Question

What are the production stages and labor requirements for each stage of production for a hairbrush?

Answer 1

production stages :

This item is usually disposed of when it can not be repaired. It would be placed in a landfill. It probably would not be recycled. It could possibly be reused to brush a dog or clean shoes.

Step 1 Raise and Extract

Step 2: Process

Step 3: Manufacture

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.

The invention relates to a hairbrush, bristles for use in a hairbrush, and method for the manufacture of a hairbrush and such bristles. The invention can be used in a number of very different hairbrushes. The bristles described here could even be used in brushes not intended for or not primarily intended for brushing hair. Using the bristles in massage brushes would also be particularly suitable. Another suitable application would be to use of the bristles in a hair-care device that also heats the hair, either via warm air or a warm contact surface. Such devices are marketed as stylers or curlers.

A process for manufacturing bristles is known from DE 2155888. Disclosed in this patent is a multi-part, separable mold tool for molding a bristle with a bristle foot and bristle shaft. This process makes it possible, at least in theory, to produce smooth bristle shafts, but requires a highly involved elongation process and a complex mold tool. Despite the complexity of the mold tool, however, it does not allow operators to select the shape of the bristle foot; in particular, the tool cannot be used to manufacture a bristle foot with an undercut.

The purpose of the present invention is to provide bristles, brushes and methods for the production thereof that represent an improvement over the state of the art. The bristles and brushes should be especially gentle to hair and the scalp. The manufacturing processes are to be cost efficient, suitable for mass production, and produce little waste. In particular, the processes are to result in safe, gentle bristles and brushes, even when production standards are less than perfect.
