<p>Multiple ply corrugated or solid fibre paperboard having any desired number of plies is made by adding to the delivery end of conventional corrugator or paster apparatus, between the cut-off section and the stacker section, a glue applicator system controlled, preferably by computer program, to apply glue only to the desired areas of those outfeeding paperboard sheets which are to be bonded together to form the desired multiple ply paperboard. The glued and unglued paperboard sheets proceed to the stacker section where they are stacked one upon another. The paperboard sheets having an interface of glue are bonded together to form the multiple ply end product and the paperboard sheets having no glue interface allow subsequent separation of the plurality of multiple ply corrugated paperboard end products in the stack. Offsetter mechanism is provided to offset corresponding margins of certain plies of a group before depositing them in the stacker, to form a splice joint.</p> |
