BRUSH HEAD AND METHOD AND TOOL FOR PRODUCING SAME

摘要

A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements, such as bristle tufts may be fused by heat and may be placed in a mold cavity to be over-molded.

主权项

1. A method for producing a brush head in which at least two different cleaning elements selected from the group consisting of different types of cleaning elements, distinctive cleaning elements of the same type and a combination thereof, are embedded at one of their ends at least partially in a bristle carrier, wherein the ends are fused by infrared radiation before embedding, wherein different amounts of infrared radiation are supplied to each of the at least two different cleaning elements, wherein the different amounts of infrared radiation are supplied by a plurality of reflectors that are spatially adjustable relative to one another, and wherein the different amounts of infrared radiation are controlled by a frequency or intensity of the infrared radiation.
