A system for cutting to length at least two strands of long rolled products (3, 5) preferably coming from a hot rolling mill. The system includes shears comprising at least two rotatable drums (4,6), each drum having a cutter (8,8′,10,10′) arranged to cut simultaneously at least two strands of long rolled products into finished segments. The system further includes at least two movable guides (12,14), each including at least two channels, each guide arranged to receive and guide at least one strand (3,5) of long product. The guides are movable between a position wherein, in operation, the strands of long product are located in positions either outside of the trajectory of the cutters in a position wherein the strands cannot be cut or wherein the strands are located on the trajectories of the cutters and can be cut by the cutters.

A pinch roll delivers a respective rolled product. A control device opens the pinch roll at a respective trigger time and at a respective transport speed of the respective rolled product. The control device determines the respective trigger time and/or the respective transport speed using a model that depends on a coefficient of friction. After opening the pinch roll, a measuring device detects iteratively a position or a derivation in time of the position of the respective rolled product. The detected positions or the detected derivations in time of the position are provided to the control device. The control device in dependency on the positions or the derivations in time of the position updates the coefficient of friction and uses the updated coefficient of friction for determining the respective trigger time and/or the respective transport speed for the next rolled product delivered by the pinch roll.

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.

An apparatus for applying pressure to at least a portion of an edge surface, which bridges opposing faces of a workpiece, comprises a frame, a first roller, a second roller, a rotation-control member, a first biasing member, and a second biasing member. The first roller and the second roller are coupled to the frame, rotatable relative to the frame about a first pivot axis, and translationally fixed relative to the frame. The rotation-control member is movable relative to the frame, controlling rotation of the first roller and the second roller relative to the frame. The first biasing member is coupled to the frame and is configured to operate in tension. The second biasing member is positioned, in compression, between the frame and the rotation-control member.
