[0002] Currently, composite films are widely used in various fields. They are made of two or more films, such as films made of acrylic and ABS. Composite films need to be heat-sealed using plastic molds. In traditional production, the two films are usually aligned manually and then fed into the plastic mold. Because the films are thin, they are easy to bend and difficult to align when they are fed into the plastic mold. Summary of the Invention
