Problems solved by technology

This method is at least theoretically possible to produce smooth bristle shafts, but requires highly dependent elongation methods and complex molds
However, despite the high complexity of the mold, it does not allow the operator to choose the shape of the bristle feet
Specifically, the tool cannot be used to produce bristle feet with undercuts

Embodiment Construction

[0032] figure 1 A longitudinal section of the bristle 10 is shown, which is selected along the longitudinal axis L of the bristle. A bristle shaft blank 12 can be seen here, which has a bristle shaft 14 , a bristle foot 16 and a bristle head 18 . The bristle shaft blank is formed in the hollow space 36 of the first molding fixture 30 . The second molding fixture 32 and the third molding fixture 34 form a hollow space 38 in which the bristle feet 16 are formed. The bristle shaft blank can be removed from the molding fixture by moving the first molding fixture 30 along the longitudinal axis L, i.e., as figure 1 Move up as shown. The second and third molding jigs are then pulled apart in a direction perpendicular to the longitudinal axis L as indicated by left and right arrows A .

[0033] figure 2 A bristle 10 is shown that may be manufactured according to the methods disclosed herein. The shaft 14 of the bristle 10 is free of ridges and is bounded above by the bristle he...

Abstract

The invention relates to a hairbrush (40), bristles (10) for use in a hairbrush, and method for the production of a hairbrush and such bristles. Particularly, the invention discloses a method for producing a brush in which moldable material is placed in a multi-part, separatable mold tool and a bristle is produced having a bristle foot (16) and a bristle shaft (14), wherein a bristle shaft blank (12) is molded using a first molding jaw (30), wherein moldable material is placed in a mold hollow space (36) of the first molding jaw and removed from the mold hollow space of the first molding jaw,wherein the mold hollow space of the first molding jaw is maintained and the bristle foot is molded in a second molding jaw (32) and a third molding jaw (34), wherein the second and third molding jaws together form a second mold hollow space (38), the shape of which substantially corresponds to the shape of the bristle foot to be formed, and the second mold hollow space is filled with the moldable material and the first and second molding jaws are separated.

Description

technical field [0001] The present invention relates to a hairbrush, bristles for a hairbrush, and a method for manufacturing a hairbrush and bristles of the type. The present invention can be used with many very different hair brushes. The bristles described herein can even be used in brushes that are not intended or not primarily intended for brushing hair. It would also be very suitable to use the bristles in massage brushes. Another suitable application may be the use of the bristles in hair care appliances which also heat the hair by warming the air or warming the contact surface. Such devices are marketed as stylers or curlers. Background technique [0002] GB 601.371 (Denman) discloses a hairbrush with non-metallic bristles. These bristles taper towards the tip and have bristle feet that serve to anchor the bristles securely in the rubber pad, where the bristles are inserted by first passing the tip through an opening in the pad, and using the brush body Apply pr...
