At present, the film-coated rubber rollers used in the society have the following structures: cylindrical surface light shape; cylindrical surface diamond-shaped concave shape; cylindrical surface diamond-shaped mesh convex shape. The basic structure and principle of gluing are shown in Figure I. The arc arrows next to each roller indicate the direction of rotation of the rollers.
  Using the over-plastic method, you need to put photos, pictures, etc. in the plastic film, heat and press, so that the periphery of the plastic film is bonded due to high temperature, and the photos and pictures are sealed by the plastic film. However, in this way, the entire photo and picture will become thicker, hard and straight, and cannot be curled. Once curled, wrinkles and bubbles will appear. In the cold laminating method, a plastic film needs to be placed on the photos and pictures. This plastic film is sticky and can stick to the surface of the photos and pictures. Then it is rolled by a die roller to make the plastic film and the photos and pictures Glue tightly together to protect it.
      The rubber rollers to be used should be cleaned, and the rubber should be wrapped with plastic film and placed on the rubber roller rack. A few of them should not be stacked together or stand against the wall, so as to avoid undue loss of the gel . During the transportation process of the used rubber rollers for processing and casting, please avoid throwing them away or pressing them, and keep the roller core from eccentricity and bending to ensure the normal use of the roller core.
