<p>The spaces between the ribs on the table (8) increase in the movement direction of the objects so that they fall downwards through them. The objects are moved by beams (2) which move forwards and backwards. The beams are operated individually so that the backward movement directed towards the narrow part of the spaces is quicker than the forward movement. The beams are individually secured by springs (6, 7) which, in fact, produce their return movements.</p> |
