Abstract: A metal strip and a process for manufacturing such a metal strip are disclosed. In order to be able to reproducibly manufacture a durable metal strip, it is proposed for a butt seam to extend essentially between a first cladding layer of a first strip transverse portion and a second strip transverse portion.

Abstract: A blade for a reciprocating saw, said blade being made from at least a bimetallic sheet material and comprising a flat body portion comprising a low-alloy steel material or a carbon steel material, a cutting edge portion comprising a high-speed steel material provided with a plurality of teeth arranged at a first edge of said flat body portion, and a back edge portion arranged at a second edge of said flat body portion opposite of said cutting edge portion, wherein said back edge portion is provided with a non-cutting micro-structured surface.

Abstract: A method for producing a primary material for a cutting tool, for example a primary material for a saw blade or a saw band, in which a band-shaped carrier of a metal carrier material and a wire of high-speed steel are continuously brought together along a lateral edge of the band-shaped carrier and transported into a welding device and the band-shaped carrier is welded to the wire along the lateral edge of the carrier to produce a bimetal band. The band-shaped carrier and the edge wire are welded to one another by at least a first welding device, which is arranged on one side of the band-shaped carrier, and at least a second welding device, which is arranged on the opposite side of the band-shaped carrier.

Abstract: Method and strip steel knife from a steel strip having a bainite and decarburized surface. The steel strip has a generally rectangular cross-section, and the method includes machining a plurality of beveled surfaces in a region of a longitudinal edge of the steel strip to create at least a cutting surface defining a longitudinal cutting edge; first hardening at least a part of the cutting surface to form a first cutting edge region of the longitudinal cutting edge; smoothing the cutting surface of at least the first cutting edge region toward the longitudinal cutting edge; and at least one further hardening in the first cutting edge region to form a distal cutting edge region of the longitudinal cutting edge within the first cutting edge region having an increased material hardness with respect to the first cutting edge region located outside the distal cutting edge region.

Abstract: A method for producing a preliminary material for a cutting tool and such a preliminary member, for example a preliminary material for a saw blade, a saw band, a cutting line, a punching knife, or a blade, wherein at least one first particulate cutting-edge material is applied to a planar carrier, the first particulate cutting-edge material is welded to the planar carrier, and the planar carrier is separated substantially along the weld joint thus produced.

Abstract: A method for producing a primary material for a machining tool and such a primary material, for example a primary material for a saw blade, a saw band, a cutting line, a punching knife or a blade, wherein a first flat carrier is arranged with one edge thereof along an edge of a second flat carrier, wherein the first and second carriers are welded together along the edges by supplying at least a first particulate cutting edge material, and the first and second carriers are separated again substantially along the welded joint formed as noted above.

Abstract: Cutting tool for flat materials. The cutting tools includes a band-shaped base body which has on one longitudinal side a working region with cutting teeth and on an other longitudinal side a supporting region with a supporting surface. The cutting teeth are formed with tips and include cutting sides emanating from the tips at an angle a to one another. In a longitudinal direction of the working region, the tips of adjacent cutting teeth have different distances to the supporting surface.

Abstract: The invention relates to a method and to an apparatus for producing a steel strip, in particular a steel strip having a bainitic microstructure, such as for example a spring steel strip or a punching tool, wherein the steel strip is made to pass continuously through the following treatment steps: austenitization of the steel strip at a first temperature above the austenitization temperature; quenching of the steel strip, by means of a gaseous quenchant, to a lower, second temperature selected in accordance with a desired steel microstructure. According to the invention, the gaseous quenchant is conducted onto the steel strip in such a manner that uniform cooling is achieved over the width of the steel strip.

Abstract: The invention relates to a tool for producing folding lines in flat materials which is composed of a metallic band-shaped base body with a working section and a supporting section with a supporting edge. To create a tool which forms grooved regions and scored regions between the grooved regions, in which scored regions the tool possibly only penetrates the flat material at isolated points, it is provided according to the invention that the working section is composed of grooving regions with a profile that is rounded in cross-section and of scoring regions with flank surfaces forming in cross-section from blades that start from a tip and extend to a base and are sharp-edged on both sides, wherein the outermost rounded profile surface of the grooving regions and the tips of the scoring regions have the same distance from the opposing supporting edge of the tool.
