ABSTRACT:
A flask adapted to contain a pattern and sand is resiliently supported in a controlled orientation and vibrational forces are imparted to the flask including a horizontal force component causing generally horizontal oscillating movement of the flask and alternative oppositely directed vertical force components maintaining the flask in a controlled orientation during the generally horizontal oscillating movement thereof. The vertical force components are adapted to counteract rotational inertia of the flask, pattern and sand.
