し、本願の発明者は溶着帯域の強度は冷却の段階が終わ
りに達したことを示す真の基準であることを確認した。
けれども、この強度は冷却期間の長さに直接関係せず、
互いに溶着すべき材料の内部温度に関係する。周囲温度
が４０℃の場合、一定冷却期間の終わりに、溶着帯域内
の材料の内部の温度は、周囲温度が５℃の場合に比較し
３０℃以上も高い。周囲温度の影響を熟慮して考慮する
ことを確認することは本発明方法の基本である。これに
より、溶着帯域内の材料に必要な強度を確保するように
冷却期間を制御することができる。
【００１１】図１は本発明方法を実施する装置の線図的
横断面図である。図１に示す突合せ溶着装置１は熱可塑
性プラスチック材料から成る２個の管２を互いに突合せ
溶着するのに特に適している。管２の前面を符号２ａに

【００１４】本発明方法は一定冷却、及び変化する冷却
のような種々の冷却条件下で溶着帯域の内部の材料温度
を決定する。このようにして、冷却期間の終わりの溶着

によって冷却期間を短くすることができる。次のような
方法により、冷却空気送給装置６によって冷却の効率を
増大することができる。 ・空気ファン（低圧大容量空気）による冷却、又は ・空気圧縮機（高圧小容量空気）による冷却。 このような冷却装置６を突合せ溶着装置１内に組み込む
