Abstract

A method and apparatus for cubing paving stones or similar stones which are not adapted to forming a self-supporting unit through the means of pressure applied to opposite sides of a tier of such stones. In the present invention, the stones on a flat pallet are contacted with side pressure to bring the stones into a compact unit on the pallet. While the stones are so clamped, the pallet is clamped along its opposite side edges and transported, with the tier of stones thereon, to a location above a previously deposited tier of such stones or a pallet. When so positioned, the pallet is withdrawn from its supporting position beneath the stones and the stones settle gently onto the previously laid tier or pallet. The force applied to the stones on the pallet is chosen to be less than the force that would be required to urge the stones against one another to form a self-supporting unit.
