Brush manufacturing machine

Brush manufacturing machine (1) comprising:

• a first injection-molding machine (18) for region-by-region injection molding of material around bristle bundles (7) held in cartridges (9) and for forming a bristle carrier (19) connecting the bristle bundles (7), and a second injection-molding machine (24) in which the bristle carrier (19) can be inserted and material can be injection molded around the carrier for forming a brush body (25) or a partial brush body, the first injection-molding machine (18) is constructed for forming a thin-walled plate as a bristle carrier (19) and has a shorter cycle time than the second injection-molding machine (24), and the second injection-molding machine (24) is constructed as a multi-compartment injection-molding machine and has a multiple of a number of mold cavities of the first injection-molding machine (18) that each receive a plurality of the bristle carriers (19) that are to be molded into one of the brush bodies.
