Abstract
A system for bonding films includes a first film, a second film having a plurality of elements, a bonding roller, and a deformable roller having a deformable outer layer. The stiffness of the second film is less than that of the first film. By using the system, the deformable outer layer of the deformable roller produces enough deformation during bonding films to fill the area not covered by the plurality of elements on the second film. Therefore, the second film without sufficient stiffness and the first film can be bonded with each other to produce a composite film without wrinkles. A method for preparing a composite film using the system is also disclosed.
Claims9
A system for bonding films, comprising:
- a first film, having a first surface and a second surface opposed to the first surface;
- a second film, with a stiffness less than that of the first film and having a first surface and a second surface opposed to the first surface, a thickness of the second film being less than that of the first film, wherein
- the first surface of the second film is configured to orientate to the first surface of the first film, and
- the second surface of the second film includes a plurality of elements and at least one gap space uncovered by the elements, each gap space being located between two adjacent elements of the plurality of elements on the second film;
- a bonding roller, configured to contact the second surface of the first film;
- and
- a deformable roller, configured to contact the second surface of the second film and disposed adjacent the bonding roller, wherein the deformable roller has a deformable outer layer and the deformable roller produces deformation to fill the at least one gap space on the second surface of the second film, wherein
- the bonding roller is configured to indirectly contact to the deformable roller via the first film and the second film,
- the deformable roller is configured to indirectly contact to the bonding roller via the first film and the second film, and
- the bonding roller has a Shore A hardness greater than that of the deformable roller.
