Abstract
A two mass vibratory apparatus for processing work material includes a bed defining a transport surface for receiving the objects, an elastic amplifier having a first end connected to the bed and a second end, and a base connected to the elastic amplifier second end. A linear actuator is mounted on the base and adapted to generate a linear vibratory force that is amplified by the elastic amplifier thereby to move the bed in a vibratory motion, so that the work material moves in response to the vibratory motion of the bed.
