ABSTRACT:
Cross welds in metal tube moving continuously along a path are removed by means of a method which includes the sequential steps of generating signals representative of predetermined linear movements of the tube, detecting the presence of cross welds in the tube and, on detecting the presence of such cross welds, passing signals to a counter device which is operable after receiving a predetermined number of these signals to actuate a cutting device which removes the cross weld from the tube.
