より適宜選定される。The heating temperature at this time is
It is the temperature at which the surface of 3.14 can be melted and softened, for example,
100 when using polyvinyl chloride as the thermoplastic resin
The temperature is approximately 200° C., and is appropriately selected depending on the thermoplastic resin used.

とが溶融接着するものであれば良い。このシールテープ
６．８のうち少なくとも一方はシートと同し層構成を有
するテープ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°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 solely of the same thermoplastic resin as the sheet. Examples include tape, but the surface of each tape 6.8 and the top and bottom surfaces of each sheet 5,7
Any material that can be melted and bonded is fine. It is preferable to use a tape having the same layer structure as the sheet as at least one of the sealing tapes 6.8 in view of the strength of the joint.
又、このシールテープ６．８のうちシートの一方の面に

う理由からである。Also, it is preferable that the melting point of the tape supplied to one side of the sheet is higher than the melting point of the tape supplied to the other side of the sealing tape 6.8. For example, in the case of polyvinyl chloride resin, one side is 150~200℃, the other side 100~
It is preferable to set the temperature to 150°C. The reason for selecting tapes 6.8 with different melting points in this way is to
, 7 and 7 at the same time, there is a problem that if the melting point is the same, the sheet thickness at the joint part of the sheets tends to become thinner, and the strength of the joint part becomes weaker. This is because the molten resin easily penetrates into the gap formed at the end of the sheet, and the effect of maintaining airtightness is better.
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、０．５〜３１
程度が好ましく、又幅としては１〜ｌＱｃｍ程度が適当
である。The thickness, width, etc. of the tapes 6 and 8 can be appropriately selected depending on the thickness of the sheets to be joined, etc., but the thickness is 0.5 to 31 mm.
The width is preferably about 1 to 1Q 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
様な熱風ヒーターに限らず、熱ロール或いは輻射熱を利
用するヒーター等テープとシートを同時に加熱可能なも
のであればいずれも使用可能である。Further, the heating means in the present invention is not limited to the hot air heater shown in the above embodiments, but any means that can heat the tape and sheet at the same time, such as a hot roll or a heater using radiant heat, can be used.

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 to both sides of the joint, the joint strength is strong and the joint can be made with excellent airtightness at the joint. Therefore, the joining method of the present invention is particularly effective when manufacturing gas-filled items such as boats, floats, flexible containers, simple baths, and air-supported tents using tarpaulin sheets.
