喰込んで溶着する。 Therefore, a mesh tube is arranged between the lower surface of the collar 2a of the main cylinder and the upper surface of the peripheral edge of the bottom plate, the main cylinder is pressed toward the upper end of the mesh tube, and the bottom plate is pressed against the lower end of the mesh tube,
Coil 9 connected to high frequency generator 8 in this state
A high-frequency current is passed through the coil (Figure 3). As a result, the high-frequency current flowing through the coil generates an induced current in the metal mesh tube, causing the mesh tube to rapidly generate heat. Each surface of the upper surface of the peripheral portion is melted, and the upper end 6a and lower end 6b of the mesh tube are bitten therein. In practice, 2 to 5 seconds is enough time for high-frequency current to flow through the coil, so after that, stop flowing the current, wait for it to cool down, and once it has cooled down, release the pressure between the main cylinder and the bottom plate. As a result, the upper end 6a and lower end 6b of the mesh tube are slightly bitten into and welded to the lower surface of the collar 2a of the main tube and the upper surface of the peripheral edge of the bottom plate.
高周波誘導加熱を行なつている間、網筒を内側

出せばよい。 When it is necessary to spread out the mesh tube from the inside during high-frequency induction heating, for example, as shown in FIG. The mesh tube 6 is fitted onto the outer periphery of the cylindrical portion 10' of the cylindrical portion 10 of the three-part jig 10b, and stretched to a predetermined state.After cooling and welding the mesh tube, the diameter piece 10a is pulled upward from the main tube, and then Then, the two arcuate pieces 10b, 10b can be pulled out upward from the main cylinder.
しかし、第５図に示すように筒壁２ｂの内側

補助筒壁２b′と５b′を主筒と底板に形成して置け
ば、網筒の上下各端部を筒壁と補助筒壁の間に挿
入して主筒と底板を上下から押付ければよいの
で、この場合は治具を使用する必要がなくなる。 However, as shown in FIG. 5, auxiliary cylinder walls 2b' and 5b', which fit on the inner periphery of the net cylinder, are formed on the inside of the cylinder wall 2b and the cylinder wall 5b, respectively, and placed on the main cylinder and the bottom plate. For example, it is sufficient to insert the upper and lower ends of the mesh tube between the tube wall and the auxiliary tube wall and press the main tube and the bottom plate from above and below, so there is no need to use a jig in this case.
