Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.
[0018] When coating the laser film, at least one of the two sides of the laser film along the moving direction is not coated with paint, so that the laser film has a thickness difference; when the roller squeezes the laser film, because the side of the laser film is thinner than the middle , so the pressure will be transmitted to the side, so that there will be no wrinkles in the middle part of the laser film.
[0019] In order to transmit pressure quickly, the two sides of the laser film along the transmission direction are not coated with paint, and after coating, the thickness of the two sides of the laser film is smaller than the thickness in the middle.
[0020] In order to prevent the coating on bo...
