ABSTRACT:
An apparatus for continuously shaping and extruding concrete or other moldable material as a decorative curbing. The apparatus is operable by one person at high extrusion velocity, negotiates short radius serpentine curbing paths, and is maneuverable in tight spaces because of side-to-side and vertical adjustment features, and a short "wheel base". Moldable material is placed in a hopper and flows into an auger which compresses, mixes and extrudes the material through a shaped, non-flanged mold into the desired curb bed. A fueled engine or electric motor drives a hydraulic pump to pressurize hydraulic fluid. The pressurized fluid drives a hydraulic motor which turns the auger. The speed is controlled by simply setting a fluid flow valve.
