Bristles, method and device for production thereof and brushes

A bristle for mounting in or to a bristle support, in particular for a cleaning brush, a toothbrush, or an application brush, the bristle comprising:

• a lower root region, said root region for mounting in or to the bristle a support or for forming a part of the bristle support;
• a lower shaft base section bordering said root region;
• a shaft section disposed adjacent to and above said lower shaft base section, said lower shaft base section and said shaft section forming a shaft region;
• a lower active flexing section bordering above said shaft region;
• a tip section disposed above and adjacent to said lower active flexing section and defining a free end of the bristle,
• said lower active flexing section and said tip section constituting a flexing region, said flexing region and said shaft region constituting a free length of the bristle lying outside of the bristle support and being disposed above said root region,
• wherein the bristle has a continuous, depression free jacket in said shaft base section and in said shaft section, and
• at least portions of a jacket in said flexing region have a profiling defining elevations and/or depressions disposed within a peripheral surface of the bristle;
• wherein said profiling comprise at least one groove which extends about the bristle, and
• wherein said shaft region comprises 15% to 85% of said free length of the bristle;
• and
• wherein said profiling has several longitudinal grooves disposed next to each other about a circumferential direction of the bristle.
