The device carries a curb forming shoe with a hopper thereabove slidable in relation to the shoe and communicating therewith in one position and closed with respect thereto in another. A ram is attached to a wall of the hopper and is movable toward and away from the shoe. Movement of the ram and the hopper permits asphaltic or portland cement mix to fall by gravity into the shoe and the compaction of the same in the shoe when the ram moves toward the same. The reaction force moves the curb forming machine away from the newly extruded curbing.,下面是Curb forming machine专利的具体信息内容。
