Abstract

1309270 Band brakes MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 1 April 1970 [7 Oct 1969] 15497/70 Heading F2E A band brake for use with a reel bed 101 of a tape recorder which is independent of varying coefficients of friction and having a band for braking a drum 115 associated with the reel bed 102 may comprise a single spring for applying the band to the drum connected between two ends of a lever and a fixed point of the recorder or may comprise two levers 110, 107 engaged by springs 109, 105 spring 105 being of greater strength than 109 and adapted to engage stops 111, or 108 to nullify the force of the spring associated therewith according to the rotational direction of the reel bed. With the reel bed rotating in a direction b, lever 110 engages a stop 111 to nullify the force of spring 109, braking being effected purely by spring 105. Rotating in the reverse direction spring 105 is nullified as lever 107 engages stop 108 and spring 109 is solely responsible for braking.
