A method of processing toothbrushes includes supplying a plurality of toothbrushes with tufts of bristles attached to heads of the toothbrushes. Similar portions of each of the toothbrushes differ in color from each other. A color of the portion of each of the toothbrushes is determined. The toothbrushes are reorganized according to the determined color.

Method and apparatus for processing toothbrushes

Methods and apparatus for automated brush assembly are disclosed. A method of end-rounding bristle ends with an abrasive surface in random orbital motion relative to bristle tufts held in a movable gripper is described. A novel tuft carrier adapted to hold a plurality of bristle tufts in an arrangement suitable for direct mechanical insertion into the tuft chambers of a brush mold is also described. The tuft carrier has a plurality of tuft insertion cavities and a plurality of movable clamps, each clamp adapted to at least partially occlude one of the cavities when closed. Individual bristle tufts, having a fused end and a rounded or non-rounded bristle end, are transferred from a movable gripper to the tuft carrier by direct mechanical insertion. In addition, an apparatus for direct mechanical insertion of bristle tufts from a tuft carrier into the tuft chambers of a brush mold is described.
