SQUEEGEE-SWITCHING DEVICE IN SCREEN PRINTING MACHINE

摘要

PURPOSE:To prevent an ink from partially dripping onto the surface of a screen machine plate during turning-back of the ink, secure printing free of blurring and enhance the yield of the product, by a method wherein a squeegee in a raised state at the time of turning back an ink is inclined to the side of a scraper. CONSTITUTION:The squeegee 10 and the scraper 30 are moved in connection with the movement of a movable base 1 so that the squeegee 10 is lowered and the scraper 30 is raised at the time of printing, whereas the scraper 30 is lowered and the squeegee is raised at the time of turning back the ink. When the squeegee 10 is raised at the time of turning back the ink, it is inclined to the side of the scraper 30, whereby the ink K which may drip from the squeegee 10 drips into an ink reservoir formed on the front side of the scraper 30 being moved.
