Definitions

• the invention relates to a depilating apparatus with a housing, which housing is provided and designed to accommodate a supply of a depilating tape, which depilating tape can be pulled away from the supply and can then be applied to the skin of a person, and which depilating tape, after application to the skin of a person, adheres to the skin along an application length and can then be pulled away from the skin of a person, and with application means for applying the depilating tape to the skin of a person, and with an opening in the housing, which opening is provided and designed for passing the depilating tape through to the skin of a person, and with a wind-up reel, which wind-up reel is provided and designed to take up the depilating tape that was previously adhering to the skin of a person.
• a depilating apparatus of the generic type cited in the first paragraph above is known from patent document EP 0 738 482 Bl.
• the known apparatus is equipped with a rectangular and largely cuboidal housing, which, on a side running transversely in relation to the longitudinal direction of the housing, has an opening for passing through the heated depilating tape to the skin of a person, and which is equipped with a chassis that can be adjusted in the housing in parallel with the longitudinal direction of the housing, on which chassis a supply reel for the depilating tape and a wind-up reel for the depilating tape are rotatably mounted and on which chassis, in addition, a block-shaped heating device is arranged, with the aid of which the depilating tape can be heated and which simultaneously forms the application means for applying the heated depilating tape to the skin of a person.
• the heating device used as the application means can be brought into the area of the opening in the housing, as a result of which, with the aid of the heating device, which is equipped with a press-on surface for pressing the heated depilating tape onto the skin of a person, a section of the depilating tape essentially corresponding to the size of the press-on surface can be pressed onto the skin of a person and, in this manner, can be brought into an adhesive connection with the skin of a person.
• the depilating tape that has been brought into an active connection with the skin of a person, having previously been heated with the aid of the heating device, wherein the depilating wax provided on the depilating tape has been heated so that the depilating wax has softened and therefore was able to enclose hair cools during the adhesion to the skin of a person, wherein a cooling of the depilating wax occurs, with the result that a retention of the enclosed hair on the depilating tape takes place with the aid of the depilating wax.
• the depilating tape, including the hair retained on the depilating tape with the aid of the depilating wax is pulled away from the skin of the person as quickly as possible, i.e.
• the jerking removal of the depilating tape from the skin of a person takes place by means of an abrupt backward movement of the chassis carrying the heating device away from the opening of the housing, after which the depilating tape that has been pulled away from the skin of a person runs within the housing like a loose loop.
• the loose loop mentioned above has to be eliminated by manually rotating the wind-up reel which is rotatably mounted on the chassis, as a result of which the used depilating tape is wound up. Winding manually in this way represents a procedure that is a nuisance to the user and requires additional time, which is generally felt to be not very user-friendly.
• a depilating apparatus in accordance with the invention may be characterized in the manner stated below, namely:
• a depilating apparatus with a housing which housing is provided and designed to accommodate a supply of a depilating tape, which depilating tape can be pulled away from the supply and can then be applied to the skin of a person, and which depilating tape, after application to the skin of a person, adheres to the skin along an application length and can then be pulled away from the skin of a person, and with application means for applying the depilating tape to the skin of a person, and with an opening in the housing, which opening is provided and designed for passing the depilating tape through to the skin of a person, and with a wind-up reel, which wind-up reel is provided and designed to take up the depilating tape that was previously adhering to the skin of a person, wherein a motor accommodated in the housing is provided, and wherein a drive connection is provided between the motor and the wind-up reel, so that the wind-up reel can be driven in rotation with the aid of the motor to wind up the depilating tape that was previously adhering
• the provision of the motor also has the great advantage that the pulling-off of the depilating tape applied to the skin of a person can be undertaken with this motor, as a result of which it is made possible to match the pull-off force and the pull-off speed to the desired requirements in a relatively simple manner since both the pull-off force and the pull-off speed depend on the motor torque and selection is therefore relatively simple by an appropriate choice of motor or by appropriate influencing of the motor. With the aid of a motor of this kind, it is also ensured with a high degree of certainty that a constant pull-off force and a constant pull-off speed will be retained over the entire service life.
• the interruption of the drive connection can, however, also take place automatically, for instance by pressing the application means onto the skin of a person, wherein a control device for control purposes, namely to interrupt the drive connection, is provided between the application means or the support means for the application means and the interruptible drive connection.

• a sharp pull-off angle of this kind is a positive parameter in respect of achieving good depilating results, i.e. good hair removal results.
• the depilating apparatus 1 described above uses so-called hot-wax tapes, which have to be heated before being applied to the skin.
• the measures in accordance with the invention could, however, also be introduced in depilating appliances for so-called cold- wax tape, which cold-wax tape does not have to be heated, so this kind of depilating apparatus can operate without the need for a heating device.
• the depilating apparatus 1 described above uses reels with flanges and with a reel hub with a circular cross-section. However, reels without flanges and with different hub cross-sections, e.g. with an elliptical or polygonal cross-section, may also be used. With regard to the depilating apparatus 1, it should also be mentioned that, in a modification to this depilating apparatus 1, the application roller 40 may also be of a heatable design in order that depilating tape 11 can be subjected to an additional heating process immediately before the application to the skin of a person.
