A method of making a cleaning element carrier for a toothbrush comprises: providing at least two pluralities of loose filaments of a predefined length and different from one another in at least one of filament material, filament diameter, filament cross-section, filament shape, presence or absence of additives, presence or absence of a coating, and any combination thereof; providing a hole-perforation plate having a front surface, a back surface, a thickness therebetween, and a plurality of holes shaped and arranged according to a predetermined pattern; picking filaments from the pluralities of loose filaments; providing an energy source; arranging a plurality of bristle tufts in a fusing position in the hole-perforation plate so that ends of the bristle tufts are disposed at different distances from the energy source, wherein the distances are adjustable according to the at least one property, wherein the plurality of bristle tufts includes bristle tufts comprising an inner portion bristle tufts comprising a peripheral portion, and wherein a distance between the energy source and the ends of the bristle tufts comprising the inner portion is shorter than a distance between the energy source and the ends of the bristle tufts comprising the peripheral portion; applying energy from the energy source to the ends of the tufts until fuse balls are formed at the ends of the tufts; transferring the tufts to a molding position in the hole-perforation plate so that a distance between a bottom edge of at least one fuse ball of at least one bristle tuft and the front surface of the hole-perforation plate is different from a distance between the bottom edge of the fuse ball of said tuft and the front surface of the hole-perforation plate in the fusing position; over-molding the fuse balls with molten plastic material thereby forming a cleaning element carrier.

Improvements in the technical field of brush manufacturing include providing a profiling device (25) for profiling a set of bristles (3) of a brush (1) to be manufactured, which profiling device is set up to profile a cleaning side (27) of the set of bristles by axially displacing bristle filaments (4) of the set of bristles (3) relative to their longitudinal axes.

A method for separating bristle bundles (5) from a supply (10) of loose bristle filaments (11) is provided, in which a bundle separator (13) having a separating notch (14) is moved in a separating movement past the supply (10) of loose bristle filaments (11), in the process separating a bristle bundle (5) from the supply (10) which makes its way into the separating notch (14). When the separating movement is carried out, the separating notch (14) changes its direction of movement in a separating region (16) on the supply (10) at least twice, preferably at least thrice.

A crimper for crimping nail brushes includes a pair of guide shafts and an upper jaw coupled to the pair of guide shafts adjacent an upper end portion of the guide shafts. A lower jaw is moveably coupled to the guide shafts, and includes a lower plate and a lower jaw body coupled to the lower plate. An adjustment plate is coupled to the lower end portions of the guide shafts such that the lower jaw is located between the upper jaw and the adjustment plate. An actuating cam is configured to interface with the lower plate and the adjustment plate, with the actuating cam being rotatable between neutral and actuated positions. The upper jaw and lower jaw move toward each other as the actuating cam rotates from the neutral position toward the actuated position and assume a prescribed distance therebetween when the actuating cam is in the actuated position. A size adjustment dial may be positioned on the device to be selectively rotatable to facilitate adjustment of the crimping jaws based to correspond to the size of the nail brush.

A separating device (1) for separating bundles of bristles from a store (2) of loose bristle filaments (3). The separating device has a material box (4) for receiving the store of loose bristle filaments (3), a bundle separator (5) having at least one separating notch (6), and at least one counter piece (7). The bundle separator (5) is movable with the at least one separating notch (6) through a separating region (8) at the material box (4) in order to separate bundles of bristles, and the at least one separating notch (6) is movable with the bundle separator (5) along the counter piece (7) into a bundle delivery position (33). The bundle separator (5) has, on its front side (11) facing the counter piece (7), a profile (12) with which the bundle separator (5) overlaps the counter piece (7) when the separating notch (6) is at the counter piece (7).

A device used in the technical field of producing bristle products. The device (1) includes a tufting tool (3) for tufting bundles of bristles (4) into a provided bristle carrier (5) and a bristle displacer (6) for displacing already tufted bundles of bristles from a tufting region of the tufting tool (3). The tufting tool (3) and the bristle displacement element (6) are connected to a common drive shaft (9) of the device via a respective coupling gear mechanism (7) and/or (8) and are driven by same.
