ABSTRACT:
A carrier matrix wound of a carrier strip having undulations in its transverse direction has deflections of the carrier strip, said deflections being arranged in planes. During the winding process, the deflections are created by the insertion of deflection pins between the corresponding winding layers. The deflections pins, in this case, are inserted between the winding layers as a function of the desired cross-section of the carrier matrix so that after the winding process and after the removal of the deflection pins, the carrier matrix can be inserted into a sheath that has the desired cross-section of the carrier matrix. By combining several winding bodies of this type into one carrier matrix, arbitrary cross-sections of carrier matrices can be produced, particularly cross-sections having concave archings. During the making process, the deflection pins are fitted through the corresponding bores of two winding disks that are connected with one another in a torsionally fixed way. The carrier matrix that is produced in this way can then be inserted into a sheath. This can be accomplished by a funnel-shaped arrangement.
