发明名称 VERFAHREN ZUR HERSTELLUNG VON LAMELLENPAKETEN FÜR VERSTELLBARE LENKSÄULEN
摘要 The invention relates to a method for producing lamella packets (60, 70) of the type normally used in adjustable steering columns in automobiles and which comprise a soft lamella (71) made of soft sheet metal material and at least one layered hard lamella (71) placed on top of said material. The lamella (71, 74) are connected by at least one rivet made of soft lamella (71). The method is characterized by the use of presses (110, 120) positioned one after the other. A soft lamella (71) is formed and stamped out of a strip (111) of said softer material in the first press (110) at a rate dictated by the press (110). Soft lamella (71) produced in this matter are transported to the second press (120). At least one hard lamella (72, 74) is completely formed in a second press (120) from a band (121) of harder sheet material and then stamped. Said hard lamella is placed over a soft lamella (71) and a rivet connection is produced.
