  • Patent number: 11149176
    Abstract: The invention relates to a method for producing an alumina based abrasive particle (1), comprising at least the following steps: forming a sol as a solution or dispersion of alumina particles, gelling the sol by adding gelling agents, forming shaped bodies from the gel using an additive procedure, drying and firing the shaped bodies while retaining the previously achieved geometry of the abrasive particles. Hereby, it is provided that an optically binding binder is added to the sol and/or the gel, the gel is applied additively layer by layer and the binder is set using electromagnetic radiation so as to form the shaped bodies. The produced abrasive particle may be formed, in particular, by six intersecting or overlapping triangular volume regions.
    Type: Grant

  • Patent number: 10843309
    Abstract: Method for manufacturing a non-woven abrasive article, and non-woven fibers are made of a certain starting material and are subjected to method steps of forming a non-woven web, then consolidating the non-woven web. In order to improve the homogeneity, as well as the reproducibility of the non-woven abrasive article manufactured, the non-woven fibers, prior to the method step of forming a non-woven web and/or prior to the method step of consolidating the non-woven web, are coated with abrasive grains in such a way that the abrasive grains adhere to the certain starting material.
