ABSTRACT:
This machine consists primarily of a frame, which is supported by wheels, and the frame supports three spaced-apart self-placing form units, which operate in conjunction with finishing rollers. The self-placing form units of the machine are faced with endless synthetic rubber belts, which are backed up by hinged steel pads, and the top and bottom of the self-placing form units are sealed with a plate having a lip at the edge, to overlap the synthetic rubber, so as to repel any foreign matter, or concrete mix, from entering the inside of the units. The machine is reversible in direction when desired, and is used for concrete curb and gutter construction.
