Abstract: A roll to roll fabrication apparatus includes an injection plate for injecting a chemical treatment liquid on a film transferred from a supplying roll to a collecting roll; and liquid blocking rolls disposed between the supplying roll and the collecting roll, and configured to prevent the chemical treatment liquid injected from the injection plate from being introduced to another process region.
Abstract: A printing press includes an anilox printing unit having a screen roller and a feed blade as components, in which ink accumulates on an outer side of the feed blade during printing. A method for operating the anilox printing unit includes removing the accumulated ink from the feed blade by moving one of the two components relative to the other of the two components in a first direction in a first step, causing the accumulated ink to be flattened by the feed blade and to be spread onto the screen roller. The component that was moved in the first direction in the first step may be moved in an opposite, second direction in a second step, causing the accumulated ink to be scraped off the screen roller by the feed blade.
