Definitions
- the cleaning apparatus comprises an ultrasonic horn having a pair of circular opposed shoulders spaced from one y another lengthwise of the horn, defining a circular channel between the shoulders for confining the web, and mechanism for advancing the web through the channel in contact with the shoulders.
- the present invention relates to a novel method of and apparatus for ultrasonically cleaning dirt from a web of flexible material such as photographic film or paper.
- Dirt particles can accumulate from the ambient atmosphere, or can result from slitting and punching operations normally employed during the manufacture of photographic film and paper.
- a web of flexible material such as photographic film or paper is ultrasonically cleaned of small solid particles of dirt in an essentially dry condition by subjecting the web to ultrasonic vibrations in a direction transversely of the web and in the same plane as the web, to shake off the dirt particles.
- This operation desirably is performed by engaging at least one edge, and preferably both edges, of the web with an ultrasonic horn having its major vibration along the longitudinal axis of the horn in a direction normal to theweb.
- FIG. I is a perspective view showing schematically an arrangement of apparatus for continuously ultrasonically dry cleaning moving picture film by engaging its edges with a vibrating ultrasonic horn;
- FIG. 2 is a side elevational view trasonic horn shown in FIG. 1.
- a web 4 of flexible material shown as moving picture film having perforations along one side, is transported from a source over a roll 7 to the ultrasonic horn.
- Film 4 is bent around the horn within channel C and is taken up on a spool 6 driven by a motor 5.
- the transducer 3 is energized to impart back-and-forth vibrations to the flanges l and 2 which engage both edges of the film and impart the vibrations to the film in the film plane, thus shaking off from both top and bottom surfaces any dirt particles present.
- Surface particles have been successfully removed dry which are of the order of three microns, and of ten microns and larger.
- a volatile liquid such as methyl chloroform
- a volatile liquid such as methyl chloroform
- suitable volatile liquids are freons, trichloroethylene, trichloromonofluoromethane, percherooethylene, carbon tetrachloride, dichlorodifluoromethane, dichloromonofluoromethane, monochlorotrifluorethane, and dichlorotetrafluoroethane.
- a method for cleaning dirt particles from a web of flexible material comprising moving said web in a direction lengthwise thereof while contacting at least one edge of said web with a solid ultrasonically vibrating abutment, and ultrasonically vibrating said contacting abutment in a direction transversely of said moving web.
- Apparatus for cleaning dirt particles from a web of flexible material by applying ultrasonic vibrations to said web in a direction transversely thereof comprising, in combination:
- an ultrasonic horn having abutment means extending transversely from a side surface thereof;
- abutment means is a pair of opposed shoulders spaced from one another lengthwise of said horn and defining a channel therebetween for confining said web during movement thereof.
