METHOD FOR MOISTURE AND TEMPERATURE CONTROL IN CORRUGATING OPERATION
A method of producing a corrugated product comprises the steps of providing at least one medium conditioning apparatus upstream of at least one of a corrugating labyrinth, single-facer, and/or double-backer. The moisture content in at least one of a web of medium material, first face-sheet, and/or second face-sheet is adjusted to be in the range of 6-9 wt.% moisture by applying a substantially continuous thin film of liquid thereto using the at least one medium conditioning apparatus. In one example, at least one heating arrangement is arranged downstream from the at least one medium conditioning apparatus to heat at least one of the web of medium material, first-face sheet, and/or second face-sheet.

METHOD AND APPARATUS FOR PRODUCING A CORRUGATED PRODUCT
A method and apparatus are useful to produce a corrugated product. They can be used to produce a corrugated product at low temperature, such as room temperature. A zero-contact roll is used to support a web of medium material on a cushion of air at a location prior to the web entering the corrugating labyrinth. The web is free to move toward or away from the surface of the zero- contact roll, on the cushion of air, in response to small oscillatory changes in downstream tension demand based on the fluting frequency in the corrugating labyrinth. A mechanism is also provided to precisely control the mean tension in the web prior to entering the corrugating labyrinth at a low value. Thus, mean web tension is precisely controlled and is low, tension oscillations can be damped, and low temperature corrugating can be achieved without significant fracturing in the corrugated web. A single-face useful to apply a high-solids content adhesive, also desirable for low-temperature corrugating, is also provided.
A corrugator glue machine is provided having a web tension nulling mechanism that is effective to cancel out web tension-effect forces exerted on machine members, such as rollers, so these forces to not substantially interfere with the application of glue to the exposed flute crests of a single-faced corrugated web in the glue machine.
