Abstract
PURPOSE: To form materials into the specified butt shapes and make possible good welding by cutting the material edge parts by the cutting tool-shape protruding part provided on the material insertion side of a seam guide plate mounted to the electric welded tube producing device.
CONSTITUTION: A cutting tool-shape protruding part 7 is provided on the material insertion side of a seam guide plate 6, and the edge part of a hoop material 1 in contact with this plate 6 is trimmed to the edge shape suited for welding. Roll-form pipe-circumference-pressing devices 8 are provided in both side positions of the material 1 under forming opposing to the protruding part 7 and the amount of cutting of the edge part of the material is adjusted by adjusting this pressure. Since this edge trimmer device trims the material edge parts just before the welding point upon completion of forming, the arbitrary butt shape may be obtained.
