Abstract

PURPOSE: To make the life of welding electrodes considerably long and make working efficiency higher by forming one of the circular blades on the upper right and left sides of a seam welding machine of double cut rotary shear built-in type into an outer blade with respect to the lower circular blade.
CONSTITUTION: Upper right and left circular blades 3a, 3b are supported to a revolving shaft 5 by making the opposing spacing lu thereof equal to the opposing spacing ld of lower right and left circular blades 4a, 4b. These are disposed by deviating the center Ou between the right and left of the spacing lu by the approximate blade width w of the circular blades 4a, 4b from the center Od between the right and left of the spacing ld. Since in this way the circular blade 3a becomes an outer blade with respect to the circular blade 4a and the circular blade 3b a circular blade with respect to the circular blade 4b, the burrs P at the cut end faces of succeeding and preceding strips 2, 1 are formed on the upper and lower sides respectively. Hence, during welding, the burrs P face the other strip side and will not penetrate in the lower electrode 10b. In addition, a scrap 1a engages with the peripheral surface of the circular blade 4a and does not drop deep into between the circular blades 4a and 4b, thus working efficiency may be improved.
