Claims4
A process for cleaning interior walls of a ring-like strap of the type used to hold and release magnetic tape for fluidic feeding in tape-reading apparatus, the strap comprising an annular conduit between interior and exterior walls of said strap, said conduit terminating in spaced apertures in said interior wall thereof, said process comprising the steps of
- (a) supplying the air through said exterior wall under pressure into said annular conduit to maintain positive air-streams coming out of said apertures in said interior wall and, thereby, preventing dirt in interior walls from being forced into said apertures while
- (b) carrying out a relative rotation between (1) a suction-cleaning means mounted in biased contact with said interior wall and (2) the interior wall of said strap.
