(54)	Connection segmented parts brush core

(57) The invention relates to an improved mutual connection (1) of the double walled segmental parts (2,3,4) of a brush core and comprises block shaped thick lips (5,6) with zigzag shaped support ssurfaces (7,8). The joining ribs (14,15; 16,17; 18,19) are as well thickened for a better transference of the force, so that no metal fatigue occurs. The whole of the connection is locked by an inbus screw (12). By the described features a very stable ring connection is obtained for the various double walled segmental parts (2,3,4) with different diameters of a brush core for brush machines being in use for large surfaces, such as e.g. take off and landing ways of airfields.
