Abstract
Official abstract text for this publication.
Provided is an ultra large-width coating device applied to a consecutive process. More particularly, the present invention relates to a coating device capable of maximizing productivity by consecutively manufacturing a large-width film without reducing physical properties of the manufactured film by overcoming a problem in that a coating width is limited during a coating process using the existing contact type coating roller, and a method for manufacturing an ultra large-width membrane using the same.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a membrane, comprising: forming a base film by stretching a sheet; coating a coating solution on one side or both sides of the base film; drying the coated film; slitting the dried film in a longitudinal direction; and winding the slit films, respectively, wherein the coating uses a transfer roller having two or more contact type coating rollers integrated by a connector, wherein the connector is formed at an end of the coating roller, wherein a length of the coating roller is larger than 2,000 mm, wherein a thickness of the connector is smaller than a diameter of the coating roller, and wherein the connector has a length of 2 to 5% with respect to a length of the transfer roller. 2. The method of claim 1 , wherein in the slitting of the coated film in the longitudinal direction, the coated film is slit parallel to the longitudinal direction of the film at a part where the coated film abuts the connector. 3. The method of claim 1 , wherein the coating roller is selected from the group consisting of a gravure roll, a wire bar, a micro gravure roll, a Meyer bar, a nano coater and a DM coater.
