Patent ID: 8904604

Claim:
Device for mechanically splitting finite textile fiber bundles, comprising n individual fibers (n≧2) in fiber bundles having less than n individual fibers and/or individual fibers, wherein, in a milling chamber that is closed off from the outside and that has one or more dead spaces of at least 10% of the milling chamber volume and in which one or more rotating striking elements operate in a non-cutting manner and so as to reduce load peaks and at a rotational speed that can be adapted to the material but that is at least 200 r.p.m., the material is adjustably input in different amounts in batches, treated for an adjustable duration, and then discharged again from the milling chamber, wherein the rotating milling unit is equipped with one or more propeller-type striking elements arranged one in back of the other on a drive shaft in the direction of the axis for longitudinal splitting of the textile material into fibrous components, characterized in that the striking elements have sufficient size to mechanically split textile fiber bundles into bundles with fewer fibers or individual fibers and are arranged to elastically rebound or tilt away for gentle treatment of the material and are therefore able to sporadically evade material accumulations that arise during the treatment for a short period of time, and load peaks that are damaging to the material are avoided.
