And if the tuft is too large, one or more bristles may not be implanted in the form bar, but curled sideways, preventing the tuft from being fully inserted into the form bar, which will then Interference with the injection molding process
[0008] If it is necessary to position the tufts so that the resulting toothbrush tufts have different lengths and / or different extension angles, this will pre-cut The drawbacks inherent in the method by which the out tufts are conveyed from a hopper to a die rod are usually exacerbated by

Embodiment Construction

[0050] The preferred implementation of the present invention generally includes the following steps, which are discussed briefly here and described in more detail below. The following process is suitable for producing toothbrushes 10 with tufts 12, 14, 16 of different lengths, wherein the extension angles of those tufts are also different from each other, for example for the production of figure 1 The toothbrush shown. In this document, the arrangement of the clusters will be referred to as the cluster geometry. The tufts of bristles are held on a mold rod 28 (see Figure 12 and 13 Middle), which has the ideal tuft geometry and is used as part of an injection molded cavity for forming a toothbrush handle 18 around the tuft.

[0051] see in general figure 2 and Figure 4 , the filament bundles composed of bristle material are arranged in the form of a plurality of filament bundles 22, and the diameter and number of filaments of each filament bundle 22 are corresponding to...

Abstract

The present invention provides methods and devices for tufting oral brushes. The methods include inserting free ends of continuous strands of filaments into blind openings in a moldbar, at least some of the blind openings having different depths and / or extending at different angles.

Description

[0001] The present invention is a divisional application of the Chinese invention patent application titled "tufted toothbrush" and application number 02811789.1. technical field [0002] The present invention relates to a method and machine for making a cluster toothbrush. Background technique [0003] Conventional toothbrushes generally include tufts of bristles mounted on the head of a toothbrush handle. Until recently, the bristles were generally mounted vertically to the upper surface of the toothbrush head, and the individual tufts were also the same length. Methods and apparatus for installing bristles in this orientation are also known. [0004] Recently, the oral care industry has recognized the advantages of toothbrushes having bristle tufts of different lengths and / or tufts having different angles of extension relative to the toothbrush head. figure 1 shows a toothbrush whose tufts extend at different angles. [0005] A method of manufacturing a toothbrush comp...
