Abstract
An extrusion-type coating apparatus for performing a uniform coating on a web by equalizing a flow rate distribution of a coating material along the widthwise direction of the web. The apparatus has a slit in a coating head to pass the coating material from the bottom of the slit to an opening of the same opened on a surface portion of the coating head, a feeder to feed the web on the surface portion in a direction from a front edge to a rear edge of the opening of the slit and a restricting member to restrict a gap of the slit by an insertion of the restricting member into the slit. The restricting member has a thickness pattern along its length so as to equalize the flow rate of the coating material along the length of the slit.
