A device for smoothing a concrete paving surface including a machine frame that defines a predetermined working width perpendicular to a predetermined direction of travel of the machine frame, and a carriage system for moving the machine frame in the predetermined direction of travel. The device also includes a transverse smoothing portion carried by the machine frame for smoothing concrete paving across the predetermined working width that has two transverse structures with adjacent ends and remote ends and an articulating portion for connecting together the adjacent ends of the transverse structures. The device further includes a longitudinal smoothing portion for effecting longitudinal smoothing of concrete paving, and a moving portion for moving the longitudinal smoothing portion along the transverse structures over the entirety of the predetermined working width.
A device for smoothing a concrete paving surface comprising a machine frame defining a predetermined working width substantially perpendicular to a predetermined direction of travel, carriage means for moving said machine frame in the predetermined direction of travel, means carried by said machine frame for effecting transverse smoothing of concrete paving substantially across said predetermined working width, said transverse smoothing means including two transverse structures having relatively adjacent ends and remote ends, means for articulately connecting together said transverse structures adjacent ends, longitudinal smoothing means for effecting longitudinal smoothing of concrete paving, and means for moving said longitudinal smoothing means along said transverse structures over the substantial entirety of said predetermined working width.
