ABSTRACT:
An annular groove (35) is located in an outer surface of an inner toroid (31), and is partly covered by an inner surface of an outer toroid (32). Alternatively, an annular groove (25) is located in an inner surface of an outer toroid (22), and is partly covered by an outer surface of an inner toroid (21). As the toroids are rotated together about different, intersecting axes, an elongated workpiece (W) is introduced into an open portion of the annular groove, advances into the closed portion of the annular groove, and is extruded through a die (48) upon again approaching the open portion of the annular groove, thereby forming an elongated product (P).
