Abstract
A vibrator table apparatus includes a primary table member driven by at least two vibrators. The vibrator long axes are spaced from and angular to one another. The table member has a number of cylindrical holes formed through it. That is, the holes and "through-holes" and extend between the upper and lower surfaces of the table member. The total of the areas of the holes is in the range of 40% to 60% of the area defined by the perimeter edge of the table member and, most preferably, is about 50% of such area. The upper surface of the table member has a number of sockets formed in it for receiving respective standoff studs. A product support platform is coupled to the standoff studs and is in a spaced relationship to the upper surface.
