Title:
COATING APPARATUS
Document Type and Number:
Japanese Patent JPS5624067
Kind Code:
A
Abstract:
A coating apparatus for coating a moving web is disclosed. A scraper element is provided, transverse to the direction of travel of the web, for scraping excess coating material therefrom. The scraper element has three positions: a rest position, in which it is relatively distant from the web; a ready position, in which it is maintained a short distance from the surface of the web, preferably about 1 mm; and an operating position, in which it is pressed against the web. A positioning member includes a first subsystem for moving the scraper element from the rest position to the ready position and a second subsystem for moving the scraper element from the ready position to the operating position. The second subsystem preferably contains a pneumatic pressure element, and the first includes either a pneumatic or a hydraulic pressure element. The two subsystems are connected to each other in series. Adjustable stops are preferably provided to limit the motion of the scraper element toward the web, thereby defining the operating position. In the preferred embodiment, independently adjustable stops are provided at both ends of the scraper edge, so that the pressure of the scraper element on the web can be made to vary across the width thereof.
