Abstract
A coating apparatus includes: a container configured to accumulate a coating liquid; a rotatable coating bar arranged at an opening part so that the coating bar has a clearance between the coating bar and a downstream side end of an upstream side cover and a clearance between the coating bar and an upstream side end of a downstream side cover and a rotation axis direction of the coating bar is directed in a longitudinal direction of the container; a plurality of rotatable supports intermittently arranged along the rotation axis direction of the coating bar; and an in-liquid cover extending in the longitudinal direction of the container.
Claims12
A coating apparatus comprising:
- a container configured to accumulate a coating liquid, the container including an upstream side cover and a downstream side cover dividedly arranged in an upper part of the container on an upstream side and a downstream side in a running direction of a web to form an opening part extending in a longitudinal direction of the container;
- a rotatable coating bar arranged at the opening part so that the coating bar has a clearance between the coating bar and a downstream side end of the upstream side cover and a clearance between the coating bar and an upstream side end of the downstream side cover and a rotation axis direction of the coating bar is directed in a longitudinal direction of the container;
- a plurality of rotatable supports intermittently arranged along the rotation axis direction of the coating bar, the supports supporting the coating bar from below in the container;
- and
- an in-liquid cover extending in the longitudinal direction of the container, the in-liquid cover being arranged between the downstream side cover and the supports, wherein
- in a top view of the coating apparatus, a first range of an upstream side end of the in-liquid cover is overlapped with the supports and is defined as an overlapped range, and a second range of the upstream side end of the in-liquid cover is at least a portion of a range between adjacent overlapped ranges, and wherein
- a clearance between the upstream side end of the in-liquid cover and a surface of the coating bar is wider in the second range than in each of the adjacent overlapped ranges.
