ABSTRACT:
An auger/cut off assembly for a floating screed asphalt paver. The auger/cut off assembly consists of an auger mechanism with an axis of rotation and a cut off mechanism. The cut off mechanism has a concave cut off panel that rotates about the axis of the auger mechanism from an open strike off position to a closed cut off position. Because the concave cut off panel closely conforms to a portion of the circumference of the auger mechanism, the cut off mechanism provides for low ground clearance. The concave cut off panel serves the dual function of striking off the paving material when in the open strike off position and cutting off the deposit of paving material when in the closed cut off position.
