International ClassB23K 037/047Foreign Application Priority Data1991-01-08 DEAbstractA strip welding machine for welding abutting cut surfaces at a strip beginning and at a strip end of metal strips. Cutting tools are provided for producing the cut surfaces. A welding apparatus is used for welding the cut surfaces. A cutting stop which can be raised above the plane of the strip is arranged in front of the cutting tool on the entry side and a measuring drive operating in strip travel direction is arranged in front of one of the strips. A cutting stop which can be raised above the plane of the strip is arranged following the cutting tool on the exit side also in strip travel direction and a measuring drive operating against the strip travel direction is arranged following the other of the strips. The measuring drives ensure that the respective strips are exactly positioned initially in cutting position and subsequently in welding position.Field of SearchStrip leading end to trailing end bonderWith means to treat workpieces (e.g., cutting, deforming, etc.) Work-responsive (e.g., temperature, orientation of work, etc.) Including means to orient work or position work portion relative to another work portion WITH SIGNAL, INDICATOR, GAUGE, OR STOP | |
