Claims
- 1. An apparatus for the surface treatment of an elongated film with an aerosol, comprising:
- a pair of spaced apart facing walls defining an aerosol chamber therebetween, said walls being elongated in a direction travel of the film, said aerosol chamber having an inlet end for receiving film to be surface treated and an opposite outlet end for discharging film after it has been treated;
- an ultrasonic aerosol generator having an aerosol solution chamber for carrying a supply of aerosol solution and an ultrasonic vibrator operatively connected to said aerosol solution chamber for passing ultrasonic waves through said aerosol solution chamber to form an aerosol in said aerosol solution chamber;
- an aerosol duct connected between said aerosol solution chamber and said aerosol chamber adjacent said inlet end of said aerosol chamber for supplying an aerosol into said aerosol chamber from said aerosol solution chamber;
- a suction chamber communicating with said aerosol chamber adjacent said outlet end thereof for drawing aerosol from said aerosol chamber;
- suction means connected to said suction chamber for drawing aerosol from said suction chamber to cause aerosol to move into said aerosol chamber from said aerosol duct;
- an exhaust chamber communicating with said aerosol chamber adjacent said outlet end of said aerosol chamber and downstream of said suction chamber in the direction of movement of the film through said aerosol chamber; and
- an exhaust pipe connected between said suction means and said exhaust chamber for discharging aerosol from said suction means to said exhaust pipe through said exhaust chamber into said aerosol chamber adjacent said outlet thereof;
- at least one of said walls including a secondary air hole for entry of air into said aerosol chamber intermediate said inlet and outlet ends thereof.
- 2. An apparatus according to claim 1, including a tertiary hole in said suction means for admitting air into said suction means for admixing with aerosol being moved by said suction means from said suction chamber to said exhaust chamber.
- 3. An apparatus according to claim 2, wherein said aerosol generator comprises an aerosol solution container defining said aerosol solution chamber and for containing a supply of aerosol solution having an upper level, said container having an opening at a bottom thereof, a vibrator support mounted in said opening, said vibrator support defining a vibrator liquid space, a vibrator transmitter connected to said vibrator support and forming a diaphragm covering said vibrator liquid space and separating said vibrator liquid space from said aerosol solution chamber, a vibrator liquid filling said vibrator liquid space, a vibrator covering said vibrator liquid space on a side of said vibrator liquid space opposite from said transmitter, electrodes connected to said vibrator for applying ultrasonic signals to said vibrator to vibrate said vibrator to form ultrasonic waves which pass through said vibrator liquid and to said transmitter for applying the ultrasonic waves to the aerosol solution in said aerosol solution chamber.
- 4. An apparatus according to claim 3, wherein said vibrator support comprises a flange portion connected to said container and a cylindrical body connected to said flange portion and extending through said opening into said container, said vibrator liquid space being defined in said cylindrical body with said transmitter being connected to one end of said body and said vibrator being connected to an opposite end of said body.
- 5. An apparatus according to claim 4 including an annular fastener engaged over said cylindrical body and engaged against said vibrator transmitter for holding said vibrator transmitter against said cylindrical body.
- 6. An apparatus according to claim 5 wherein said vibrator transmitter is corrugated.
- 7. An apparatus according to claim 5, wherein said container has a conical bottom through which said opening extends, said transmitter and said vibrator lying in parallel planes which extend at an angle to a vertical direction, said container having side walls extending in the vertical direction so that ultrasonic waves pass to the surface of aerosol solution in said aerosol solution chamber at an angle to the vertical direction.
