The present invention is concerned with a process for the filtering out of fibers form an air stream, in which process a stripping blade (3), for the purpose of cleaning, is moved along the surface of a filter (2) installed in a vacuum chamber (10). A controlled linear drive (51) is applied to the said stripper blade (3), by which the stripping blade (3) is made movable for the carrying out of a two phase operational motion along a linear path of travel. The end positions are located at opposite sides outside of the surface of the filter (2) in areas (A, B) wherein the stripping plate (3) is without contact with an opposing surface. During the first phase of travel, the fibrous material is scraped from the surface of the filter (2), while during the second phase of travel of the stripping blade (3) the said fibers are pressed against the filter (2) and the stripping plate (3) essentially moves back over the fiber without taking the said fibrous material with it. The low pressure in the filter chamber (12) is measured, and upon a drip in the measured low pressure to a point lower than a specified low pressure, the stripping blade is activated at least one time to carry out the said operational movement.
A textile filtering apparatus for filtering out fibers from an airstream drawn from a textile machine, said apparatus comprising:
A process for filtering air streams drawn from textile machinery, said process comprising drawing the air stream to be filtered into a low pressure chamber and through a filter disposed in the low pressure chamber, and moving a scraper blade across the filter in a first motion phase from a first position past an edge of the filter to a second position past an opposite edge of the filter wherein the scraper blade scrapes accumulated fiber from the filter, and then from the second position back to the first position in a second motion phase wherein the scraper blade presses against the filter without removing fibers therefrom, and wherein at the first and second positions the scraper blade moves out of contact with the filter.
