Abstract:
A method of manufacturing a brush head, comprising: locating in a ferrule a basal end portion of a knot of bristles; compressing at least one wedge of resiliently deformable material by an amount such that the at least one wedge remains capable of recovering to its original size and shape; before the at least one wedge has recovered to its original size and shape, inserting the at least one wedge into the basal end portion of the knot of bristles in the ferrule; the at least one wedge, as it recovers compressing the bristles against an inside surface of the ferrule to enhance retention of the bristles by the ferrule; impregnating the basal end portion of the knot of bristles with liquid resin; and thereafter the resin hardens to retain the basal end portion of the knot of bristles in the ferrule.
