Title:
METHOD AND DEVICE FOR CUTTING AND WELDING STEEL BELTS
Document Type and Number:
WIPO Patent Application WO/1987/005244
Kind Code:
A1
Abstract:
A method for cutting and welding steel belts and an apparatus thereof, wherein both of the preceding and succeeding steel belts fed continuously are cut at the ends thereof facing each other, said steel belts being butt-welded with sections thereof formed by said cutting as surfaces to be joined. In said cutting and welding, cutting and joining for welding are carried out in such a condition that one of side edges at the end of the steel belts is set so as to be parallel to the center line of a continuous processing line wherein said cutting and welding are carried out as described above, and further, in setting said side edge, the preceding or succeeding steel belt is attracted by means of an electromagnetic chuck within a work table of the continuous processing line, causing the preceding or succeeding steel belt to be drawn toward the side of a reference block disposed in parallel to said center line, so that one of the side edges of the preceding or succeeding steel belt is abutted on the reference block. In bringing said sections into face-to-face contact prior to welding, the preceding steel belt is attracted and held by the electromagnetic chuck on the work table with one of side edges being set in such a manner as stated above, while a part of the end of the succeeding steel belt is lifted so as to have a loop-like shape, causing the section thereof formed by cutting to be inclined downward with respect to the section of the preceding steel belt so that both ends come into contact with each other.
