ABSTRACT:
A paving machine employs at least one gate mechanism which can selectively alter the weighting of the flow of paving materials from the discharge opening of a hopper by adjusting the contour of the effective lower edge of the gate mechanism. This contour is preferably adjusted by forming the gate mechanism from front and rear vertically adjustable gates, the lower edges of which have opposed tapers. The discharge of materials from the opening is weighted towards one side when the front gate is raised and the rear gate lowered or partially lowered, and is weighted towards the other side when the rear gate is raised and the front gate lowered or partially lowered. Discharge may be prevented altogether by fully lowering both gates.
