A film cleaner and method for cleaning motion picture film. The cleaner includes a friction-driven roll, spools of cleaning tape, take-up rolls to draw the tapes from the spools, means for contacting the tapes with the film, and a gearing mechanism connecting the friction-driven roll with the take-up rolls. The film cleaning method includes driving the friction-driven roll with film running through a film delivery and take-up system, contacting the surfaces of the film with the cleaning tapes, and transferring the movement of the friction-driven roll into movement of the take-up rolls to draw the tapes from the spools. Thus, the take-up rolls are driven by the friction-driven roll and essentially clean portions of the tapes contact the film.
Foil used in the manufacture of superconductor material is cleaned using a mechanical abrasive pad that produces longitudinal hills and valleys or elliptical swirls on the surface of both sides of the foil to yield high quality and uniform superconductors.
A system for cleaning a substrate comprising bringing a contact cleaning web into moving synchronous contact with the surface of a member to be cleaned to clean the surface.
A machine optics and paper path cleaner has a relatively stiff backing sheet and a cleaning sheet attached to the backing sheet at a position spaced from the leading edge. The cleaning sheet is folded, flocked or flapped, knitted or engraved with surface variations to aid in the cleaning of paper paths and optics. Wet cleaners are held in absorbent materials and in frangible or openable reservoirs to wet the cleaning material as it is drawn into the machine through the paper path and across the optics. The cleaners are made in single foam sheets of varied thickness and in laminated sheets of stiff backing material and flexible cleaning material.

An apparatus for cleaning film comprising a mounting surface supporting: a first film core for holding film to be cleaned; a first film platter for supporting the first film core; at least one first guide member; at least one first particle transfer roller; at least one first static reducer; a cleaning sub-assembly; at least one pair of buffers; at least one second particle transfer roller; at least one second guide member; a second film core for receiving the film; and a second film platter supporting the second film core. The cleaning sub-assembly is comprised of a pair of drive rollers, a pair of applicators disposed on the drive rollers, a solvent tank to hold a cleaning solution, and a spiral screw within each solvent tank to deliver the cleaning solution to the applicators. The drive rollers and applicators rotate in opposite directions and can also be caused to move laterally.
