Brush made from bristle bundles which are folded centrally

摘要

The brush is built up from bundles of bristles which are folded over along their centre so that their ends lie next to one another. The folded bundles are mounted in holes in the brush handle in which they are secured with small anchor plates (4). The holes in the brush handle may be oval. They may be shaped so that they have flat side faces in between which the anchor plates have a good fit.
