Abstract
A brush making machine with a mold for injection molding of brush bodies is disclosed. The mold comprises a stationary mold part, a movable mold part and a pair of insert parts fitting into a recess of the movable mold part. The insert parts have tuft insertion holes therein. While one of the complementary mold parts fills the recess of the movable mold part and brush bodies are injection molded with tufts of bristles embedded in the molding material, the other insert part is in a tuft loading station for introducing tufts of bristles into the tuft insertion holes. The tuft feeder comprises movable tuft carriers which carry sets of tufts from the bristle containers to the mold. A robot is provided for moving the carriers between the mold and the bristle containers.
