Abstract
In a method for producing brushware, individual bristles of plastic material or bristles combined into groups in a predetermined arrangement are mounted onto a support, thereby forming the desired bristle stock, and at least one part of the bristles in the predetermined arrangement or on the mounted bristle stock is provided with a preferably regular structure in a contact-free fashion using laser radiation. The invention also proposes contact-free cutting of the free ends of the bristles through laser radiation thereby producing, in a reproducible fashion, structures on the outside and on top of the bristle stock to support the cleaning action.
Claims19
A method for producing brushware, the method comprising the steps of:
- a) defining a predetermined arrangement of individual bristles or bristles combined into groups;
- b) mounting said predetermined arrangement onto a support to form a mounted bristle stock;
- c) irradiating laser radiation from an orientation substantially parallel to a longitudinal extent of said bristles to shorten and round free ends of at least some of said bristles;
- and
- d) irradiating laser radiation from an orientation substantially transverse to said longitudinal extent of said bristles to structurally modify outer sides of said bristles in regions thereof sufficiently removed from said free ends that the structural properties of said free ends remain substantially constant.
