Abstract
A yarn braking device, in particular a double plate brake for textile yarns running from bobbin creels, with two pairs of brake plates through which the yarn passes and whose top and bottom plates are to be pressed together adjustably in order to tension the yarn passing through, with a two-armed plate lever disposed beneath the pair of brake plates and able from that location to influence pressure loads each of the pairs of plates by means of a respective one of the lever arms, and with a pressure adjusting device acting on the plate lever. So that both pairs of brake plates can be used at pressing forces as low as zero for the finest yarns and at maximal pressing forces for coarse yarns without the need to exchange the pressure adjusting device or its spring, it is proposed that the two-armed plate lever is able to lift the bottom plates of the pairs of brake plates out of an operating position in which practically no pressure is exerted on the top plates, and that the pressure adjusting device acts on the plate lever by means of a rocking lever (,) comprising attack sites, located at different distances from the plate lever, of an element generating a setting force.
