PURPOSE: To prevent a lowering of high productivity of an automatic welder and a conveyor equipment by means of the press-marking by sending a sheet panel along a conveying path and press-marking the same without interrupting the sending.
CONSTITUTION: A disk 12 having protrusions and a disk 12' having grooves are rotated. The sheet panel 4 is press-marked while the sheet panel 4 is bitten between the disks 12, 12'. As the press-marking is executed during conveying motion, it is unnecessary to stop the sheet panel 4 and to accelerate the same again. Therein, male and female parts of the press-marking tool also can take linear reciprocal motion while synchronizing the displacement of the sheet panel 4, in place of the rotational motion. As the press-marking tool is jointed to the welder and is assembled with oiling and brushing stations, conveying expenses of the sheet panel 4 are preferably cut down.
