摘要： The method is used to make metal fibers, more particularly steel fibers, from strip-shaped flat material, where the metal fibers have a substantially rectangular cross-section, and at least one of the wide side faces, preferably both of the wide side faces, is provided with at least one V-shaped anchor groove running longitudinally of the fiber. First, a material matched to the strength required for the metal fibers when they are used later on is used as the metal strip. In a first production line the metal strip, is fed from a coil to a straightening and transporting unit (3) by a driven and controlled unwinder (1). Downstream of a crop shear (4) that forms the leading end of the strip, the metal strip is fed to a profiling roll pair (6) consisting of an upper roll and a lower roll and forming a rolling tool. The profiling roll pair introduces anchor grooves and fracture grooves. Subsequently, the metal strip passes through a combined scoring and straightener (7) for scoring or straightening the anchor lines in the fracture grooves by means of one or more scoring roller pairs, and the metal strip is finally wound as a coil again by a winder (8). Thereafter, the last process step of the fiber make is carried out at a longitudinal and transverse dividing unit.

摘要： The method serves for expanding and formatting profiled metal strip material (1) to form a netting-like mat structure (2) of a predeterminable mesh width by a continuous drawing-open process. For this purpose, the strip material (1) is provided with notches (3), which extend in the longitudinal direction of the strip, are of a limited length and between them form metal strands (11), wherein, after the expanding and formatting, the unnotched regions form netting nodes (4) and initially the metal strands (11) are connected to one another by way of adjoining webs in the base of the notch. The webs have fatigue-fracture induced incipient tears formed by flexural deformation. The remaining web is then severed by a separating roll, so that the metal strands (11) are reliably separated from one another in the notch region and the strip material (1) can be drawn open to form the netting-like structure. The strip material (1) is first drawn open at the beginning of the strip to the intended mesh width in such a way that some rows of mesh are aligned orthogonally and oriented at right angles to the edge of the strip with respect to their mesh diagonal. The prepared beginning of the strip is placed with the meshes onto the spikes (5) of a spiked roll (5.1) of a pair of rolls (5), after which the pressure roll (5.2) of the pair of rolls (5) is infed towards the spiked roll (5.1) and with it forms a rolling gap. In this case, the arrangement of the spikes (6) is chosen such that every second mesh—in both orthogonal directions—is shaped by a spike (6), in that the spikes (6) of the spiked roll (5.1) enter the clearances (7) in the pressure roll (5.2).

摘要： The profiled metal fibre with a substantially rectangular cross-section, also with bent fibre ends in the form of a clip, is used to stabilise, bond, attach or join materials and construction materials such as concrete, wood, paper and the like. The fibre edges of the fibre outer surfaces extending in the longitudinal direction of the fibre are designed as edge surfaces (2) oriented at an angle to the fibre outer surfaces in the manner of a bevel. The two wider fibre outer surfaces (3.1, 3.2) of the rectangular fibre are provided with V-shaped channels (4) extending in the longitudinal direction, wherein the edge surfaces (2) are provided with projections (6) and the V-shaped channels (4) are provided with end zones (5) that bound their longitudinal extent. The projections form anchoring heads and the end zones form anchor surfaces with respect to the material to be stabilised, bonded or attached.

摘要： The method serves for the production of a wire strip (1) comprising a plurality of wires (2) arranged parallel to each other. For this purpose a metal strip is first pre-notched either on one side or both sides for the formation of the wires (2), whereby wires (2) are generated which are still connected to webs (3). To transform the webs (3) subsequently into thin, easy to separate and, when separated, smooth and burr-free separation webs forming separation areas, the wire strip (1) is subjected to a milling process during which each web (3) is subjected to a multiple bending strain along the longitudinal axis thereof in such a way that incipient cracks form, due to fatigue fracture, in the area of the webs (3), and thereby the separation web is created.
