A tuft picking device for a brush making machine is provided, comprising
-a filament container for holding a supply of loose filaments in a mutually parallel condition wherein the circumference of at least one of the loose filaments comprises at least one recess,
-a tuft picker having a working surface comprising at least one tuft picking notch with a depth, a width and an opening, wherein the contour of the working surface is adapted to be movable during a working stroke past an open side of the filament container so that the opening of the tuft picking notch passes the loose filaments, wherein two projections reduce the opening of the tuft picking notch versus an inner width, wherein
a top of a first projection is located in the working surface of the tuft picker and a top of a second projection is located off-site the working surface of the tuft picker and inside of the notch, wherein the second projection passes the open side of the filament container last during a working stroke, and wherein a distance from the top of the second projection to the working surface of the tuft picker is in the range of from 0.05mm to 0.5mm and wherein an angle between the working surface of the tuft picker and a line of reflection symmetry crossing the top of the second projection is in the range of from 0° to 45°. |
