PURPOSE:To stably enable on-line production at high velocity to joining and coiling by approaching a flat foil and a waving foil to form V shaped grooves, irradiating laser beam from the opening parts thereof to weld contacting parts between the flat foil and the waving foil and forming a honeycomb shape. CONSTITUTION:The first foil 1 and the waving foil 2 are approached with guide rolls 3 and forming gears 4, and a metal-made squeeze roll 5 and a metal- made squeeze gear 6, and the laser beam 7 is condensed with a condenser lens 8 at this V groove to irradiate the condensed beam 9. By this method, the contacting part between the flat foil 1 and the waving foil 2, is welded to manufacture a honeycomb hoop 10. The joining velocity (v) for the honeycomb hoop 10 is decided with a driving roll 11 and a driving gear 12. The forming gears 4 are one forming the flat foil into the waving foil. The guide roll and the guide gear are freely rotated and force is applied so that the flat foil and the waving foil always contact to hold the V groove shape. By this method, the honeycomb hoop having excellent durability providing sufficient joining strength, can be obtd. |
