Apparatus for producing patterns on advancing strips

摘要

Apparatus for producing pattern on advancing strips such as strips of textile and similar materials in which a roller rotates in a trough picking up a liquid such as a dye used for producing the pattern and carrying the liquid to a scraper blade slanted toward the strip of material with the scraper blade scraping off the liquid adhering to the roller which is then permitted to run down onto a strip moving therebelow. In accordance with the present invention, a plurality of movable channels are provided at the bottom end of the scraper plate, the channels being movable between one position in which the liquid is permitted to flow onto the moving strip and another position in which the liquid is directed to a catch pan from which it can be returned to the trough with means provided to oscillate the channels so as to produce a desired pattern on the strip.
