The TAPPI TIP 0304-07 standard mainly discusses the phenomenon of transverse warping of corrugated fibreboard and its correction method. Transverse warping refers to the warping deformation of corrugated fibreboard in the direction parallel to the corrugated groove (that is, the direction of the paper roll's width), which will affect the stacking, printing quality and subsequent processing of Cardboard. The standard analyzes the causes of warping, such as the inconsistent water content of the tissue and the inner paper, the uneven moisture and temperature of the corrugated fibreboard in the production process, and provides corresponding solutions, such as adjusting the paper tension, controlling the preheating and water spraying, and optimizing the operating conditions of the equipment. Through these methods, the lateral warping of corrugated fibreboard can be effectively reduced, and the product mass and production efficiency can be improved.
