  • Patent number: 6089846
    Abstract: A feed device for an injection chamber of a pressure die-casting or injection machine or for a press tool or a forging press die transfers a billet into an injection chamber or die press. The billet may be of metal or plastic, filled or unfilled, and in a liquid, solid, semi-liquid or semi-solid state. A support with a horizontal axis receives and houses the billet. A ram moves the support and thus transfers the billet into at least one heating system. The ram that transfers the billet also moves the support in a horizontal translational motion transporting the billet from the heating position to a position lying vertically above the injection chamber of the tool or the press die, and then moves the support with a rotational motion about its axis so as to cause the billet to drop, horizontally, due to gravity, from the support into the injection chamber or into the press die.
