Definitions

• the invention relates to a hair piercing machine for bribing an artificial hair piece (toupee) according to the preamble of claim 1.
• the assembly of the circuit boards is carried out in such a way that the circuit board is arranged in a fixed manner and the assembly arm holding the element to be inserted visits the assembly location under program control and uses the element. The assembly arm then moves in the direction of the element store in order to pick up the next element.
• the disadvantage here is the complex and space-consuming mechanism for moving the piercing needle head.
• the needle head must contain all elements such as stepper motors, gears, etc., so that great demands must be made on the weight reduction of the individual parts.
• Another problem with bribing a hair piece is that the individual puncture points are not determined by calculations such as e.g. B. with a circuit board based on the circuit diagram, but each must be determined depending on the person. This would have to be done in a special scanning device. The evaluation of the data could be used to control the piercing needle.
• the object of the invention specified in claim 1 is to provide a hair piercing machine according to the preamble of claim 1, in which the material expenditure and the moving masses are as small as possible.

• the machine can be operated with just a few hand movements.
• the T-shaped holding device only needs to be rotated in order to bring either the scanning device or the piercing needle into the working position above the positive shape.
• the development according to claim 3 makes it possible to selectively set different independent positions of the Halme tearme without adjustment, and prevents the holding arms from being moved out of the working position unintentionally.
• the holding arms can be pivoted away so that the positive form is completely freely accessible.

• the development according to claim 6 extends the adjustment possibility of the positive shape in the event that the head shape has larger flat surfaces.
• the development according to claim 7 facilitates the assembly of the hair piece and reduces the cost of materials.
• the development according to claim 9 reduces the effort for pivoting accommodated in the housing of the machine and enables the coordinated tilting of the positive shape and the needle holder.
