PCT No. PCT/FI91/00104 Sec. 371 Date Sep. 14, 1993 Sec. 102(e) Date Sep. 14, 1993 PCT Filed Apr. 9, 1991 PCT Pub. No. WO92/18719 PCT Pub. Date Oct. 29, 1992.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. |
