Abstract
A brush manufacturing machine (1) has a first injection-molding machine (18) for the region-by-region injection molding of material around the bristle bundles (7) held in cartridges (9) and for forming a bristle carrier (19) connecting the bristle bundles (7) and also a second injection-molding machine (24) in which the bristle carrier (19) can be inserted and material can be injection molded around this carrier for forming a brush body (25) or 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). At least the second injection-molding machine (24) is constructed as a multi-compartment injection-molding machine and has a multiple of the number of mold cavities of the first injection-molding machine (18).
