A corrugator for producing double and single wall corrugated board structures including two pairs of interlocking corrugating (31, 32, 33, 34) rolls. The spacing between the flutes of the corrugating rolls of one pair of interlocking corrugating rolls is an integral multiple of the spacing between those of the other pair. The adjacent center rolls are synchronized so that when rotating about their respective axes the flute crests of one roll are aligned with flute crests of the other. A pressure roll is disposed to apply pressure to one of the corrugating rolls for bonding a center liner to the flutes of one corrugating medium, whilst the flutes of the other corrugating medium are bonded to the center liner as it passes between the two center rolls. Also disclosed is a liner application station for bonding outer liners to the two corrugating media. |
