Claims (3)
- 樹脂押出機から成形ダイスを通じて押出成形された熱可塑性エラストマ樹脂を主原料とする断面が略下向きC字形をした帯状の押出成形品に対する寸法を調整するための治具であって、
上記押出成形品の天井部の内面側を支持する受け台と、上記押出成形品の天井部の両端からそれぞれ略半円形状に内側に湾曲した一対の側縁部を押圧する押圧具と、この押圧具を上記受け台に対して近接離間するようにスライドさせるスライド機構と、を備えることを特徴とする押出成形品の寸法調整治具。 - 上記押圧具は一対の側縁部を個々に押圧するように左右2つ設けられており、また上記スライド機構は、各押圧具を独立してスライドさせるように各押圧具に対して個別に設けられていることを特徴とする請求項1記載の押出成形品の寸法調整治具。
- 請求項1または請求項2に記載の寸法調整治具を使用した押出成形品の製造方法であって、
樹脂押出機から成形ダイスを通じて押出成形された押出成形品を構成する熱可塑性エラストマ樹脂の温度が少なくとも100℃以上である位置に上記寸法調整治具を設置し、押出成形品の上記天井部の内面側を上記受け台で支持しつつ、上記各押圧具の位置を上記受け台に対して近接離間させることにより、上記押出成形品の上記天井部に対する上記側縁部分の距離を調整することを特徴とする押出成形品の製造方法。
