The Composite Machine generally refers to a kind of composite equipment in home textile, clothing, furniture, automobile interior decoration and other related industries. It is mainly used for laminating production process of two or more layers of cloth, leather, film, paper, sponge, etc.

　　Methods to avoid wrinkling of the finished products of the grey paperboard Composite Machine:

　　(1) It is easy to wrinkle the composite film when it is cooled and shrinked. Wrinkling can be reduced by properly reducing the running tension of the substrate.

　　(2) Adjust the flatness of the base material. If the guide rollers assembled on the dry laminating machine have parallelism error, some plastic film base materials are easy to produce wrinkles on the guide rollers.

　　In production, the flatness of the substrate can be adjusted by adjusting the position of the roll. Of course, for personalized printing, we can also add some flattening or bending rollers to stretch the film at the appropriate position before lamination.

　　(3) In the production process, special attention should be paid to the adjustment of the compound pressure between the two composite rollers. The uneven composite pressure, such as too high pressure, is most likely to cause the composite film to wrinkle. In addition, cleaning the composite roller and replacing the damaged rubber roller can also avoid wrinkling of the composite product.
