Abstract: A roll of reinforcing wire mesh is mounted behind the last concrete hopper on the frame of a movable concrete plank-laying machine. The wire mesh is guided forwardly between an upper portion of the hopper and the lower end of a concrete-delivering chute so that the concrete passes through the wire mesh and into the hopper. A guiding plate connected to an upright wall of the hopper guides the wire mesh downwardly beneath the hopper where its direction is reversed so that it is laid on the concrete plank while concrete is discharged thereover from the hopper.
