Abstract
Abstract Tufted style brushes are herein disclosed which overcome many of the disadvantages associated with the use of stapleset brushes. The brushes of the instant invention include a plate of rigid or semi-rigid material, such as sheet metal or reinforced synthetic material, having a plurality of holes pierced therethrough, said plate being relatively smooth on the obverse side, and having flanged or raised areas circumferentially surrounding each hole on the reverse side. Tufts are secured in the holes of the plate by means of a ring which presses against the flanged area to create a positive locking effect. Finally, the structure can be provided with a securely fastened backing element.
