Definitions
- the invention relates to a device for producing a hair replacement part, in which replacement hairs are anchored in a flat substrate and emerge from one of its two surfaces, which has at least one piercing needle.
- a piercing needle became known from the US 3980 090, which, however, has not prevailed in practice.
- This is a hollow needle with a beveled tip, similar to a cannula, dar.
- the intention of this invention was, by frontal piercing the hollow needle in a hair tufts a single hair in the cavity, with supernatant to the outside, record. During the subsequent piercing of the hollow needle in a substrate, the hair should remain anchored in this when retracting the hollow needle.
- the piercing needle has a conically tapered puncture end and is provided in the region with a running substantially parallel to the taper slot for hair picking.
- the inventive shape of the piercing end of the piercing needle differs significantly from the previous forms by the end is neither hollow nor curved, but tapers, and the hair receptacle is made neither by entering a cavity nor by an end hook, but by a frontal, lateral slot.
- This design allows a secure capture of one to two hairs per penetration in a hair tufts and a reliable anchoring of these hairs per penetration into the substrate of a hair replacement part.
- the optimal length of the tapered end of the puncture is substantially equal to 4 times the diameter of the puncture needle. It has also been shown that it is favorable if the length of the slot is about half the length of the tapered insertion end and the width of the slot about one 10th of the diameter of the piercing needle.
- FIG. 1 and 2 each show a section of a cross section through a hair replacement part
- Fig. 3 is a plan view of a strip-shaped hair replacement part
- Fig. 4 the puncture end of a piercing needle according to the invention.
- Fig. 1 illustrates a hair replacement part having a substrate 1 and replacement hairs 2 anchored therein (only one of which is shown).
- the replacement hair 2 is fixed in the substrate 1 approximately perpendicular to the surface, but outside the substrate 1 angled at least 45 ° so that it includes at most the surface of the substrate at an angle of 45 ° and its exit angle of that natural hair is the same.
- Fig. 2 shows in analogous to Fig. 1 representation of a replacement hair 2, which is housed in the substrate 1 in an oblique recess 3, that is, must experience no change in direction at its exit, which is gentle on the hair.
- Fig. 3 shows a hair replacement part, the substrate having the shape of an elongated strip 4, in which the replacement hairs 2 are anchored as shown in FIG. 1 or 2.
- the strip 4 has at least one (in the figure, the upper) non-linear longitudinal boundary 5, in order to ensure a good adaptation to the human head shape.
- Fig. 4 illustrates the puncture end of a piercing needle 6, which is conically tapered and is provided in the region with a substantially parallel to the taper 7 extending slot 8 for hair absorption.
- the length 1 of the tapered insertion end substantially corresponds to 4 times the diameter d of the piercing needle 6.
- the length of the slot 8 is about half of the length 1 of the tapered insertion end and the width of the slot 8 corresponds to about one 10th of the diameter d of the piercing needle. 6
- hair replacement parts according to FIGS. 1 to 3 can be produced which have a maximum of two hairs per penetration 3.
