GROOVED BELT FOR CORRUGATING MACHINE FOR MANUFACTURING DOUBLE-LAYERED CORRUGATED CARDBOARD Russian patent published in 2009 - IPC B31F1/28 

FIELD: packing industry.

SUBSTANCE: belt for corrugating machine includes main interweaving which has internal and external surface and machine direction or direction of movement in machine, and direction, which is transversal to machine direction. Main interweaving is formed by means of threads located in direction which is transversal to machine direction. Belt also includes liquid resin coating, applied on external surface of main interweaving and hardened. Coating from polymer resin forms layer on external surface of main interweaving. In addition belt contains a lot of grooves, formed in polymer resin coating, grooves favouring cardboard separation and increase of rate of moister removal from cardboard. Claimed group of inventions also relates to belt, containing polymer resin coating in which a lot of holes are formed.

EFFECT: claimed group of inventions ensures creation of belt which possesses improved qualities as to moisture removal and improved qualities as to cardboard separation.
