Regarding a welding machine that avoids welding sheets 1 to 1-shaped processing materials to each other, in particular, the welding machine is equipped with a transfer device such as an I]-ra for transporting the welded sheets and the sheet-shaped processing materials in one direction, This article concerns a welding machine that performs continuous welding on these sheet-like processed materials.

After applying heat to the sheet 1-shaped processed material passing through the sheet 1, the sheet 1-shaped processed material is pressed and held between a pair of opposing rollers, and the rollers are rotated in one direction.

近傍で溶融されてしまったりすることもあった。However, in the conventional system R6 described above, radiant heat is indirectly applied to the sheet 1 to the processed material 1 passing close to a heat source such as a heater, so the thermal efficiency is low. If the co-feeding speed of the processed material to be passed through is divinely determined, the optimum heat can be applied approximately evenly to the sheet-shaped processed material, but if the feeding speed is changed or stopped midway through, In such cases, even if you change the set temperature of the heater, etc., the heater temperature will not be changed quickly, so it will not be possible to apply optimal and uniform heat to the processed material, and the supply speed will be extremely low. When the temperature is lowered, the processed material may be melted near the heater.

The frictional heat generated in the processed material 1
There has been provided an ultrasonic welding machine that welds a sheet material by pressing heated processed materials together using a heating method.

時間を要する等の問題点を有り−るものであった。However, in the above ultrasonic welding machine, ultrasonic vibrations are applied to the overlapping surfaces of the processed materials polymerized by the working surface of the processing horn subjected to ultrasonic vibrations, and the overlapping surfaces are caused to generate ultrasonic heat and mutually contact each other. Since welding was done, if the material on the first side of the processing horn is thick, or if the material to be processed is made of a relatively soft material, Because sufficient ultrasonic vibration cannot be applied to the polymerization surface, the above! The I-polymerization surface d3 was not sufficiently heated and could not be subjected to the R8 bonding process. Furthermore, not only is the vibrating element for applying ultrasonic vibrations to the machining horn expensive, but also the design of the machining bone requires a great deal of time.

A conductor is mounted on a part of the roller, which is placed opposite to a support member for supporting the processed material, and generates an eddy current in the conductor to avoid heat generation. By installing an electric I6 induction system including an electromagnetic coil and driving the roller in one direction, it is possible to improve the control of the temperature of the roller. The purpose of the present invention is to provide an electromagnetic induction welding method that can improve thermal efficiency and can also be applied to processed materials made of 41 different materials.

代用し得ることは明白である。In the above embodiment, a processing horn 4 including a processing section 5 as a support member for supporting the processing material is subjected to ultrasonic vibration, and the processing material W is held between the processing section 5 and the presser roller 6. The processing material W and the sewing tape 19 are bonded to each other by the synergistic effect of the heat generated by the ultrasonic heat generation and the heat generated by the combined current loss of the annular body 6b of the vortex presser roller 6 on the overlapping surfaces of the sewing tape and the sewing tape 19. Although we have shown an example in which a good welding process is applied to the material, the supporting member may be any member that has a supporting surface that supports the processed material 4 even if it is not necessarily subjected to ultrasonic vibration. It is obvious that they can be substituted.
