Definitions
- the invention relates to a method and a device for processing screwed-in brushes, in particular for processing interdental brushes.
- Screwed brushes are previously known in various embodiments from the prior art. They are inter alia as so-called ⁇ interdental brushes are used and are used to clean between teeth. When using these brushes, bristle ends of bristle filaments of the brushes usually come into direct contact not only with the tooth flanks to be cleaned, but also with the comparatively sensitive gums of the user. Contact with the bristles can endanger the sensitive gums.
- the object of the invention is therefore to provide a method and a device of the type mentioned, which reduce or even avoid the risk of injury when using such twisted brushes on the gums of a user.
- the sharp edges or burrs described above can occur at the ends of the bristles when cutting or shortening the individual bristle filaments to the correct length during the production of the brushes.
- the brush can be introduced at least with their bristle trim first in the grinding sleeve before the free bristles ⁇ are ground off the brush.
- the insertion of the brush in the grinding sleeve can be done by an insertion movement of the brush relative to the grinding sleeve, by a relative to the brush from ⁇ guided AufSteckterrorism the grinding sleeve or by a combined movement of the brush and grinding sleeve.
- the brush can be centered in the machining position within the grinding sleeve. This promotes equal ⁇ timely and uniform processing of the free bristle ends of the bristle
- the abrading of the free bristle ends of the brush verwen- finished grinding sleeve can on its inside, which faces the brush and its bristles when using the grinding sleeve, have a rough surface or be coated with a Schleifmit ⁇ tel. It can be advantageous if the grinding sleeve is moved relative to the brush in order to generate a grinding movement. Mög ⁇ After all, it is also to produce the brush to loading relative to the sanding sleeve for the aforementioned grinding motion for abrading the bristle ends.
