摘要
According to the invention, calibrated rings are obtained by superficially vulcanizing extruded or profiled extrudate at the exit of an extrusion head (T), then by cutting this vulcanized extrudate into portions by means of a conical cutting device (C), subsequently by butting the two ends, in the respective form of a conical tip and a funnel, of each portion (t) together under hot conditions and under a controlled pressure, in order to obtain a ring blank which is then engaged between the half-cavities of a mold (Mo), where it undergoes shaping and vulcanization by the heating of the latter and thereafter deburring as a result of a shearing action produced by a push device (D) causing the half-cavities to slide in the closed position in the frame of the mold, before causing the opening of the latter by means of a device (G) and the release of the calibrated and superficially clean ring obtained.
