Method for quality inspection of bristles and use of said bristles

摘要

For the quality control or inspection of the bristles intended to be used on bristles, especially the bristles which are rounded to the spherical tip, the juxtaposed ends of the hairs are recorded as image recognition or identification devices, and the degree of rounding of the bristles It is confirmed by image evaluation. To obtain fully reproducible results, the hairs with jackets are juxtaposed in parallel positions and their ends are oriented in a flat envelope. Before or after juxtaposition, the ends are subjected to surface structuring for contrast to the hair jacket. The ends of the fur are then recorded as an image recognition device. Particularly, quality control involves confirmation of the molding quality of the ends, and may also include the total surface area of the hair field and the surface ratio to the number of hair per surface unit. Dyed ends for this method may also be used to indicate the degree of wear of the fur on the finished brush product.
