Abstract
A laminated threaded rod comprises a number of pressed and glued together laminated sections extending longitudinally of the rod. The laminations of all of the sections extend substantially perpendicularly to the superficies of the rod at least at four different locations on the superficies and which are opposed to each other cross-wise within a cross-sectional plane of the rod. The glued together laminated sections can have various initial cross-sections prior to being machined into rounded threaded form such as triangular or rectangular, and the number of sections can also be varied, there being, for example, four or eight triangular sections or three rectangular sections.
