Abstract: A method for producing a wire mesh mat that consists of intersecting longitudinal and transverse wires and to a mesh welding facility for welding a wire mesh mat from intersecting longitudinal and transverse wires, comprising a clocked supply device for a sheet of longitudinal wires in an X direction, a feed device for transverse wires that lie perpendicular to the longitudinal wires and to a welding portal for welding the wires at their intersections.

Abstract: A single-spot welding device having a welding ram, the welding ram having a welding electrode, wherein the welding ram is movable cyclically out of a starting position to a welding material, and an electric drive is provided, by means of which the welding ram can be moved to the welding material and by means of which the force can be applied to the welding material. The method for carrying out welding comprises the following steps: moving a welding ram of a single-spot welding device out of a starting position by means of an electric drive, pressing the welding ram during the welding by means of an electric drive, and moving the welding ram back into the starting position.

Abstract: The invention relates to a device for detecting flaws in a plastic woven fabric made of monoaxially drawn polymer ribbons, in particular polyolefin ribbons, preferably polypropylene ribbons, wherein in order to monitor irregularities, which are characteristic of flawed sections of the plastic woven fabric, an inspection camera is provided for taking images of the plastic woven fabric, and an analysis unit, which detects irregularities in the weaving pattern of the plastic woven fabric on the basis of the images taken by the inspection camera and which, when detecting irregularities in the weaving pattern indicating a flawed section of the plastic woven fabric, triggers an error signal, which actuates, for example, a flashing light or a horn, or which can be fed to a higher-level machine controller.
