Abstract

In connection with making cast paving bricks of concrete with rectangular basic shape, sometimes there is performed a finishing treatment of the bricks by 'rumbling' where the bricks otherwise organized on pallets or a casting board are transferred to a cylindric drum where these are tumbled with the purpose of achieving a surface with particular appearance. It has appeared that rumbled bricks, for price reasons, are preferred to be delivered in bulk, as a subsequent manually performed pelletizing is a relatively expensive element. Thus there is indicated a sorting unit including a conveyor with a conveyor belt over the surface of which, between a receiving area for the bricks and a delivery area, there are mutually spaced guide bars disposed obliquely in relation to the direction of movement (F) of the conveyor, by which the bricks are guided in a row with the same orientation for subsequent pelletizing by machine.
