Abstract
A tuft-picking device for a brush-making machine includes a container for holding loose filaments with circumferences having at least one recess; and a tuft picker having a working surface having a notch. The notch has a depth, a width, and an opening. A contour of the working surface is movable during a working stroke past an open side of the container so that the opening passes the loose filaments. First and second projections reduce the opening versus an inner width. The first projection's top is located in the working surface of the tuft picker and the second projection's top is located off-site the working surface and inside the notch. The second projection passes the open side of the filament container last during a working stroke. A distance from the top of the second projection to the working surface is from 0.05 mm to 0.5 mm, and an angle between the working surface and a line of reflection symmetry crossing the top of the second projection is from 0° to 45°.
