip line or line for processing nonferrous metal sheets and plates has linear motor stators provided for contactless adjustment of the tension or stress distribution in response to planarity and profile measurements.
