<p>In this method for row-wise separation of rectilinear, plastic porous concrete bodies formed by longitudinal and transverse cutting of a rectilinear plastic porous concrete block preferably standing on edge. After turning back through 90 DEG , the cut block is so placed with its major side surface on a plurality of parallel laminae for the separation and so that its longest side edge runs parallel to the direction of the laminae and that each row of porous concrete bodies is supported on at least one lamina. Before the separation, a clamping force is exerted from above on the upper ends of all the porous concrete bodies of the row to be separated. Independently thereof, a clamping force from above is exerted on the upper ends of all the porous concrete bodies of the stationary row in contact with the row to be separated. This clamping force is maintained during the separation and during the displacement of the lamina in the separating direction, a like directed displacing force is exerted synchronously on the upper ends of the porous concrete bodies carried by the separating lamina.</p> |
