Abstract
PURPOSE: To prevent the coil break of titled web material at the neighborhood of the weld point, by arranging the center line of the support roll for the web material, so as to shift a specified distance to the upstream side in respect of traveling direction of the material from the weld center line connecting centers of a couple of pressure welding rolls.
CONSTITUTION: The web material 30 and the flange material 40 are supplied in the direction of the arrow 5, and the flange material 40 is pressure welded to the web material 30 by a couple of pressure welding rolls 10 which are arranged so as to leave a vertical clearance between them; hereby the H-beam is formed and is sent out in the direction of the arrow 6. Hereupon, for the purpose of preventing the coil break of the web material 30, a couple of support rolls 20, arranged so as to leave a vertical clearance between then, are employed; besides, in this method, the center line of the rolls 20 is a distance l5 shifted to the upstream side in traveling direction of the material, from the weld center line 11. When the horizontal length of pressure welding fot the web material 30 by the rolls 20 is taken as L, lS = 0.2LW0.8L must be statisfied; hereby, the coil break of the web material 30 can be prevented.
