A paperboard corrugating machine for forming board having two corrugated mediums joined at their flute tips without any intervening liner. The machine comprises a frame (11) thicker than conventional frames, mounted on which is a second frame (12). Frame (11) carries two rolls (13 and 14) and frame (12) carries two rolls (15 and 16). Frame (12) can be locked into position and loaded against the upper roll (13). The four rolls (13, 14, 15 and 16) lie in a single plane. By using one frame to mount all four rolls (13, 14, 15, 16) and including one pair of rolls (15, 16) on a second frame (12) mounted on the first frame to form a cassette, movement and twisting of the rolls (13 and 15) relative to each other, between which the fluted mediums are aligned flute tip to flute tip, is reduced.
L'invention a trait à une machine à onduler du carton permettant de produire un carton pourvu de deux supports ondulés se rejoignant sur les extrémité de leurs cannelures sans l'intervention d'une quelconque couverture. La machine comporte un châssis (11) plus épais que les châssis conventionnels, monté sur ce qui constitue un second châssis (12). Le premier châssis (11) et le second châssis (12) portent chacun deux rouleaux (13 et 14; 15 et 16). Il est possible de verrouiller le second châssis (12) dans une certaine position et de le faire s'appuyer contre le rouleau (13) supérieur. Les quatre rouleaux (13, 14, 15) et (16), respectivement, se trouvent sur un seul et même plan. En utilisant un châssis pour monter les quatre rouleaux (13, 14, 15, 16) et en installant deux rouleaux (15, 16) sur le second châssis (12) lui-même monté sur le premier afin de former une cassette, on réduit le déplacement et la torsion des rouleaux (13 et 15) l'un par rapport à l'autre, les supports cannelés étant alignés entre ces rouleaux, extrémité de cannelure contre extrémité de cannelure.
