ABSTRACT:
An apparatus for extruding a powdered material forms an elongated pellet. The extrusion apparatus includes a connection mechanism arranged between the inlet and the constriction passages for continuously connecting two successively charged portions of the powdered material when the powdered material is repeatedly charged. By this mechanism, the formerly charged and semicompacted portion of the powdered material and the border surface upon the subsequent portion are broken, either by a core piece or a modified die cavity, whereby the portions of the powdered material are merged with each other before the constriction.
