    Abstract: A furniture frame part or the like is made from a first, planar laminate of wood or other material. This laminate is bent so as to form a shaped member of single curvature. The shaped member is cut into slices in a direction transverse to the generatrices of the curvature, and from these slices a second laminate is made. This second laminate is bent in a direction so as to form another curvature with generatrices extending generally transversely to the first mentioned generatrices, whereby a furniture frame part or another composite body of double curvature may be made.
