<p>A method for production of a trussed rafter, where the nail plates are fixed to timber members at cutting before they are brought to the assembly station. The assembly station can be any type of a rafter jig but it can also be a levelled surface, e.g. a factory floor, whereby an assembly jig is not needed at all, the labor and force required for timber member jointing are minor, because the nail plates are already fixed to the timber members and assembly can take place completely or at least to the main part by means of upper plates (8). The assembly surface has a mesh pattern (1), by means of which side guides (2) needed at assembling can be positionned. Markings indicating prefixed platings and/or nail plate positions are used in quality control.</p> |
