Abstract
A device for rounding the ends of the fibres of brushes (1), in particular fibres which are made of synthetic material, contains a first support (5) which can be moved in a direction in relation to a brush (1); a second support (4) which is mounted, rotatable around an axis (10) which is at right angles to this direction, on the first support (5); a first drive assembly (15) to rotate this second support (4); a grinding surface (3) which is mounted in a moveable manner on the second support (4) and against which the fibres are provided; and a second drive arrangement (12) to move this grinding surface (3). The grinding surface (3) is at least part of the jacket of a cylinder (2) whose axis (11) is directed crosswise to the axis (10) around which the second support (4) rotates in relation to the first support (5).
