Abstract
Abstract RANDOMLY ARRANGED SHALLOW CLOSURES ARE GUIDED BETWEEN OPPOSED ROTARY BRUSHES. CLOSURES ENTER BETWEEN THE BRUSHES WITH THE OPEN END OF A CLOSURE FACING EITHER ONE OR THE OTHER OF THE OPPOSED BRUSHES. AS A CLOSURE PASSES BETWEEN THE BRUSHES, THE BRISTLES OF ONE BRUSH ENTER THE OPEN END OF THE CLOSURE, THE OPPOSING BRUSH BEARING AGAINST THE CLOSED END. THE ENGAGEMENT OF THE BRISTLES WITH THE OPEN END OF A CLOSURE CAUSES THE CLOSURE TO MOVE TO A POSITION WITH ITS OPEN END FACING UPWARDLY WHEN RELEASED BY THE BRUSHES.
