The invention relates to a method for shaking out a sprue (30) of metal lost-pattern castings (32), the sprue of castings being formed in a shell (1), in which at least one blade is moved by means of a machine without making contact with the sprue, so that the blade engages with the shell, breaks the latter into a plurality of fragments, and separates from the sprue at least one portion of the shell; and to a machine for implementing the method. |
