The invention relates to a method for producing bristle products. Individual bristles or groups of bristles consisting of synthetic material are fixed to a carrier in a predetermined arrangement, forming the desired bristle area. At least one part of the bristles in the predetermined arrangement or in the fixed bristle area is structured by means of laser beams in a contactless and preferably regular manner. Furthermore, the bristles are shortened in a contactless manner at the free ends thereof by means of laser beams. In this way, structures are produced in a reproducible form on the outer and upper side of the bristle area, said structures assisting the cleaning action.
L'invention concerne un procédé pour produire des articles de brosserie. Selon ce procédé, des poils en matière synthétique, individuels ou regroupés, sont fixés sur un support selon un agencement prédéfini, de manière à former la garniture de poils souhaitée. Au moins une partie des poils de l'agencement prédéfini ou de la garniture fixée est structurée sans contact au moyen de rayons laser et de préférence de manière régulière. Au niveau de leurs extrémités libres, les poils sont raccourcis sans contact au moyen des rayons laser. Ce procédé permet de créer, de manière reproductible, des structures facilitant l'action nettoyante de la garniture de poils à l'extérieur et au sommet de cette dernière.
