Abstract A concrete wall forming apparatus is described that facilitates formation of an elongated concrete wall between opposed sheet forms. An assemblable frame mounts the sheet forms in upright opposed orientations. The frame supports pairs of driven rollers that move against external surfaces of the sheet forms along the length of the wall as concrete is being poured. Each pair of rollers is driven by a selectively removable drive assembly including a single motor drive and gear arrangement by which both rollers of the pair are driven simultaneously. At least one of the rollers is connected to the driving gears through a clutch arrangement. The clutch may be selectively operated to disengage the roller at the inside of a corner, thereby allowing that roller to remain stationary while the remaining roller rotates to move about the outward radius of the corner. The clutch can then be engaged so that continued operation of the motor will result in corresponding counter-rotation of both rollers and movement of the roller pair along the path beyond the corner.
