Abstract
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.
Claims10
A coating device, comprising:
- a transfer roller coating a base film with a coating solution;
- a housing including a roller groove that has a part of the transfer roller inserted thereinto to rotate the transfer roller and filled with the supplied coating solution;
- and
- a coating solution supplier supplying the coating solution to the housing,
- wherein the transfer roller has two or more contact type coating rollers integrated by a connector.
A method for manufacturing an ultra large-width membrane, comprising:
- forming a base film by stretching a sheet;
- coating a coating solution on one side or both sides of the base film;
- slitting the coated 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.
