A sweeper brush section comprising a deformed metal channel with a plurality of outwardly-opening cups or sockets at regularly spaced intervals in which are positioned the inner U-shaped ends of tufts or bunches of wire bristles mounted in non-metallic sleeves. These sleeves are pivoted in the respective cups about transverse axis for limited movement to prevent breakage of the bristle wires, especially at the time of the initial impact of the wires with the surface being swept.
