Slot applicator

Abstract

The purpose of this invention is to provide a slit-type coater that can suppress uneven spray volume at the beginning of coating liquid spraying. Specifically, the slit-type coater of the present invention for solving the above-mentioned problems includes: a nozzle that is formed elongated in one direction to spray a coating liquid; a coating flow path including a manifold for storing the coating liquid and a slit connecting the nozzle and the manifold to supply the coating liquid to the nozzle; and at least one adjusting rod, which is used to adjust the volume of the coating flow path by displacing it along the gap direction of the slit wall, which is orthogonal to the gap direction of the slit formed by the length direction of the nozzle before the slit is formed; and the slit-type coater sprays the coating liquid from the nozzle to coat the object to be coated; and is configured such that when the coating liquid is filled into the coating flow path, the origin position of the adjusting rod is set to a position such that the gap between the adjusting rod and the slit wall in the gap direction is greater than the gap between the adjusting rod and the slit wall in the gap direction.
