20110011522 | 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-facer useful to apply a high-solids content adhesive, also desirable for low-temperature corrugating, is also provided. | 01-20-2011 |

20120255671 | METHOD FOR PRODUCING A MULTI-PLY WEB OF FLEXIBLE MATERIAL - A method for producing a multi-ply web including at least three plies of flexible material, such as paper and nonwoven material, by means of gluing the plies. The method includes the steps of embossing first and second webs of flexible material separately between a respective embossing roll and a respective impression roll; applying glue to one side of each of the embossed first and second webs; feeding the first and second webs and a third web separately into a laminating nip. The third web is between the first and second webs, and the glue is applied to sides of the first and second webs facing the third web so that the first, second and third webs are combined in a single step. The laminating nip is formed between the first embossing roll and a laminating roll. | 10-11-2012 |

Outer protective skins are applied to exterior surfaces of the interior layer to create a multilayered material which is then cut to size. | 10-18-2012 |
20130139959 | PRODUCTION METHOD AND PRODUCTION LINE FOR PRE-PRINTED SURFACE PAPER CORRUGATED BOARDS - The disclosure provides a production method and production line for pre-printed surface paper corrugated boards, and the production method and production line provided by the invention can be used for solving the problem that the existing corrugated board production line and process cannot adapt to the production of pre-printed colorful corrugated boards. In the disclosure, because the bonding mode that surface paper is arranged on a single-face corrugated board is adopted, the direct contact between color-printed paper and a high temperature heating plate of a drying part can be avoided, thereby effectively preventing the damages on the materials, patterns, gloss oil and plastic films of the color-printing paper. The disclosed corrugated board production method and corrugated board production line can effectively adapt to the application requirements of pre-printed colorful paper on the premise of not increasing the cost. | 06-06-2013 |
