Title
(JA) 配管補修用乾式ライナの製造方法及び装置
Abstract
(JA)

【課題】ライナの外径は、損傷した管の内径と実質的に同じであるため、織物層の幅は、補修される管の直径に合わせてカスタマイズしなければならない。このため、通常、ライナメーカーは、異なる直径の管に適したライナを製造するために数多くの異なる幅の織物層を備蓄することになる。
【解決手段】配管補強用ライナの製造方法が、第1の方向に延びる連続的な第1の補強用繊維を供給するステップと、第1の方向が機械方向と平行であるように第1の補強用繊維を機械方向に移動させるステップと、第2の方向に延びる第2の補強用繊維を有する材料のシートを供給するステップと、第2の方向が第1の方向と実質的に垂直であるように移動中の第1の補強用繊維上にシートを配置するステップと、シートを閉じた形に折り畳むステップとを含む。
