Description
2組のかみ合い機構間に積層物を通すために、積層物がウェブの形態に展開されるステップを含み、2組のかみ合い機構の歯が、積層物をその幅の方向に引き伸ばすために、積層物の平面に垂直な方向に互いにかみ合う方法であって、
特にテンショナ(tensioner)ロールを、特に2組のかみ合い機構の下流に提供することによって、かみ合い機構間での展開の間に、ウェブに、縦断方向または縦方向の張力が与えられるステップ
を含むことを特徴とする方法が提供される。
パラメータは次の通りに選択される:
ジョー間距離:20mm
機械速度:254mm/分
サイクル数:2
製品の伸び:定速で100%
SET=L1−L10
L0:試験の開始時、すなわち最初のサイクルの開始時におけるX軸との交点(伸び(%))
L1:元の位置へ戻り、60秒待った後の2回目のサイクルの開始時におけるX軸との交点(伸び(%))
積層物が得られたら、次いでこれを活性化にかける。すなわち、弾力性のない2枚の不織材料間に閉じ込められた弾性フィルムの弾性能力を解放させる。
