By attaching an elastic member made of a rubber-based elastic material to the material and providing a slit having a cross section substantially perpendicular to the processing surface on the opposite surface of the elastic member, it is possible to press down the workpiece material having a step when welding the material. Each elastic member attached to the metal fitting and divided by the slit is individually deformed along the shape of the stepped portion, so that the pressing force to the welded portion is uniform, and the work piece having the stepped portion is deformed individually. The object of the present invention is to provide an ultrasonic processing machine that can perform good welding on materials.

れることにより阻止される。 First, the presser foot lifting lever 23 is operated by the operator to raise the presser foot roller 15 as shown in FIG. 2, and the side edges are bent and overlapped as shown in FIG. After the workpiece material is placed on the processing surface 13, it is made up of two sheet materials P and Q, a film sheet material R that covers the stepped portion a, and a thermal adhesive film S inserted between them. When the presser foot lifting lever 23 is operated again, the presser foot roller 15 is lowered. After that, when a foot pedal (not shown) or the like is operated, the motor 8,
19 are rotated together, power is supplied to the ultrasonic vibrator 9 from a high frequency generator (not shown), and the processing horn 12 starts ultrasonic vibration. At this time, it is attached to the presser roller 15 and the slit 17
Each elastic material layer 17a, 17b, 17c of each elastic member 17 divided by d has a fourth layer due to the elastic action of the portion that comes into contact with the stepped portion a of the workpiece material.
As shown in the figure, it is recessed and deformed so as to come into close contact with the stepped portion a and the adjacent portions b and c of the material to be processed. Therefore, a substantially uniform pressing force is applied to the stepped portion a and its peripheral portions b and c of the workpiece material, and the frictional heat generated by the ultrasonic vibrator 9 is applied to each portion of the stepped portion a and its surrounding portions b and c. As the motors 8 and 19 rotate, the workpiece material placed on the processing surface 13 is continuously transferred, so that uniform welding is continuously performed in each part of the workpiece material. Ru. Furthermore, the elastic member 17 may be damaged due to abnormal expansion due to the expansion of the air bubbles in the elastic material layer 17a, especially the foamed nitrile rubber elastic material layer 17a, due to the frictional heat generated during this welding. This is prevented by the air in the bubbles leaking to the outside from the slits 17d formed in the elastic member 17.

However, according to experiments by the present inventor, the elastic material layer 17ba may be made of not only the foamed nitrile rubber but also nitrile rubber, fluorine rubber, silicone rubber, etc. Good results were also obtained. Further, the elastic material layers 17b and 17c may be made of any rubber material as long as they are not easily welded to the elastic material layer 17b during welding of the material to be processed.

An elastic member is attached and a slit is formed on the opposing surface. Even when welding a workpiece having a step, each elastic member divided by the slit deforms according to the shape of the step. To obtain an ultrasonic processing machine capable of performing complete welding, which is favorable in appearance and does not tear a part of the workpiece material at the stepped part because the pressing force on the welded part is made uniform. In addition, damage caused by abnormal expansion of the elastic member can be prevented.
Further, it has a simple structure and can be manufactured at low cost, which provides excellent effects.
