Abstract: Turning arrangement (2) for concrete products, paving stones/flagstones for paving, curb stones for delimiting and blocks for erecting walls are arranged in a row with uniform orientation (4), the products (4) are advanced to a turning arrangement where the individual concrete product (6) is turned by the force of gravity.

Abstract: Use of more exotic laying patterns in connection with establishing paving stones of concrete blocks for e.g. paving on yards, are not widely used for cost reasons, as the automated laying machines laying the said paving stones in large surfaces at a time require the stones to be delivered in palletised formats which are handled by machine. The only way in which the said stereotype formats can be laid by machine is, if the paving stones are supplied manually, patterned layers on pallets. There is thus indicated a method for automatic sorting of paving stones (2) of different size from bulk condition to e.g. patterned laid palletisable layers in a standard out format, as the stones (2) after being guided into a row (3) are registered by size by a vision based system and guided into arraying lanes (34) from where these may selectively be dispensed in the preferred laying patterns in the said out formats (22).
