ABSTRACT:
A brush including a laminate having a handle end portion adapted for manual engagement, and an opposite head end portion; and a plurality of rows of bristles having end portions adhered between adjacent plies in the head end portion of the laminate and projecting outwardly. The brush is formed from pieces of oriented polymeric film, portions of which are adhered to individual plies to be incorporated in the laminate and have portions projecting from the plies separated into bristles before the plies are laminated to form the brush. Lamination is done by driving moisture out of pasteboard layers coated with dried water activatable adhesive by exposure to radio frequency energy which activates the adhesive to form the laminate.
