Process and apparatus for forming of set layers from brick blanks

摘要

An improved process and apparatus for forming layers of bricks in which rows within the layer can have the same or differing orientations. The bricks are conveyed in closed or substantially closed rows along a first conveyor. Two other conveyor systems are fed therefrom. On one of these two other conveyor systems, bricks are moved initially to a displacement device and spread apart in a direction longitudinally of the row and are thereafter transferred downstream to form, on a conveyor, a layer or partial layer. When partial layers are formed, that partial layer can be supplemented by transferring a layer of rows of bricks from a preparatory layer formed on the other conveyor system. When such bricks are transferred from the preparatory layer, they are simultaneously rotated through 90 DEG prior to their being deposited to complete the partial layer.
