PURPOSE:To enable a continuous welding satisfactorily by a method wherein a driving horn is connected squarely to the center of a disc-shaped tool horn to turn it with the horn as the rotating shaft and a disc-shaped pedestal turning at the same circumferential speed as it is arranged so that the cylindrical surface of the tool horn and that thereof comes closer to each other. CONSTITUTION:A disc-shaped tool horn 11 has a driving horn 3 connected squarly to the center thereof integrally and rotates on the axis line thereof. A disc- shaped pedestral 12 rotating at the same circumferential velocity as the tool horn is arranged as opposed to the tool horn 11 so that each other's circumferential surfaces comes closer and when the driving horn vibrates longitudinally sandwiching plastic films 10, the tool horn 11 generates a circular deflecting vibration to fuse the films 10 together. Thus, a thick sheet more than 0.1mm. thick, for instance, previously impossible to fuse, can be fused continuously and at a high speed. |
