ABSTRACT:
A hair removal device having a plurality of spring-loaded tweezers mounted on a rotary head and arranged to open and close during rotation, to trap and pluck skin hair over a relatively wide area. In a preferred embodiment, the rotary head spring-loaded tweezer design is provided as a hand-held, motor-powered depilatory device having a rotor provided with a plurality of tweezers having fixed and pivotable elements mounted on either side thereof, with the pivotable elements being operated by a set of roller pairs mounted so as to engage the tweezer upper ends. As the rotary head rotates about a shaft, the tweezer upper ends pass between the roller pairs and are depressed and released in synchronous fashion, causing them to open and close. When passed over the skin, the tweezers on the rotary head operate in two-sided fashion by opening and closing over a wide area, grasping skin hair in this area and plucking it as the tweezers close, to perform the hair removal function.
