In accordance with one aspect of the present invention, the apparatus includes a hinged foot roller assembly and a hydraulic cylinder for moving the assembly toward and away from the slab. A linear variable differential transformer signals the cylinder to move the assembly relative to the slab such contact between the foot rollers and the slab edge is maintained at a selected contact force. | |
