Abstract: front page image
(EN)Method and apparatus (32) for crushing a portion of a corrugated sheet (10) in an area (20), 22) extending transversely to the corrugations in the sheet without blocking the passages (14) between the crowns (12) of the uncrushed portions of the corrugated sheet (10). In accordance with the method, spacing members (58-66 and 78-88) are inserted into each of the passages (14) on either side of a ridge (12) to be crushed, and the ridge (12) between the spacing members (58-66 and 78-88) is crushed before the spacing members (58-66 and 78-88) are withdrawn. The apparatus for crushing the sheet (10) includes opposed die members (34, 36), each having a plurality of blades (58-66 and 78-88) spaced by slots (68-76 and 90-98). The slots (68-76 and 90-98) in each die member (34, 36) progressively decrease in depth and are positioned to receive the blades (58-66 and 78-88) of the opposed die member. A control circuit (46) causes the die members (34, 36) to engage each time a passage (14) in the corrugated sheet (10) is aligned with a blade (58-66 and 78-88) in a die member (34, 36).
(FR)Procede et appareil (32) pour ecraser une portion d"une feuille ondulee (10) dans une zone (20, 22) s"etendant transversalement par rapport aux ondulations de la feuille sans bloquer les passages (14) entre les couronnes (10) des parties non ecrasees de la feuille ondulee (10). Selon ce procede, des organes d"espacement (58-66 et 78-88) sont inseres dans chacun des passages (14) de chaque cote d"une arete (12) a ecraser, et l"arete (12) entre les organes d"espacement (58-66 et 78-88) est ecrasee avant que les organes d"espacement (58-66 et 78-88) ne soient retires. L"appareil d"ecrasement de la feuille (10) comprend des organes de matrice opposes (34, 36), chacun ayant une pluralite de lames (58-66 et 78-88) espacees par des fentes (68-76 et 90-98). Les fentes (68-76 et 90-98) dans chaque organe de matrice (34, 36) diminuent progressivement en profondeur et sont positionnees pour recevoir les lames (58-66 et 78-88) de l"organe de matrice oppose. Un circuit de commande (46) provoque l"engagement des organes de matrice (34, 36) a chaque fois qu"un passage (14) dans la feuille ondulee (10) est aligne avec une lame (58-66 et 78-88) dans un organe de matrice (34, 36).
