Appeal No. 96-3555
Application No. 08/297,021
52. A method of manufacturing a razor blade which includes
the steps of:
stacking a plurality of blades with the edges substantially
at right angles to a selected continuous path;
supporting the blades such that the blades are free to
riffle under fluid pressure directed against the blade edges;
providing a demagnetizing means along said path and moving
the blade stack through said demagnetizing means to ensure
separation of the blades during movement along said path;
thereafter, moving the stack at blades along the continuous
path through a pre-wash station, a wash station, a rinse station
and a final rinse station, each of said stations being separated
by wall structure having an opening formed therein to provide for
movement of the stack of blades therethrough and providing air
under pressure adjacent said wall structure between said wash
station, rinse station and final rinse station to form an air
curtain adjacent each of the openings;
applying a liquid to the stack of blades at each of the pre-
wash, wash, rinse and final rinse stations, the application being
directed at an angle and pressure to cause riffling of the blades
within the stack;
providing non-contaminated water for said application at the
final rinse station;
circulating the applied water from the final rinse station
to the rinse station for said application at the rinse station;
and
circulating the applied water from the rinse station to the
pre-wash station for said application at the pre-wash station.
