[0002] A film is a thin and soft transparent sheet made of plastic, adhesive, rubber or other materials, and is widely used in industries such as electronics, machinery, printing, etc. For example, in the production process of TAC film in optical films, embossing and edge printing treatment is required to form a gap in the middle area between the upper and lower films to form an air film, reducing the imprinting and friction between the films. However, after the film is embossed, the two edges of the film may warp, resulting in uneven coating in the subsequent coating process. Severe warping may even cause coating peeling, reducing the product quality of the film. For this reason, we propose a film ironing device. Summary of the Utility Model
