Abstract

The invention relates to a composite wooden beam and to a method for manufacturing the same. According to the invention, for maximum utilisation of the roundwood portion, the wooden beam is composed of a plurality of individual elements which enclose a hollow space 5 and the touching edge regions 8 of which each have the form of a truncated pyramid, so that by turning the respectively adjacent individual elements a wooden beam of constant cross-section can be produced from a conical roundwood portion, the systematic annual ring progression leading to a number of advantages. <IMAGE>
