Abstract
A curb or other structure is formed by a moving slip form mold receiving material used to form the structure from a hopper. The slip form mold includes two portions pivotally connected to each other. In one configuration, the slip form mold portions form a straight structure and in another configuration they are employed to form a curved structure.
