Abstract
Abstract of the Invention Improvements in Corrugating Machines A machine for making corrugated board comprising means to feed two separate wob? (W1;W2) between two respective pairs of corrugating rolls (1,2; 3,4) to form two corrugated layers, a first adhesive applicator (5) for applying adhesive to the peaks of at least one of the two corrugated layers, means (2;3) to bring the two corrugated layers together at the peaks of the corrugations, means (8) to convey the joined corrugated layers past a second adhesive applicator (12) for applying adhesive to the exposed peaks of one of the corrugated layers, and means (22) to apply a liner web (W3) to the corrugated layer having the adhesive on its peaks, and including means (21) for pneumatically urging the corrugated layers into contact with the second adhesive applicator as the joined layers move past the second adhesive applying means.

Adheslve ls applied to the :;
peaks of the corrugattons by an appllcator roll 5 and the corrugated ~ebs W1, ~2 are brought together between the rolls 2 and 3. Ihe webs Wl,W2 are he1d to thelr respectlve rolls 2,3 by suctlon appl1ed through chambers 6 and 7 respectlvely.

5. A machine according to claim 4 in which the second-mentioned roll (3) includes a pressure chamber (11) from which air pressure acts to assist the transfer of the joined corrugated webs onto a further roll (8) arranged to carry the joined webs towards the second adhesive applicator (13).
6. A machine according to any one of claims 1 to 5, including one or more heaters (23,25) adjacent to the means (8) for carrying the joined corrugated webs (W1,W2) and the applied liner web (W3) for promoting the bonding of the liner web (W3).
7. A machine according to claim 6 in which the heater or heaters (23,25) and the second adhesive applicator (12) are mounted on one or more subsidiary frames separate from the main frame of the machine, and including means (33,39) for moving the subsidiary frame or frames automatically away from the roll or other means (8) arranged to carry the joined corrugated webs past the second adhesive applicator.
