The invention relates to a device for continuous treatment of a metal strip (), in particular a metal strip consisting of aluminum or an aluminum alloy, or consisting of a non-ferrous metal or a non-ferrous metal alloy, said device comprising at least one temperature control device () through which the metal strip () is guided in a floating manner, and comprising at least one strip position regulation unit (), by means of which the position of the metal strip () can be controlled or regulated on the belt movement plane (E) and transversely to the strip running direction (B), wherein the temperature control device () has at least one entry-side heating section () and an exit-side cooling section (). The invention is characterised in that the strip position regulation unit () that works in a contactless manner has at least one contactless strip position detection element () and at least one linear motor () and is arranged within the heating section () or between the heating section () and the cooling section ().

Method and apparatus for continuous treatment of a metal strip

A method of splicing a trailing end of a downstream metal strip to the leading end of an upstream metal strip. The method has the steps of overlapping the leading end of the upstream strip with the trailing end of the downstream strip, and thereafter friction welding the overlapping ends together at a plurality of spots at which respective spot welds are thereby formed.

Method of and apparatus for splicing metal strips

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.

Method of trimming strip, especially hot roll metal strip

A strip coating device for coating of strips, particularly metal strips, has at least one application head for applying coating substances to the strip. The application head has at least one application roller that applies the coating substance to the strip, and having at least one supporting roller disposed on the side of the strip opposite the application head. The application head works on the strip either in a first functional position where the strip is supported by the supporting roller, or, in a second functional position outside of the supporting region of the supporting roller.

Strip coating device

In combination with a cutting apparatus having a pair of blades with edges that are closely juxtaposed relative to an axis with each other and where at least one of the blades is movable along the axis to set between axially confronting faces of the blades at the edges a predetermined gap, a system for measuring the gap has a stationary support, and respective means associated with each of the blades for measuring a distance between the support and the face of the respective blade.

Gapping system for dual-blade trimmer

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.

Method of and apparatus for contactless planarity measurements on ferromagnetic metal strip

A method and process line for producing cold-rolled stainless-steel or titanium-alloy strip from hot-rolled strip descales the hot-rolled strip by shot-blasting and/or brush-polishing and then cold-rolls the descaled strip. The cold-rolled strip, at its final thickness, is annealed and then pickled, all in a single continuous line.

Method of and process for cold-rolling of stainless-steel and

The method and apparatus provide for transversely separating and laterally trimming or finishing continuously passing strips in processing lines for strip material, such as metallic strip. The strip is first severed in transverse direction and immediately thereafter is trimmed at the sides thereof. The time required for adjusting the lateral shears is approximately equal to that of the coil exchange operation leading to the time gained, and stoppages of strip in the operating stages are precluded.
