Abstract
Earplugs are formed by extruding an elastomeric material (12) forwardly (F) through an extrusion head (14) so a forward portion of the extrusion enters a shaping cavity (50A). The forward portion of the extrusion is severed from the rest of the mass being extruded to form a globule. The globule is allowed or forced to expand in the cavity, or the cavity is formed of parts that compress the globule, to shape the globule to the shape of the cavity.
