PCT No. PCT/AU97/00151 Sec. 371 Date Sep. 11, 1998 Sec. 102(e) Date Sep. 11, 1998 PCT Filed Mar. 12, 1997 PCT Pub. No. WO97/33746 PCT Pub. Date Sep. 18, 1997A paperboard corrugating machine for forming board having two corrugated mediums joined at their flute tips without any intervening liner. The machine comprises a relatively heavy main frame (11) and a second frame (12) which is mounted for movement on the main frame. The main frame (11) carries two rolls (13 and 14) and the second frame (12) carries two rolls (15 and 16). Frame (12) can be locked into position and loaded against the upper roll (13), and the four rolls (13, 14, 15 and 16) lie in a single plane when the rolls are operational. With this construction, 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.
