Abstract

To improve the brush-making field, a tuft-picking device (4) is provided, which includes the tuft picker (8) that is movable in relation to the material box (2) of the brush-making machine (1) and, on its front side (11), which in the operating position faces the bristle supply (3) held in the material box (2), includes at least one tuft-picking notch (12). The tuft-picking notch (12) has two opposing knife edges (14, 15), which delimit the notch opening (13) of the tuft-picking notch (12) and are oriented transverse to the direction of movement of the tuft picker (8). Another part of the tuft-picking device (4) is the counter piece (9), which is provided with the separating edge (17) facing the tuft picker (8). In order to allow bristle filaments (16) to be removed from the bristle supply (4) as gently as possible, at least one of the two knife edges (14, 15) and/or the separating edge (17) is rounded.
