Abstract
An apparatus for continuously shaping and extruding a longitudinally extending curb of moldable material. The device provides a self-contained and self-powered platform for modular curb forming inserts of multiple disciplines including auger extrusion and vibratory slip form. Moldable material is supplied to a feed hopper for the modular auger/slip form inserts that creates and dispenses a shaped curb bed. Leveling sensors and guides compensate for irregular surface gradients maintaining the orientation of the formed curb shape.
