Abstract

La présente invention se rapporte à des appareils et à des processus d'ouverture et d'étirement d'une bande. Selon un mode de réalisation, le procédé consiste à introduire une bande dans un espace qui est formé entre au moins deux cylindres qui s'emboîtent. Le premier cylindre est un cylindre d'ouverture à lames rotatives à arêtes surélevées et le second cylindre est un cylindre annulaire ; les deux cylindres comprennent des arêtes et des rainures. Le premier cylindre comprend une pluralité de dents espacées s'étendant vers l'extérieur depuis la surface supérieure des arêtes, lesdites dents possédant des pointes, la surface supérieure desdites arêtes étant disposée entre les pointes desdites dents et la surface inférieure desdites rainures. Ces appareils et processus permettent la formation d'une bande qui comprend des ouvertures ayant une superficie ouverte plus grande que celle pouvant être obtenue auparavant avec les processus et les appareils classiques.
