In the method of the present invention, a tape is supplied to the upper and lower surfaces of the joining ends of each sheet to heat and melt the tape and the sheet, and the sheet and each tape are simultaneously joined and integrated by joining the sheets to each other. is there. For example, as shown in FIG. 2, the tape 6 is supplied to the upper surface 5 of the joint portion and the tape 8 is supplied to the lower surface 7 of the joint portion of the sheet 1.

The tapes 6 and 8 and the sheet end portions 13 and 14 are heated and melted by feeding. The heating temperature at this time is a temperature at which the surfaces of the tapes 6 and 8 and the sheet end portions 13 and 14 can be melted and softened, for example, when polyvinyl chloride is used as the thermoplastic resin.
The temperature is about 0 to 200 ° C., but is appropriately selected depending on the thermoplastic resin used.

を用いることが接合部の強度から好ましい。The material of each sealing tape 6 and 8 used in the present invention is a tape made of the same material as the sheet (that is, a tape having the same layer structure as the tarpaulin type sheet) or a tape made of the same resin alone as the thermoplastic resin of the sheet. The tapes 6 and 8 may be melt-bonded to the upper and lower surfaces 5 and 7 of the sheets. At least one of the sealing tapes 6 and 8 is preferably a tape having the same layer structure as that of the sheet in terms of strength of the joint portion.

という問題があり、また、一方が低融点であればシート
端部に形成される間隙に溶融樹脂がしみ込み易く、気密
保持の効果がより良好であるという理由からである。The melting point of the tape supplied to one surface of the sheet among the sealing tapes 6 and 8 is preferably higher than the melting point of the tape supplied to the other surface. For example, in the case of polyvinyl chloride resin, one of It is preferable that the temperature is 150 to 200 ° C and the other temperature is 100 to 150 ° C. In this way, the tapes 6 and 8 having different melting points are selected because when the tapes 6 and 8 are simultaneously adhered to the upper and lower surfaces 5 and 7 of the sheet, the sheet thickness of the joining portion of the sheets at the same melting point is selected. Has a problem that the strength of the joint becomes weak, and if one has a low melting point, the molten resin easily penetrates into the gap formed at the edge of the sheet, and the effect of maintaining airtightness is better. It is because there is.
テープ６及び８の厚さ、幅等は接合するシートの厚さ等
により適宜選択できるが、厚さとしては、0.5〜3mm程度
が好ましく、又幅としては１〜10cm程度が適当である。The thicknesses and widths of the tapes 6 and 8 can be appropriately selected according to the thicknesses of the sheets to be joined, but the thickness is preferably about 0.5 to 3 mm, and the width is appropriately about 1 to 10 cm.
又、本発明における加熱手段としては上記実施例に示す

のものの製造に際して特に効果的である。According to the method of the present invention, since the tape is fused on both surfaces of the bonded portion, the bonding strength is high, and the bonding can be performed with excellent airtightness maintaining ability. Therefore, the joining method of the present invention is particularly effective in manufacturing a gas-filled type such as a boat, a float, a flexible container, a simple bath, and an air strut type simple tent using a tarpaulin sheet.
