Support plate and brush, in particular toothbrush with support plate

Abstract

A method and a device (1), a support plate (17) and a brush (60) loaded with such a support plate (17) for the manufacture of a bristle field of a brush enable the manufacture of a bristle field of a brush to be simplified in that, The bristle bundle (5) transported to the bundle holding plate (9) by means of the air flow or air flow through the conveying device (6) is destaticized when it is conveyed through the conveying device (6), making it easier for the bristle bundle to pass through the conveying device (6) ) transportation and thus reduce the cost of fixing the bristle bundles (5) in the support plate (17) without anchors, because the support plate (17) has a material protrusion (54) on the rear side, which is melted and then removed Pressed into the bundle fixing plane, so that the bristle bundles (5, 5a) inserted in the holes (24) of the carrier plate (17) are form-locked and / or non-positively connected to the carrier plate (17) in a simple manner ( image 3).

Description

technical field [0001] The invention relates to a method for producing a bristle field of a brush, in particular a toothbrush, wherein the bristle filaments are removed from a magazine containing a stock of bristle filaments and assembled into tufts of bristles, after which the bristles are separated by means of an air or air flow The bundle is guided through a transport device comprising a bundle containing device and a hollow conduit connected thereto and then fed into the bore of the bundle holding plate. [0002] The invention relates to a carrier plate comprising a plurality of holes extending through the carrier plate, into which holes bristle tufts of bristle filaments can be inserted and fastened to the carrier plate without anchors. [0003] The invention also relates to a brush, in particular a toothbrush, comprising a handle and a brush head having a carrier plate receptacle and a carrier plate fastened therein, loaded with bristle bundles.

AI Technical Summary

Problems solved by technology

[0007] It may happen, for example, that some bristle filaments or even entire bristle bundles get stuck in the transport device and do not reach their destination

Especially when the bristle filaments are extremely fine, it is very difficult to reliably supply the bristle filaments via the transport unit

[0008] Also in the support plate as disclosed in the prior art and defined at the beginning and in the brushes equipped with such a support plate, in particular the absence of anchors for the bristle bundles supplied to the support plate according to the method mentioned at the beginning and on the device mentioned at the beginning The fixation of the
