Abstract (en)
[origin: WO2019233839A1] The invention relates to a device (1, 1A) for matting a surface (12), having a nozzle (3, 3A), which has a blasting chamber (4, 4A) for blasting a workpiece (10, 10A) with an abrasive blasting material, wherein the blasting chamber (4, 4A) has, on at least one of the sides of same, at least one flat interaction opening (5.2), which is provided for being interlockingly placed onto at least one surface (12) to be matted, the blasting chamber (4, 4A) being closed as a result. According to the invention, the workpiece (10, 10A) and the nozzle (3, 3A) remain rigid with respect to one another during the blasting process, wherein a direction of a blasting agent blast (9) of abrasive material within the blasting chamber (4, 4A) can be oriented approximately parallel or at an angle of less than 30° to the interaction opening (5.2) and to the surface (12) to be matted.
