working principle
A spiral blade is installed in front of the forming mold, and the blade rotates continuously to push materials such as cement or
asphalt concrete into the cavity of the mold. After filling the mold space, the concrete material will have a reaction force on
the spiral blade. When the reaction force is greater than the machine drive When the force is applied, the machine is driven
forward. When the machine is moving forward, the curbstone or water-stop that has been extruded will break away from the rear of
the equipment mold and remain on the working surface.
