ABSTRACT:
A method and apparatus for improving overall quality and reducing warp in corrugated paperboard blanks by controlling a number of interrelated production factors in the production of a double-face corrugated paperboard web from which the blanks are made including the selection of product variables, production of the web, observation of warp characteristics, and adjustment of production factors affecting warp characteristics. Apparatus for controlling warp characteristics includes water sprays at various points along the production apparatus, tensioning devices for various lamina of the composite web, wrap devices for controlling heat supplied to the lamina, adhesive-gap control devices affecting moisture content of the lamina, pressure and flotation devices for controlling heat exposure time of the web, and feedback devices for automatically maintaining selected relationships between the production factors as a function of production speed.
