Abstract

本発明は、積層体の幅方向の端部に適正な断面形状をしたエッジ部を形成することにより、複雑な制御装置を必要とせず、各層の厚みが幅方向に対して一様で、高精度に積層された積層シートを容易に製造するものである。 複数種類のシート材料を積層した積層体の幅方向の端部のうち少なくとも一方にエッジ材料をエッジ部として合流部において付加する積層シートの製造装置であって、前記合流部における前記エッジ材料の各流路の流路方向に対して垂直な断面形状を積層方向に１０等分する直線で分割した各領域の面積を積層方向の中央部から積層方向の端部へ向かってＳｎ（ｎ＝１，２，３，４，５）としたとき、式（１）および式（２）の関係を共に満足する。 Ｓ１≦Ｓ２≦Ｓ３≦Ｓ４≦Ｓ５ ・・・（１） Ｓ１＜Ｓ５ ・・・（２）
