ABSTRACT:
A side brush, which is adapted to be mounted on the body of a sweeping machine, for use as a brush rotatable about a rotation axis, and which includes a base and a plurality of individual bristle segments detachably mountable thereto, having bristles included therein integrated for a solid unit with a frame member joining the same. The base includes a substantially planar disc assembly which is provided integrally with a coupling system for coupling the bristle segments therewith on a snap fit principle. The coupling system includes elongated channels disposed in the base in a substantially radial direction and extending through the base, opening all the way to the edge thereof, which enable coupling the bristle segments immovably to the engagement with the body of a sweeping machine by means of the base with fasteners interconnecting the same.
