A process for producing multi-layer security products

The invention relates to a process for the production of multi-layer security products (11) consisting of at least one card (13) and at least one on at least one side of the card (13) applied polymer film which is provided on rolls and having at least one security feature (14), is provided, wherein a roller track of the polymer film (14) and at least one strip (18) with an n-times the number of benefits (12) are fed to a laminating station (31) and laminated before lamination a control line (23) on the polymer film (14) is interrogated, which is assigned to the at least applied one on the respective utility (12) security feature or the benefits (12) or the strip (18) associated with the reference mark (19) is extracted or the control line (23) and the reference mark (22) can be queried and a feed or feed or both of the roller conveyor of the polymer film (14) and the strip (18) for exa kth orientation are adapted to each other.
