Abstract
The invention relates to a method for producing lamella packets (e.g.) such as those used for adjustable steering columns in automobiles. According to the invention, at least one of the lamellae (e.g.) is provided with a collar () and is joined to another lamella (e.g.) so that the collar () of the first lamella () is supported against the other lamella () whereby defining the width (B) of a space between the lamellae (). Both lamellae () are welded at at least one location of the collar (). The welding is preferably carried out by resistance welding. In order to obtain defined ratios, the edge of the lamella collar () is preferably provided with projecting points (Z). The method is, among other things, advantageous in that the same material quality can be used for all lamellae ().
