Abstract
A table for orthogonally sorting flat workpieces comprising a tray with freely rotatable carrier balls protruding from both surfaces of the tray, an arrangement engaging the balls to support the balls and to rotate them in either direction along a first line of motion, this arrangement being either a continuously moving belt or a plurality of parallel positioned rollers. The table also includes an arrangement for obtaining relative movement between the belt or parallel rollers and the tray to cause a rotation of the balls along a second line extending perpendicular to the first line.
