Abstract
In a shutter (3) for a dry-shaving apparatus, which shutter serves for optinally covering or exposing a shear foil of said apparatus and which comprises an elastic carrier (11) and spaced-apart slats (10), the inherently stiff slats, viewed in the longitudinal direction of the shutter, are successively enveloped at least partly by the elastic carrier (FIG. 1 and FIG. 5). Two-step injection moulding processes are proposed for manufacturing such a shutter.
