従来技術 西ドイツ国特許第732156号明細書により公知
の、２つの熱可塑性合成材料の薄片を重ねて溶着
するための合成材料の溶着機械は、電気的に加熱
された１つの加熱くさびを有し、この加熱くさび
は溶着過程において薄片と絶えず接触している。
加熱くさびの後方にこれと僅かな距離を隔てて配
置され駆動されている１対の押圧ローラーは薄片
を絶えず運搬しそして軟化した薄片の部分を押圧
し、そのことによりこれらの薄片は互いに均一に
結合される。加熱くさびは銀で造られ従つて熱伝
導の非常に良い材料から造られている。この様に
して加熱くさびから薄片に比較的素早い熱伝導が
行われ、斯くして溶着過程は比較的大なる送り速

この様な種類の溶着機械は特定の熱可塑性の合
成材料、例えばPVCの薄片を溶着するのに有用
であることが実証されている。何故ならば一方で
は溶着接目が平坦でそして歪められることがなく
形成され、他方では溶着接目に境界を接している
縁の部分にも何等の歪みが生じないからである。
これに反してポリエチレン及びポリプロピレンの
薄片を溶着する場合には、溶着接目の縁及び溶着
接目に接している縁の部分に波状の変形が生じ、
この変形は外観及び場合によつては溶着された対
象物の使用可能性が著しく阻害される。
これらの合成材料の薄片の相異なる溶着状態は
次の理由によるものである。即ち、PVCは無定
形の組織に構成され、ポリエチレンやポリプロピ
レンはそれに反して部分的に結晶性をもつ組織に
構成されているからである。部分的に結晶性を有
する組織の場合は無定形の組織とは反対に、溶着
接目が加熱され軟化した形態で、この接目に直接
接している縁の部分も組織の変化が生じ、この変
化は引き続いて行われる冷却過程において元に戻

組織に戻るのが妨害される可能性がある。このた
め上記した様な波状の変形が発生する。
目 的 本発明の目的は、部分的結晶性の組織を持つ合

くとも３つの部分に分割されていること、これら
のうち中央部分が高い熱伝達能力を有する材料か
らなること、そして外側に位置する部分が低い熱
伝達能力の材料からなることにより達成される。
加熱くさびの熱伝達能力は、中央部分にて高
く、外側に位置する部分にて低くするという構成
によつて、溶着される合成材料の薄片は加熱くさ
びの中央部分ではこの部分がエネルギーの流動が
大であるため強く熱せられそして縁の部分ではエ
ネルギーの流動が僅かであるためあまり熱せられ
ない、従つて溶着が行われている時、加熱くさび
の範囲の軟化した薄片部分と加熱くさびの側方に
位置する薄片部分との間に急激な温度の違いが存
在せず、あまり急激でない、最も好都合な場合に
