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.
