Abstract
An apparatus for processing film by scrubbing having a rotatable scrubbing roller, an acurately shaped scrubbing plate with its inner surface adjacent to and in scrubbing relationship with the scrubbing roller and means for guiding the film to be processed in linear movement between the roller and the plate. A method for processing film by scrubbing which comprises the steps of guiding the film in an arcuate path in scrubbing relationship with the peripheral surface of a scrubbing roller and rotating the scrubbing roller.
Claims15
An apparatus for scrubbing the surface of a film comprising:
- a reservoir for containing a scrubbing solution;
- an elongated rotatable scrubbing roller;
- an elongated arcuately shaped scrubbing plate adapted for at least partial submersion in said scrubbing solution, the inner surface of said plate being adjacent to and in scrubbing relationship with said scrubbing roller to thereby define a scrubbing station;
- means for guiding the film in linear movement between said scrubbing roller and said plate;
- and
- means for circulating said scrubbing solution between said reservoir and said scrubbing station comprising a plurality of holes disposed in said scrubbing plate such that said holes are adapted for at least partial submersion in said scrubbing solution.
An apparatus for scrubbing the surface of a film comprising:
- a reservoir for containing a scrubbing solution;
- an elongated rotatable scrubbing roller;
- an elongated arcuately shaped scrubbing plate adapted for at least partial submersion in said scrubbing solution, the inner surface of said plate being adjacent to and in scrubbing relationship with said scrubbing roller to thereby define a scrubbing station;
- means for causing circulation of said scrubbing solution between said reservoir and said scrubbing station;
- and
- means for guiding said film toward said scrubbing roller and plate and away from said scrubbing roller and plate, said means including a rotatable guide roller mounted above said scrubbing roller and first and second idler rollers associated with opposing surfaces of said guide roller for guiding said film to and from said scrubbing roller and plate.
