Abstract
Method and apparatus for providing a hollow, elongated construction element, for example for use as a vehicle front axle. The method includes (1) directing a first blank through a furnace (2) for heating the blank to a working temperature. The blank is directed between a pair of rollers (3, 4) having profiled surfaces, the blank being preformed in one or more steps to form an intermediate product having a predetermined profile along its longitudinal extent. The blank is fed to a forging press having a number of cooperating die pads, the blank being worked in a plurality of steps (5, 8, 11) to form a substantially finished product, having a cross section substantially in the form of a hat profile of predetermined varying height, width and material thickness along its length. A second blank (14), having essentially the same profile as the hat profile of the first blank in the dividing plane of the cooperating die pads, is placed in connection with the hat profile. In a later step (15), the first (1) and the second blank (14) are joined together, at least along their respective edges, to form a composite hollow construction element (18). One embodiment of the disclosed invention is also the construction element that is produced according to the above-described method.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
