Abstract

L'invention concerne un procédé qui permet de former un élément de type feuille et qui comprend : le transport, dans une direction prédéterminée, d'une feuille continue dans laquelle une pluralité d'éléments élastiques sont disposés côte à côte dans une direction CD et fixés à une zone qui correspond au moins à une zone d'étirement élevé, la pluralité d'éléments élastiques étant continus dans la direction prédéterminée dans un état étiré ; la coupe et la contraction de chacun de la pluralité d'éléments élastiques à un point dans la direction de transport dans une zone correspondant à une zone de faible étirement de façon à former la zone d'étirement élevé et la zone de faible étirement. Lorsque la feuille continue passe entre un rouleau de coupe et un cylindre contre-partie opposés l'un à l'autre, une pluralité de lames de coupe disposées sur la surface circonférentielle externe du rouleau de coupe et décalées l'une de l'autre dans la direction CD sont pressées vers le cylindre contre-partie pour couper la pluralité d'éléments élastiques. Une fois que l'un des éléments élastiques est coupé par l'une de la pluralité de lames de coupe, une autre lame de coupe pour couper l'élément élastique suivant sera déjà pressée vers le cylindre contre-partie pendant que l'une de la pluralité de lames de coupe est toujours pressée. Au moins une lame de coupe est positionnée entre l'une de la pluralité de lames de coupe et l'autre lame de coupe dans la direction CD.
