ABSTRACT:
A novel catch pan is disclosed for use in apparatus for coating of a support or moving web using curtain coating method and apparatus. The catch pan is used during start-up and shut-down. In use the catch pan is positioned between first and second edge guides and in close proximity to a support. The catch pan includes a main catch pan surface and first and second opposing sides each having a resilient, flexible shim projecting out along the upper edge thereof and into contact with the first and second edge guides, respectively. Each shim strips liquids from the adjacent edge guide, and then directs such liquids onto the catch pan surface during start-up and shut-down without the deposition of excess liquids on the support, web, or coating roller. Means are provided for retracting the catch pan and controlling the falling curtain during start-up, and for inserting the catch pan for intercepting the falling curtain during shut-down.
