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 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: 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.
