Abstract
A method of attaching a plurality of bristles each having a maximum strain that is less than 8% to a brush to form two spaced apart tufts. The method includes arranging the bristles adjacent and substantially parallel to one another to form a bristle grouping. The bristle grouping is divided longitudinally into an anchor portion flanked on both sides by a tuft portion. The anchor portion is bent in a manner that subjects the bent portion to less than about 8% strain. The bent anchor portion is inserted into and affixed to the bottom of a slot or aperture having an inside surface configured to receive the bent anchor portion of the bristle grouping and guide the tuft portions outwardly from the slot. The portion of the slot above the anchor portion and between the tuft portions may be filled with a material to separate the tuft portions.
