ABSTRACT:
A plurality of supporting elements for providing a separation between adjacent casting molds are interconnected by a web or band. The interconnecting element allows the supporting elements to be easily placed on a mold surface, and requires securing only selected ones of the supporting elements to the mold surface. The remainder of the supporting elements are held in place by the action of the interconnecting element.
