Abstract (en)

A machine (1) for shaking out foundry castings (G) comprises a structure (2) for supporting the castings (G) to be shaken out and vibrator means (8a, 8b) for selectively producing the vibration in the support structure (2). First and second vibrator means (8a, 8b) are provided and can be operated selectively (13, 21) in at least one first operating condition, in which the vibrator means (8a, 8b) operate in phase opposition so that the support structure (2) remains substantially stationary, and one second operating condition, in which the vibrator means (8a, 8b) operate in phase coincidence so that the support structure (2) is subjected to vibration. <IMAGE>
