Embodiment Construction

[0067] according to figure 1 , a device for the manufacture of round brushes 37 , designated as a whole by 1, has a wire spool 2 with a wire 3 which is unwound from the wire spool 2 and brought via two deflection rollers 4 to In the area of ​​the steering gear 5. The wire 3 is first unwound so far that the free end of the wire 3 is positioned as a wire section 6 a past the deflection device 5 . A wire section 6 a , 6 b of the unwound wire 3 is therefore located above and below the deflection device 5 . The wire section 6a forming the free end of the wire 3 is approximately as long or slightly longer than the round brush 37 to be produced in order to compensate for the shortening in the main longitudinal direction during screwing. When the free wire section 6a is longer than the available space, the wire 3 can be guided through a deflection unit 7 which is formed as a hollow guide in the shape of a circular sector in the figure and bent thereby, so that the wire 3 can Unwind...

Abstract

The present invention relates to an apparatus and method for producing round brushes. The apparatus for producing round brushes, which have bristles twisted in between two portions of a folded wire. The apparatus has a bristle feeding device and a rotary gripper for twisting two portions of wire with bristles located therebetween, a deflecting device with two deflecting rollers spaced apart in the longitudinal direction of the wire. The rotary gripper is linearly displaceable transversely in relation to the longitudinal direction of the wire, for gripping the folded region of the wire that is formed by force being applied by an application element that is adjustable between the deflecting rollers transversely in relation to the longitudinal direction of the wire. A bristle feeding device, for feeding bristles to the bent-around portions of wire, is provided in the region of the deflecting rollers. In the region of the unfolded portions of wire there is provided a device for slowing the advancement of the wire.

Description

technical field [0001] The invention relates to a device and a method for producing a round brush with bristles screwed between two wire sections of a folded wire, wherein the device has a bristle delivery device and a Rotary clamp for twisting two wire sections with bristles located in between. Background technique [0002] Such devices are known in various embodiments together with the associated production methods. For example, a method and an apparatus are known from EP 1 917 886 B1, wherein the bristles are conveyed between two wire segments of a previously folded wire, so that the wire segments are thus The rotation is such that the bristles are held between the wire sections and the thus prefabricated brush is rotated to the desired degree of winding at the second winding station. But this is very expensive due to the multiple processing stations. Furthermore, such devices are only suitable for smaller brushes, such as mascara brushes, since in larger brushes with ...
