A tuft picker for a brush-making machine for automated production of brushes, toothbrushes adapted to remove filaments from a filament container. The tuft picker includes two cover tools spaced by a picking part. The picking part has at least one picker eye for taking up a predefined number of loose filaments from the filament container. This picker eye has an opening that can be opened and closed by moving the cover tools from a first position to a second position during one working stroke.

An automatic handle assembly system for a paint brush, including a feeding device, a conveying device, a handle pushing device, a pneumatic system, and a control system. The feeding device is used for transporting a glue-filled paint brush head to an entrance of the conveying device. The conveying device is used for realizing transportation, pressing and precise positioning of the paint brush head. The handle pushing device is used for pushing a paint brush handle to precisely insert into the paint brush head. The feeding device, the conveying device, and the handle pushing device are all connected to the pneumatic system and the control system.

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.

An apparatus for manufacturing an individual brush unit constituting a rotary brush by being stacked in multiple layers, includes an anvil having an insertion hole through which a filament group passes, a filament feeding unit which feeds the filament group from a feeder including a ring cutter on a tip and holds the filament group while a predetermined amount of the filament group protrudes outward from the insertion hole of the anvil, and an ultrasonic welder including a horn having a horn tip portion which pushes and radially expands a protruding tip of the filament group and welds a central part of the expanded filament group, to form the individual brush unit. A core of the welded central part is sandwiched between the ring cutter and the horn tip portion and is cut out, to simultaneously form a shaft hole and separate the individual brush unit from the filament group.

An improved clamping apparatus (8) for use in brush production is provided. The clamping apparatus (8) has at least one plug-in receptacle (13) for a fastening stud (12) of a bristle carrier (7) which is to be clamped, and at least one clamping element (14) assigned to the plug-in receptacle (13). This clamping element (14) can be advanced transversely with respect to a longitudinal axis of the plug-in receptacle (13) from a starting position into a clamping position in which it secures the bristle carrier (7) via its fastening stud (12) on the clamping apparatus (8).
