<p>A method of making a beam (18) includes:- a) providing a nail-plate-applying station, b) positioning a pair of lengths of timber (16 & 17) in spaced parallel relationship, c) advancing the pair of lengths of timber (16 & 17) incrementally relative to the nail-plate-applying station, and d) attaching a nail plate (10) to each side of the pair of lengths of timber (16 & 17) at each of a plurality of spaced positions along the pair of lengths of timber (16 & 17) so as to join the two lengths of timber (16 & 17) together to form the beam (18). <IMAGE></p> |
