The invention relates to a method for manufacturing of a brush ring, whereby the brush ring is intended to be used particularly with several corresponding brush rings as a brush, that rotates around a longitudinal axis, in a brushing machine. The brush ring consists of a brush part (1) and a ring shaped frame part (2), that connects the radially directed (r) brushes (1a) forming the brush part (1), which parts (1, 2) are formed as a uniform entirety preferably from plastic based material, and in which there has been arranged at least holding means (3) to prevent the brush ring from twisting, when the same has been assembled in place to the brush frame of the brushing machine. The brush ring is being manufactured from an essentially elongated brush preform (1'), in which the brushes (1a) are connected to each other by melting (1's), wherein on the melting (1's) existing at the top edge of the brush preform (1'), that moves along in an essentially upright position, plastic paste (2'), is being led, that is in an essentially solid state, to work the brush ring to its final shape by means of a press mold assembly (X) by forming the frame part (2) and preferably the holding means (3) from the said plastic paste (2'). The plastic paste (2') is being led bent in a ready finished shape, such as through a U-shaped extrusion groove (U) or correspondingly, on top of the melting edge (1's) of the brush preform (1'), that is as an advantageous embodiment being preheated in the same connection. The invention relates to an apparatus, also, that operates according to the method.
