An end-rounding device comprises a movable body comprising an abrasive surface; a gearing for transferring a movement from a motor to the movable body; a providing unit for providing a plurality of bristle filament ends to the abrasive surface, wherein the providing unit comprises a clamping unit for clamping a bunch of filaments, wherein the bunch comprises a multiple of filaments of a bristle tuft; wherein the abrasive surface has a diameter from 80 mm to 300 mm and comprises a concave curvature oriented in the direction of the clamping unit; and wherein the clamping unit is movably spaced from the abrasive surface at a distance. A method of smoothening bristle filament ends utilizes the end-rounding device.

Device for filament end-rounding and a method for end-rounding (tooth)brush filaments

A method for producing a brush head for a toothbrush head is disclosed. The method includes the steps of providing a bristle carrier; providing cleaning elements having first ends which will not be embedded in the bristle carrier and second ends which will be embedded in the bristle carrier, wherein the cleaning elements are selected from at least two different types of cleaning elements or at least two distinctive cleaning elements of the same type; placing the first ends of the cleaning elements in the bristle carrier in a carrier part for holding; and supplying different amounts of heat to the second ends in the bristle carrier by reflecting the heat supplied partially from the carrier part and/or absorbing the heat supplied partially by the carrier part resulting in the second end being molten.

Brush head and method and tool for producing the same

A clamping device for restraining filament tufts in a bristle cluster includes fixed and movable clamping plates. The clamping plates have apertures that are aligned in the unloaded position and that are offset relative to each other in the loaded position. The movable clamping plates can be displaced relative to the fixed clamping plates, and each movable clamping plate secures a specific portion of the bristle cluster.

Clamping devices

The invention is directed to a long-hair cutter unit (LHS) for a dry shaving apparatus (TR), with a dimensionally stable cutting comb ( ) having one cutting teeth row ( ) and at least one bearing surface ( ) for at least one engagement surface ( ) of an arcuately curved, hardened cutting blade ( ) having one cutting teeth row ( ) and held in engagement with the cutting comb ( ) by a pressure of at least one spring element ( wherein the curvature of the hardened cutting blade ( ) is partially configured by means of a forming process such as to ensure conformance and slidable contact of the engagement surface ( ) of the cutting blade ( ) with the bearing surface ( ) of the cutting comb ( ) by means of the partial curvatures as well as their restoring forces under the action of the pressure of the spring element ( ).
