Tape wiping brush, particularly for magnetic tape cassettes and the like

Claim 2

A tape wiping brush, particularly for magnetic tape cassettes and the like, comprising a flexible reed extending over a substantially flat length and defining, at opposed ends, a mounting zone for attachment to a cassette and a tape pressure zone having a contact liner attached thereto, characterized in that said contact liner has a flap extending along a tape contacting edge at the opposite end to said mounting zone, said flexible reed being formed, at said contact edge, with a fold line extending in a substantially orthogonal direction to the direction of movement of said tape to define a portion sloping away from said tape, said flap being secured on said sloping portion of said reed.

Claim 3

A tape wiping brush according to claim 1, said mounting portion of said reed being adapted for coupling to a seat on said magnetic tape cassette, comprising at least one tab extending over a substantially middle section of said mounting portion and being inclined on the plane containing said flexible reed to diverge away from said plane toward said pressure zone on the same side as said contact liner.

Claim 4

A tape wiping brush according to claim 1, characterized in that said sloping portion diverges away from said tape with respect to the plane containing said flexible reed by an angle in the 1° to 89° range.

Claim 5

A tape wiping brush according to claim 1, characterized in that said sloping portion diverges away from said tape with respect to the plane containing said flexible reed by an angle in the 25° to 35° range.

Claim 6

A tape wiping brush according to claim 1, comprising, formed in said flexible reed between said mounting zone and said tape pressure zone, windows effective to improve the flexing properties of said reed.

Claim 7

A package of tape wiping brushes of the type according to claim 1, characterized in that a plurality of such brushes are arranged side-by-side and similarly oriented, adjacent brushes being mutually connected by crosspieces to form a continuous wiping brush web.

Claim 8

A tape wiping device, particularly for magnetic tape cassettes and the like, comprising a lamina having one end portion thereof defining a mounting zone for attachment to a cassette, remote from said mounting zone another end portion of said lamina defining a tape facing surface on one side of said lamina and a back surface on the opposite side of said lamina and a wiping liner covering said tape facing surface and leaving free said back surface, said wiping liner having a tape contacting surface portion and a further surface portion departing from said tape contacting surface portion in a direction away from said mounting zone, said further surface portion forming an angle with respect to said tape contacting surface portion at least in an operative condition of said wiping device.

Claim 9

A tape wiping device, particularly for magnetic tape cassettes and the like, comprising a lamina having one end portion thereof defining a mounting zone for attachment to a cassette, remote from said mounting zone another end portion of said lamina defining a tape facing surface on one side of said lamina and a back surface on the opposite side of said lamina and a wiping liner covering said tape facing surface and leaving free said back surface, said wiping liner having a tape contacting surface portion and a further surface portion departing from said tape contacting surface portion in a direction away from said mounting zone, said further surface portion forming an angle with respect to said tape contacting surface portion at least in an operative condition of said wiping device.

Claim 10

A device according to claim 7, wherein said further surface portion of said wiping liner defines a flap formation of said wiping liner extending beyond said another end portion of said lamina.
