A brush is formed by laminating 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.
