- the disk portion shape of these transverse ribs 25, 26 also makes it possible to have a more or less V-shaped flared shape between the transverse ribs 25, 26 arranged facing the two walls 22a, 22b of the slot. 7, which also promotes the positioning of the wick in the slot 7.
- This disc shape could be replaced by the transverse ribs 25, 26 by a triangular, which would also make it possible to form a V shape between the transverse ribs 25, 26 disposed vis-a-vis the walls 22a, 22b.
- the apparatus 1 comprises a stationary finger 27, or fixed finger, consisting of a rigid piece which is fixed at the contour 9a of the extraction opening 9.
- This stationary finger 27 has several functions. Firstly, the stationary finger 27 makes it possible to immobilize the wick in rotation during its winding so as to prevent the wick from rotating around the mandrel 10. In addition, this stationary finger 27 must ensure the demolding of the wick. buckled without damaging it. Finger stationary 27 is oriented perpendicular to the mandrel 10, that is to say perpendicularly to the third axis X3, as illustrated in particular in Figure 2 and 7. The inclination of the immovable finger 27 therefore depends on the inclination of the angle a.
- the angle ⁇ formed between the locking side face 28a and a straight line d1 from the center 29 of the mandrel 10 to the base 30 of the locking side face 28a, as illustrated in FIG. 8, forms an angle of between 0 ° and 35 °.
- this angle ⁇ is 25 °.
- the second lateral locking face 28b which is arranged symmetrically to the first locking side face 28a, along the plane P. In this way, the lock of hair tends to slide towards the base 30 of the finger stationary 27 only towards its end 27a.
- the immovable finger 27 extends from the cylindrical contour of the mandrel 10 over a height h1 between 6 mm and 18 mm, preferably a height h1 equal to 12 mm. A higher height h1 may penalize demolding, and a lower height h1 may not lock the wick enough.
- the stationary finger 27 is spaced from the free end 10b of the mandrel 10 by a distance e1 of between 1 mm and 5 mm, preferably this distance e1 being equal to 3 mm.
- This distance e1 depends on the height h1 retained for the stationary finger 27.
- said mandrel 10 has a diameter D between 20 mm and 25 mm, preferably 22 mm.
- the immovable finger 27 comprises an inner face 31 arranged opposite the free end 10b of the mandrel 10.
- the inner face 31 is curved or concave, as illustrated in particular in FIGS. 3 and 8, which allows to accompany the expulsion of the lock of curly hair during demolding.
- the lower end 31a of this inner face 31 must be as far as possible below the mandrel 10, so that during demolding, the hair does not pass behind this immovable finger 27, which would block them.
- This lower end 31a should not be too marked a tip, but have a rounded shape to properly direct the curly lock on the inner face 31, and not on the underside of the immobile finger 27.
- the stationary finger 27 includes an internal face
- the stationary finger 27 is fixed detachably vis-à-vis the contour 9a of the extraction opening 9 or close thereto.
- the stationary finger 27 comprises a lower portion 33 provided with an orifice 34 allowing a fastening by screws 35 vis-à-vis the front lateral face 2b of the casing 2, as illustrated in FIGS. 8.
- This removable attachment advantageously makes it possible to replace the immovable finger 27 to best adapt it to the type of hair to be curled or when it is worn, in order to limit as much as possible the friction of the curled lock during demolding.
- the apparatus 1 comprises a heating element 36 arranged inside the mandrel 10 so as to heat it and to heat the lock of hair.
- a heating element 36 is known to those skilled in the art, it does not so will not be detailed. It is also possible to envisage other heating means arranged in the winding chamber 8, for example on the inner cage 17 so as to heat the wick in the second spacing 19 between said inner cage 17 and the winder 11.
- the housing 2 of the apparatus 1 is manipulated by the handling handle 3, its side face 2a, which has the extraction opening 9, being positioned against the scalp during the various operations of the looping.
- the arrangement of the handle 3 in the extension of the slot 7 facilitates the handling of the apparatus 1.
- the wick is positioned inside the slot 7 and then guided by the flanges 20a, 20b into the second 19.
- the introduction of the wick in the notch 14 occurs naturally, without the need for inclination the wick relative to the housing 2 and the slot 7 to perform its proper introduction into the slot 14.
- the rotation of the reel 1 1 is then triggered by one of the control buttons 5 or 6, which allows at one of the hooks 16a, 16b - depending on the direction of rotation - to grasp or catch the wick near the scalp.
- the configuration of the reel 1 1 with its surface of revolution disposed around the mandrel and its notch 14, advantageously allows to curl the lock of hair around the mandrel 10 in the inner chamber defined by the first spacing 12, and around the surface of revolution of the reel 1 1 in the outer chamber defined by the second spacing 19.
- the wick spins in the bottom 24 of the walls 22a, 22b of the slit 7.
- guide means are conceivable within the scope of the invention.
- slot 7 may be provided with only V-shaped walls 22a, 22b, without any transverse rib 25, 26, or conversely transverse ribs 25, 26 may be provided on walls parallel to one another, forms transverse ribs disc portion or triangle alone to define a flared or V-shaped.
- corrugations 37, 38 arranged along the length of the two walls 22a, 22b between the transverse ribs 25, 26 , as illustrated in Figures 1 and 2, which also contribute to reducing the friction of the lock of hair on said two walls 22a, 22b.
- the slot 7 comprises two walls 22a, 22b which are inclined at a V angle to each other and which have corrugations 37, 38 as described above for the variant embodiment of Figures 1 to 9.
- the parts 23a, 23b of the two walls 22a, 22b which consist of a single piece with a bottom 24 common, as described for the variant previous, with a slight difference since the bottom 24 is not rounded but flat, as can be seen in this figure 1 1.
- the slot 7 comprises two walls 22a, 22b which are inclined V between them and which have corrugations 37, 38 as described above.
- the parts 23a, 23b of the two walls 22a, 22b consist of a single piece with a bottom 24 common which has a curved or spoon shape, as can be seen in this figure 1 1, this form also allowing guiding the lock of hair in the slot 7, during its winding around the reel 1 1 and the mandrel 10.
- the design variants of the reel 1 1 and the stationary finger 27, as described above also apply.
- the second axis X 2 in which the revolution form of the housing 2 is defined, is perpendicular to the first axis X 1, that is to say inclined by an angle ⁇ equal to 90 ° with respect to said second axis X2.
- the variant embodiment illustrated in FIGS. 1 to 4 is perpendicular to the first axis X 1, that is to say inclined by an angle ⁇ equal to 90 ° with respect to said second axis X2.
- the second axis X2 merges with the third axis X3 of the mandrel 10 and the reel 1 1, that is to say that the second axis X2 is inclined by an angle ⁇ with respect to the first axis X1 corresponds to the inclination angel a of the third axis X3 with respect to said second axis X2.
- the angle ⁇ may be between 50 ° and 90 °; when the angle a is 80 °, the angle ⁇ may be between 80 ° and 90 °; and for the preferred value of the angle a equal to 70 °, the angle ⁇ may be between 70 ° and 90 °.
