When the substrate 1 projects 12 cm forward from between the cutters 10 and 11 and the substrate 7 projects 30 cm forward from between the cutters 12 and 13, the male die 14 moves rapidly rightward together with the punch 15 and the foamed resin 16. The cutters 10 and 11 cut the substrate 1, the cutters 12 and 13 cut the substrate 7, and the male mold 1
4 presses the center of the fragment of the substrate 7 through the circular hole of the substrate 1 having a diameter of 8 cm and pushes it into the female die 17, and the substrate 7 is molded into a cup shape by the heat of the female die.

The foamed resin 16 pushes the substrate 1 to the right and presses it against the flange formed by the substrate 7 formed on the left side of the female die 17, so that the low melting point synthetic resin of the substrate 1 is melted by the heat of the female die 17,
The substrate 1 is fused to the flange of the substrate 7. Further, the punch 15 punches out the periphery of the substrate 1 and the substrate 7, and digs a through hole having a diameter of 10 cm.

Shortly thereafter, the male mold 14 and the like moves leftward and returns. At this time, the right surface of the foamed resin 16 which has been compressed pushes the punched ring (strengthening ring) of the substrate 1 to the right for a while. Therefore, the ring of the substrate 1 and the cup-shaped filter substrate 7 in the female mold 17 remain in the female mold 17. The surrounding substrates 1 and 7 punched by the punch 15 are
Although it is fitted around the female die 17, the cylindrical tubes 18 move to the left, push them to the left, come off the female die 17, and fall.

It does not take any trouble to fit it into the external container and can be easily performed. Further, when the conventional bag is cut into short pieces and fitted into the inner container 24, the bag can be easily fitted, but the edges of the bag are washed away by the flow of water, and the bag falls to the bottom of the inner container 24 and becomes useless for the filter.

In the present invention, since the reinforcing ring 26 is strong, it is not deformed by the flow of water, and it can be attached to and detached from the inner container, and it can be used very easily. The above embodiment can be variously modified. The outline is described below. An adhesive is applied to the roller 3 or the like and applied to the reinforcing ring substrate 1 to bond the substrate 1 and the substrate 7, or a ring-shaped metal electrode is attached to the right surface of the foamed resin 16 so that it is between the female mold 17. A high frequency voltage may be applied to heat the substrates 1 and 7 to fuse them.

When the substrate 7 is relatively thick, the reinforcing substrate 1 may be omitted and the substrate 7 may be melted by the heat of the mold 17 and pressed by the foamed resin 16 to form a flange that is difficult to deform. Good. A few small tunnels are gargled in the female die 17, the left side of the female die 17 is opened, a molten synthetic resin is ejected and adhered to the flange of the substrate 7, and the male die 14 and the foamed resin 16 are left and right. It may be rotated around the shaft to spread the fused resin over the entire flange and cure it to obtain a strengthening ring.

The nozzle for ejecting the fused resin is a male mold 1
