Abstract
A network-based system and method for providing desired moisture set point values for individual papers lines based on the physical properties of each liner and the atmospheric conditions associated with a corrugator is disclosed. The desired moisture set point values are based on the hygroexpansivity of each individual paper liner. Once the moisture set point value has been determined, a conditioning apparatus adjusts a moisture value for each liner in order to tune the post-warp characteristics of the final corrugated product.
Claims21
A method of producing a corrugated product, comprising:
- with respect to a first face-sheet web:
- a. adjusting a moisture content in the first face-sheet web to a first range of greater than 10 wt. % and up to 20 wt. % by applying a first thin film of liquid to a first surface thereof;
- b. thereafter heating the first face-sheet web;
- and
- c. thereafter bonding the first surface of the first face-sheet web to a first side of a fluted medium.
A network-based system for producing a corrugated product comprising a central site adapted to receive, via a global computer network, corrugator input data sets relating to a plurality of remote corrugating operations from a plurality of remote corrugator control terminals associated respectively therewith, each said remote corrugator control terminal being adapted to collect the corrugator input data set related to the respective corrugating operation;
- the central site comprising data-storage means for storing the corrugator input data sets and a processor adapted to evaluate the corrugator input data sets and determine respective hygroexpansivity attribute values therefrom, the processor being further adapted to assign moisture-conditioning setpoints for the respective corrugating operations based on said hygroexpansivity attribute values.
