Claims (7)
- シート状の発泡材を円形に絞りながら樹脂パイプの周りを覆い、紋りきる直前にシート端部を熱風で融解し、かつ電熱コテをシート端部に押し付けて融着し、被覆終了後の径よりわずかに小さい径を持つ中空のダイスに通して融着面を接合し、次いで融着箇所を冷却して固化し、その後中空ダイスより発泡材付きパイプを連続的に引き抜く方法において、樹脂パイプの周囲を覆う発泡材とダイスとの間にナイロンライナーを発泡材の外周表面の80%以上覆うように挟み込ませ、これを発泡材付きパイプと同時に引き抜くことを特徴とする発泡材付きパイプの製造方法。
- 発泡材がポリエチレン発泡材である請求項1記載の発泡材付きパイプの製造方法。
- ナイロンライナーの厚みは発泡材の厚みの1/10以下である請求項1又は請求項2に記載の発泡材付きパイプの製造方法。
- ナイロンライナーは発泡材の外周表面をパイプの長さ方向に沿って直線状に覆う請求項1乃至3いずれか1項記載の発泡材付きパイプの製造方法。
- 融着直後に当該箇所を強制冷却する請求項1乃至4いずれか1項記載の発泡材付きパイプの製造方法。
- 発泡材付きパイプを5〜8℃に維持されたダイスの一部に設けられた冷却ゾーンに通すことにより強制冷却する請求項5記載の発泡材付きパイプの製造方法。
- 電熱コテの温度が250〜300℃である請求項6記載の発泡材付きパイプの製造方法。
