CORE ELEMENT FASTENING AND ASSEMBLY METHOD

摘要

Core sand elements are rapidly and reliably retained in an assembly by drivi ng one or more smooth surface fasteners, such as staples, nails or brads, into the cor e elements. Such an assembly method comprises positioning at least two core elements in a cor e assembly, positioning a smooth surface fastener for entry into the at least two core elements, and driving the smooth surface fastener into the two core elements to fasten them in the core assembly. In such a preferred method, the smooth surface fastener comprises a staple with two smooth surface tines connected by a crown and the staple is positioned for entry of one tine into each of two core elements with the crown of the staple spanning the interface between the two core elements.
