Abstract

The invention relates to a method for producing data carriers containing a positioned element on at least one of their surfaces from a multiple-copy sheet. As many method steps as possible are performed on the multiple-copy sheet which is subdivided, before the elements are positioned in the data carriers, into smaller units having positioning markings as position references. Using these markings the small units are brought in an exact position relative to various working stations, where several data carriers in the units are provided with a positioned element simultaneously.
