  • Patent number: 8534769
    Abstract: The tips of pointed bristles are mechanically processed in order to remove any corroded threads or residual threads from the tip. Mechanically processed pointed bristles are fed to a receptacle recess of a tool in bundles, and aligned by means of a pin guided in the receptacle recess. The pointed bristles are pushed through the passage of the bristle carrier plate, and the end section are subsequently melted by means of a heating die in order to attach the pointed bristles to the bristle carrier plate. The mechanical processing of the tips of the bristles enables an error-free further processing of the pointed bristles utilizing the bristling method, particularly the AFT method.

  • Patent number: 8186765
    Abstract: The present invention provides a method of manufacturing a toothbrush having needle-shaped bristles and a toothbrush manufactured using the method. The method of the present invention includes the step of grinding bristles, which have been set in a head part of a toothbrush, using a grinder provided with protrusions (11) having heights ranging from 1.5 mm to 7 mm. According to the manufacturing method of the present invention, a toothbrush having needle-shaped bristles can be manufactured without a separate chemical immersion process such that the thicknesses of the end points of the needle-shaped bristles range from 0.01 mm to 0.03 mm and the lengths of the tapered portions thereof range from 3 mm to 9 mm. Furthermore, because the process is simplified, the time required for production and the defective proportion is markedly reduced. As well, in the present invention, materials other than polyester can be used as the material for the bristles, unlike the conventional arts, in which this is impossible.

    Abstract: The invention relates to a method and a device for producing a toothbrush or part thereof by the two-component or multi-component injection-molding process. To produce in the brush body segments that are isolated from the rest of the brush body, a mold which comprises three hollow regions is used. Two of these hollow regions that are separate from one another serve for producing the segments and the other regions of the toothbrush from a first component. A third hollow region serves for distributing material to the segments that are isolated from one another and from the other regions, or the corresponding hollow region. The material remaining behind there is removed and sent for disposal. In a further step, connecting elements between the segments and/or the other regions are injection-molded from a second component.

    Abstract: An apparatus is provided for automatically mounting a helix on a radial bristle cosmetic brush, and in particular, a mascara brush. The brush has a twisted wire core and may be mounted to a plastic stem or rod that extends back to a cap/handle combination. The helix comprises a spiral series of adjacent coils. The helix is adapted to be mounted about the core of the brush such that the radially extending bristles of the brush project out between adjacent coils of the helix. The apparatus for mounting the helix on the brush comprises a base supporting a cradle. The cradle receives and aligns a helix and a brush. A pusher mounted next to the cradle slides the brush toward the helix such that the tip of the brush comes to rest against one end of the helix. A gripper holds the other end of the helix so that the helix is stationary relative to rotation of the brush. A rotator has a pair of jaws supporting wheels that grasp the stem of the brush. At least one of the wheels is driven to rotate the brush.

  • Patent number: 6880896
    Abstract: A device for manufacturing brush products, in particular toothbrushes, with a bristle magazine having a feed chute for receiving filaments of precut length arranged in a dense array transverse to the longitudinal axis of the bristle magazine. The feed chute has a discharge opening which is bounded by a bristle picker closing the discharge opening from outside, and serves to feed filaments to a recess provided on the bristle picker. The recess receives only a predetermined quantity of filaments, combining them into tufts which are then transferred to further stations for further processing. According to the invention, the feed chute has a magazine bottom on which the discharge opening is formed. The magazine bottom is further shaped in an arcuate configuration tapering essentially in the direction of the discharge opening. This produces a steady filament flow in which dead zones are not allowed to develop.

  • Publication number: 20040240926
    Abstract: A brush for applying a substance to keratinous fibers may include a twisted core defining turns and bristles extending from the twisted core. The bristles may be clamped between the turns of the twisted core, and the bristles may include at least two deformed bristles clamped between two adjacent turns of the twisted core. Each of the at least two deformed bristles may have a length wherein at at least one point along the length each of the at least two deformed bristles includes either removal of material at the at least one point, stretching of material at the at least one point, or flattening at the at least one point. Each of the at least two deformed bristles may extend outward from the at least one point in a non-radial manner with respect to the twisted core.

  • Patent number: 6726789
    Abstract: In a method for the production of brushes consisting of a bristle support and bristles mounted thereon and combined to at least one group having a defined cross-section with at least two different types of bristles, the bristles of a bristle type are combined into a partial group and the partial groups forming a bristle group are combined into said bristle group and subsequently, the bristle group is mounted to the bristle support. The bristles of each partial group are formed in a surrounding guide of a shaping device into a cross-section corresponding to their partial cross-sections in the bristle group, and the partial groups are then combined while maintaining their partial cross-section in the guides to form the cross-section of the bristle group. A device for carrying out this method and brushes produced in this fashion are also described.

    Abstract: An apparatus and method for producing brushes. The bristle bundles are loaded into a magazine which includes part of a cavity for an injection mold. The magazine is mated with the remainder of the injection mold and the brush handle injection molded around the bristles. The bristles may be profiled, trimmed, end-rounded, fused, or otherwise processed before the handle is injection molded. In addition, the handle of the brush may be formed in two injection molding steps of two different materials. An apparatus is taught which enables the brush to be produced, optionally ornamented, and packaged on a single machine.

  • Publication number: 20030217759
    Abstract: The present invention relates to a method and system of manufacturing a cosmetic applicator in which a predetermined pattern of flocking bristles are dispensed toward the applicator and are adhered to the applicator by an adhesive. The flocking bristles can be dispensed using a flocking dispenser. The flocking dispenser is moveable in a longitudinal direction forward and backward along the sides and tip of the applicator. During or after movement of the flocking dispenser, the applicator can be rotated around its longitudinal axis. The movement of the flocking dispenser and rotation of the applicator can be controlled to provide the desired pattern of flocking bristles. The density of distribution of the flocking bristles can be controlled by varying the speed of movement and rotation of the applicator and the amount of flocking bristles which are dispensed from the flocking dispenser. For example, a high density of flocking bristles can be applied to extend radially from the tip.
