ABSTRACT:
A reciprocatory dry shaver has a head from mounting three elongated cutter heads, one center cutter head and two outer cutter heads extending in parallel with each other. Each cutter head comprises a holder carrying a stationary cutter and a movable cutter driven to reciprocate in shearing engagement with the stationary cutter. The head frame is mounted on a shaver housing from which a reciprocating element projects to drive the movable cutter of each cutter head. The center and outer cutter heads are floatingly supported at individual longitudinal ends by associated center and outer spring members so that each cutter head is vertically movable relative to the head frame. The center spring members are formed in one of the head frame and the associated holder while the outer spring members are formed in the other of the head frame and the associated holders. Thus, the spring members for floatingly supporting the center and outer cutter heads can be effectively distributed to the head frame and the associated holders to enable compact arrangement for a system of floating supporting the three parallel cutter heads within a limited space.
