The method may further include the use of a plastic overlay on the fresh concrete prior to imprinting so as to provide a well rounded edge to the formed stones. A number of tools for forming the nonrepeating patterns are also disclosed. One of such tools is a walking tool including a flat platform having a plurality of apertures, a shaft rotatably extended through each aperture, a hub on each shaft below the platform on which the platform rests, a flange on each shaft engaging the top of the platform, a plurality of imprinting blades extending from each hub to form a group, the top of each shaft having an anvil head to be pounded, and at least one of said apertures being elongated to render one group of blades both rotatably and laterally adjustable for varying the stone patterns to be imprinted in fresh concrete. Other tools suitable for use with the method include an individual group of blades arranged in the form of the corners of the stone to be imprinted, together with a striking area by which the blades can be pounded into the surface of the fresh concrete.,下面是Method for imprinting non-repeating stone patterns in fresh concrete专利的具体信息内容。
