FIELD OF THE INVENTION

[0001] The invention relates to an apparatus for removing one individual hair/fiber at a time from a tuft using a gripping device.

PROBLEM TO BE SOLVED

[0002] The object of the invention is to obtain an apparatus for removing one individual hair/fiber at a time from a tuft using a gripping device, which enables targeted removal of one individual hair/fiber at a time from a tuft with maximum accuracy meaning with an error rate approaching zero. If by chance the apparatus doesn't collect a single hair/fiber from a tuft, this should also be correspondingly considered by the apparatus according to a sub-object.

SUMMARY OF THE INVENTION

[0003] The object is achieved in that a first gripping element has a wedge-shaped groove oriented towards the second gripping element and a second gripping element has an essentially flat counterpressure zone, wherein the first gripping element is tapered on the side of the wedge-shaped groove (taper A), whereby an individually removed hair/fiber from a tuft is fixated between the wedge-shaped groove and the counterpressure zone.

BRIEF DESCRIPTION OF THE DRAWINGS

[0004] The invention is described in more detail by means of an exemplary embodiment.

[0005] The following is shown:

[0006] FIG. 1 shows a perspective representation from above, which is a view of a part of the apparatus;

[0007] FIG. 2 shows a view from above of the apparatus according to FIG. 1, but with a tuft of hair or fibers between a first and a second gripping element;

[0009] FIG. 4 shows a top view of the first gripping element with a conical tip;

[0010] FIG. 5 shows a top view of the first gripping element with an oblong, rectangular pyramid tip;

[0011] FIG. 6 shows a top view of the first gripping element with a quadratic, pyramid tip;

[0012] FIG. 7 shows a top view of the second gripping element with a counterpressure zone that is arranged transversely with respect to groove length D1-3;

[0013] FIG. 8 shows a view from above of the apparatus according to FIG. 2, but with a first and a second shank;

[0014] FIG. 9 shows a view from above of the apparatus according to FIG. 8, but in a first phase of the removal process for an individual hair/individual fiber;

[0015] FIG. 10 shows an enlarged representation of the view according to FIG. 9;

[0016] FIG. 11 shows another enlarged representation of the view according to FIG. 10, but in a phase of removal of an individual hair/individual fiber from a tuft;

[0017] FIG. 12 shows the representation according to FIG. 11, but in an enlarged view and in a reduced perspective from above;

[0018] FIG. 13 shows the representation according to FIG. 9, but in an exceptional condition of non-collection of a hair/fiber;

[0019] FIG. 14 shows the representation according to FIG. 1, but with a rotation-symmetrical disk as a first gripping element and a cylindrical disk as a second gripping element;

[0020] FIG. 15 shows an enlarged representation of the view of a ring groove of the disk according to FIG. 14; and
