PURPOSE:To enable continuous welding of material more than 0.1mm. thick by connecting a driving horn squarely to the center of one surface of a rotating disc-shaped tool horn to arrange a disc-shaped pedestal rotating at the same circumferential velocity as the horn at the loop position point of the deflecting vibration thereof. CONSTITUTION:When integrating a disc 11 and a driving horn 3, a tool horn 4 rotates on the axis line of the driving horn 3 and apply longitudinal vibration to the driving horn, a circular deflecting vibration is generated in the disc 11. When a disc-shaped pedestal 12 turning at the same circumferential velocity as the tool horn is arranged as opposed thereto at the loop position point 14 of the vibration 13, the deflecting vibration can be utilized most efficiently. In addition, the width of the pedestal 12 can be 70-80% of the amplitude thereof and the proper selection of the diameter and thickness of the disc 11 and the service frequency enable the generation of a deflecting vibration of 2-8 order mode. Thus, a plurality of weldin lines can be formed continuously on a plastic sheet at a desired interval. |
