• a method of wrapping a lock of hair using the hairdressing appliance 2 described above will now be described by considering that the movable protective cover 14 is in the open position and the winding element 11 in the discarded position.
• Such a loopback method comprises the following steps:
• Figure 12 schematizes an example of implementation of the winding step and that in this figure the lock of hair is shown schematically by the reference numeral 40.
• the winding element 11 is rotatably mounted between an initial angular position, corresponding to the beginning of a loopback cycle, in which the winding element 11 is situated substantially opposite to a central portion of the movable protective cover 14, and a final angular position, corresponding to the end of a loopback cycle, in which the winding element 11 is located opposite the fixed protective cover 16 and is maintained in the position approximated by the fixed protective cover 16.
• the final angular position is angularly offset from the initial angular position by an angle of about 90 °.
• the looping method preferably comprises an additional step performed after the step of removing the lock of hair and consisting of automatically repositioning the winding element 11. in the initial angular position.
• the winding element is then biased towards the position spread by the biasing member.
• FIGS. 13 and 14 show a hairdressing appliance according to a second embodiment which differs from the first embodiment essentially in that the movable guiding element 27 is mounted mobile in translation relative to the mandrel 6, and in that the actuating device 28 comprises a toothed wheel 35 mounted to rotate about an axis of rotation perpendicular to the longitudinal axis A of the mandrel 6, and a rack 36 provided on the movable guide member 27 and configured to cooperate with the toothed wheel 35 so that a rotation of the toothed wheel 35 in a first direction of rotation S3 induces a translation of the movable guide member 27 towards its operating position and that a rotation of the toothed wheel 35 in a second direction of rotation S4, opposite to the first direction of rotation S3, induces a translation of the movable guide member 27 to its standby position.
• the actuating device 28 comprises a toothed wheel 35 mounted to rotate about an axis of rotation perpendicular to the longitudinal axis A of the mandrel 6, and
• control unit is configured to automatically control the rotation of the toothed wheel 35 according to the first direction of rotation or the second direction of rotation as a function of the movements of the element. winding 11 between its close and spaced positions.
