Abstract

In a mascara brush comprising a plurality of bristles held between two twisted wire segments, wherein the bristles have varying lengths created by trimming, provision is made for the brush to incorporate a first outer face of a predefined geometry created in a first trimming process after twisting, wherein this outer face is formed by the tips of a first number of longer bristles, wherein a portion of the bristles is trimmed by a second trimming process, so that a plurality of bristles of a shorter length is created, the tips of which form a second envelope of a predefined geometry, wherein the tips of the shorter bristles each lie on an orthogonal line relative to these twisted wire segments extending at a distance to the same.
