Patent ID: 7621694

Claim:
A method of forming longitudinally curved concrete curbing, said method comprising the steps: placing a single rotary curb-forming roller on a longitudinally curved form filled with wet concrete, wherein the form comprises a pair of laterally spaced, longitudinally extending, curved form members with one of the form members being shorter than the other form member, said roller including a cylindrical body, a smaller diameter neck at one end of the body, and a shaping surface extending between the body and the neck, said body and said neck being coaxial about an axis of rotation of the roller; positioning said roller on the form in such a manner that the cylindrical body of the roller rests upon the shorter one of the form members and the smaller diameter neck of the roller rests upon the taller one of the form members; pulling and steering said roller in a direction of advancement along the curved form, with the roller in engagement with the wet concrete as the body of the roller rides on the shorter one of the form members and the neck of the roller rides on the taller one of the form members; and driving said roller in such a direction of rotation while it is being pulled and steered along the form such that the lower periphery of the roller moves generally toward the direction of advancement to resist the pulling force and to shape and smooth the wet concrete into curbing.
