Abstract: A die assembly for driving a pierce nut which comprises an annular coining portion provided on the top of a die body, the inner surface of the annular coining portion being continuous with a center aperture of the die body. An annular projection is provided at the upper portion of the center aperture for surely and temporarily holding punched debris in of the die body, near the annular coining portion, the center aperture. It is therefore possible to provide an inexpensive nut-driving die assembly with improved durability, and which can prevent debris, punched by shearing between a pierce nut and a metal panel and remaining at the upper portion of the center aperture, from being lifted up when the metal panel is lifted from the die body, thereby ensuring a continuous driving work.

Abstract: A method for production of a trussed rafter, wherein the nail plates are affixed to timber members in conjunction with cutting of the timber members and before they are transported to an assembly station. The assembly station can be any type of a rafter jig but can also be a levelled surface, e.g., a factory floor, thereby eliminating the need for an assembly jig. The labor and force required in timber member jointing are substantially reduced, because the nail plates are already affixed to the timber members and assembly can be largely limited to affixing of upper nail plates (8). The assembly surface has a grid pattern (1) thereon, enabling the positioning of side quides (2) required for assembling. Markings indicating prefixed platings and/or nail plates positions are used to provide quality control.
