    • 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.
    • 本发明涉及一种用于生产通常用于汽车中的可调节转向柱的类型的薄片包装(60,70)的方法,该方法包括由软金属片材料制成的软片(71)和至少一层分层硬片(71 )放置在所述材料的顶部。 薄片(71,74)由至少一个由软片(71)制成的铆钉连接。 该方法的特征在于使用一个接一个地定位的压力机(110,120)。 柔性薄片(71)以由压机(110)指定的速率从第一压机(110)中的所述较软材料的条带(111)形成并冲压。 在该物质中产生的软片(71)被运送到第二压机(120)。 至少一个硬片(72,74)在来自较硬片材的带(121)的第二压制(120)中完全形成,然后冲压。 将所述硬片放置在软片(71)上并产生铆钉连接。
