Embodiment Construction

[0027] exist figure 1 The brush manufacturing machine 1 for round brushes 2 shown in a very simplified manner has two wire twisting devices 3a, 3b, which are mounted rotatably (arrow PF1) on Between an insertion position 4 and a processing position 5 .

[0028] On the insertion position 4, the metal wire 6 and the bristle wire 7 ( figure 2 ) into the wire twisting device 3a located there ( figure 1 ). The two wire twisting devices 3a, 3b each have two grippers 8 spaced apart from each other, by means of which the wires are clamped. The grippers 8 are respectively driven by a servomotor not shown, wherein the two grippers 8 of the wire twisting devices 3a, 3b are positioned according to the arrows Pf2 and Pf3 figure 2 in the opposite rotational motion.

[0029] The servomotor is initially operated at a low rotational speed in order to prevent individual bristle filaments 7 from falling out. As soon as the bristle filaments 7 are securely clamped between the wires 6 , th...

Abstract

The machine (1) has two wire twisting devices (3a, 3b) positioned between an inserting place (4) and a processing and / or ejection place (5). The wire twisting devices are driven during the positioning movement between the inserting place and the processing and / or ejection place for twisting. The wire twisting devices are arranged at a rotatably supported drum and exhibit two gripping arms (8) for holding wires (6), where the arms are arranged at a distance from each other. A cooling device is provided for the wire twisting devices.

Description

technical field [0001] The invention relates to a brush maker for round brushes with bristles screwed in between wires, said brush maker comprising a bristle feeding device and a wire twisting device. Background technique [0002] In the manufacture of round brushes such as bottle brushes, toothbrushes or mascara brushes, the bristle filaments are positioned between two wires or between the two wire arms of a U-shaped bent wire and clamped to them by rotating the wire connected. In order to avoid slipping of the bristle filaments during rotation, the screw-in speed and thus the maximum possible processing speed are limited. [0003] From EP 1 917 886 A1 a method and a device for producing round brushes are known, in which the processing takes place on a plurality of downstream workstations. In particular, the bristle filaments are first screwed in at a reduced rotational speed in order to fix the bristle filaments between the wires. Next, the round brush is transferred to...
