PROBLEM TO BE SOLVED: To make it possible to stably supply an accurate header by movably providing a slide bed for the header in the direction perpendicular to the moving direction of a head side first slide bed. SOLUTION: Two rails 402 are provided on the upper surface of a header fixing bed 40 in the direction parallel to a head side second slide bed H2, i.e., perpendicular to the moving direction of a head side first side bed H1, and a header slide bed 50 can bee movably mounted along the rails 402. Dovetail grooves 501 are provided over substantially the entire length in the longitudinal direction of the bed 50, and can be disposed at the position opposed to a fusion bonded article grasped by a tail side clamp at an arbitrary site from substantially the end to the end of a header tube P3 mounted on the bed 50. |
