Abstract

A film treating method includes feeding a film from a film feeder, moving the film along an outer circumference of a fixed support unit, which supports the film and guides the movement of the film, applying tension to the film by moving a variable support unit from a first surface of the film toward a second surface of the film, processing the film, and collecting the film.

First claim

What is claimed is:

1. A film treating method comprising:
feeding a film from a film feeder;
moving the film along an outer circumference of a fixed support unit which supports the film and guides the movement of the film, wherein the fixed support unit comprises:
a first fixed roller separated from the film feeder in a first direction,
a second fixed roller separated from the first fixed roller in a second direction different from the first direction, and
a third fixed roller separated from the second fixed roller with a film processor interposed therebetween;

applying tension to the film by moving a variable support unit from a first surface of the film toward a second surface of the film, wherein the variable support unit comprises:
a first moving roller disposed between the film feeder and the first fixed roller,
a second moving roller disposed between the first fixed roller and the second fixed roller, and
a third moving roller disposed between the third fixed roller and a film collector;

processing the film by using the film processor; and
collecting the film by using the film collector.

2. The method of claim 1 , wherein a first line segment connecting the film feeder and the first fixed roller, a second line segment connecting the first fixed roller and the second fixed roller, and a third line segment connecting the third fixed roller and the film collector are defined, wherein the first moving roller moves across the first line segment, the second moving roller moves across the second line segment, and the third moving roller moves across the third line segment.

3. The method of claim 1 , wherein the film feeder feeds an ACF which comprises a film layer and a support layer, and the film processor comprises a bonding unit which attaches the film layer of the ACF to a target object.

4. The method of claim 1 , wherein the film processor changes at least one of physical or chemical properties of the film by performing a treatment on the film.

5. The method of claim 1 , wherein the film processor coats the film with a material or forms a film stacked structure by attaching another film onto the film.
