Abstract: The invention relates to a manufacturing method and a dispensing machine comprising a metering step and particularly a calibration of mass flow of each component, which is completely automatically implemented. Therefore, said dispensing machine of the invention guarantees a reliable calibration, free of operational or input error and is saving operator time.

Abstract: Safety confinement equipment for laser radiation includes a safety confinement enclosure having two laterally opposite openings through which at least one metal strip can pass, the enclosure including first and second jaw devices for clamping the strip disposed on a path of travel of the strip between the two openings, the jaws being transversely disposed at least over the width of the strip. A cutting or welding equipment head emits a beam of laser radiation to be confined, in which the beam can be moved transversely between a pair of jaws disposed opposite each other on one side of a surface of the strip. In the position in which the jaws clamp the strip, the engagement of the jaws on the surfaces of the strip induces the formation of a physical screen against the laser radiation, which prevents the radiation from passing through the two openings of the chamber.

Abstract: A joining machine for joining ends of successive strips in a strip treatment installation includes a device welding a first end of a strip to a second end of another strip, a first pair of symmetrical clamping jaws including a first upper and a first lower clamping jaw gripping the first end of a strip, a second pair of symmetrical clamping jaws including a second upper and a second lower clamping jaw gripping the second end of a strip, the clamping jaws holding and positioning the first end facing the second end for welding the ends together. At least two clamping jaws of the two pairs each include a part for contacting one of the ends to be welded to another end. The part has a geometry and at least one constituent material reducing a strength of eddy currents likely to be created in the clamping jaw by electromagnetic induction.

Abstract: A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position that is vertically below a reference wheel. The reference wheel is lowered vertically to come into contact and bear on the rotary roller. A distance between an index on a measuring arm of the frame and an articulated column is repeatedly measured during the continuous lowering movement of the roller. The distance is compared with a distance threshold for each of the repeated measurements until the wheel reaches a first operating position where the distance equals a predefined distance threshold factor. The first operating position is recorded as a reference point in a system for the vertical movement of the reference wheel.

Abstract: A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position. The measuring position is vertically below a reference wheel. The reference wheel is continuously vertically lowered so that its lower surface comes into contact with the rotary roller and produces a bearing force on the roller. The roller is continuously moved in the direction of lowering. A distance between an index, which is secured to a measuring arm of the frame, and an articulated column of the frame is repeatedly measured during the continuous movement. The distance is compared with a distance threshold for each of the repeated measurements until the wheel reaches a first operating position in which the distance is equal to a predefined factor of the distance threshold.
