Brush for application of products to keratin materials, especially for application of mascara, having at least some of the bristles curved inwards relative to the core

摘要

In a brush for application of products to keratin materials, consisting of a core and bristles supported by the core (but not produced by injection molding together with the core), at least some of the bristles are curved inwards relative to the core. Independent claims are included for: (a) a method for production of the brush, involving curving the bristles by contact with a heated surface, preferably in motion relative to the brush; and (b) a machine for carrying out the method, comprising a support for at least one brush; a treatment device comprising a surface for contacting the bristles and a heater for the surface; and a system for displacing the support relative to the treatment device so that the orientation of the bristles is modified by contact with the surface.
