Abstract
A screed assembly is provided for a paving vehicle for forming a mat of paving material upon a base surface, the vehicle having a longitudinal centerline. The screed assembly includes a frame connectable with the vehicle and a first screed plate movably connected with the frame and rotatable about a first axis extending perpendicular to the vehicle centerline. A second screed plate is movably connected with the first screed plate and is rotatable about a second axis extending perpendicular to the first axis. Further, a connective member has a first end connected with the frame and a second end linearly displaceable with respect to the first end and pivotably connected with the second screed plate. When the first plate displaces about the first axis, the second plate pivotably displaces with respect to the connective member while the distance between the two ends of the connective member remains substantially constant.
