ABSTRACT:
A hang-type earmuff has a unitary, seamless core of flexible plastic in a truncated, conical configuration. A cover extends across the convex outer surface of the core and a liner extends across the concave inner surface of the core. The liner is attached to the core by providing a sheet of lining material, securing the lining material to the convex outer surface of the core adjacent the central opening thereof, removing the central portion of the lining material corresponding with the core opening, folding the lining material over the edge of the core defining the opening, through the opening and across the concave inner surface of the core and securing the lining material at the peripheral edge of the core. The cover is fitted to the core over a fixture to provide ample material to extend around the wearer's ear. The cover may be sewn or welded to the liner.
