ABSTRACT:
The invention is directed to a web which has a plurality of parts extending in the longitudinal direction of the web and placed against each other. These parts may be stamped sheet metal parts or cast parts, which can be produced in a very cost-effective manner. Two outer parts can form a shell, into which a stamped interior part of steel has been inserted. These two parts can be produced cost-effectively as cast parts, for example of zinc, aluminum or a plastic material, and the interior part (12) can be produced as a stamped sheet metal part. The invention permits a particularly cost-effective production of the web and in bending tests was shown to be particularly stable.
