Cause analysis of material wrinkling in production process of composite machine

  Composite machine is a machine that heats two or more layers of the same or different materials, such as cloth and cloth, cloth and paper, cloth and artificial leather, as well as all kinds of plastic and rubber sheets and coils, etc., to a melting or semi melting state, or combines them with a special adhesive. It can be compounded with paper, film, sponge, cloth, etc.

Composite Machine

  Composite paper wrinkling is due to the uneven tension in the process of composite processing, which leads to the paper shrinkage, and the amplitude is not the same, which forms the situation of wrinkling.

  In the production process, special attention should be paid to adjusting the compound pressure between the two compound rolls. The compound pressure is uneven, such as too high pressure, which is easy to cause wrinkling. Wrinkling can be reduced by properly reducing the running tension of the material.

  During the use of the composite machine, the amount of glue should be appropriately increased. If the amount of glue is too small or part of the surface of the substrate is not coated with adhesive, it will cause the two substrates to be difficult to fit together. If the temperature is too high or too low, the bonding fastness of the composite film will be affected.
