Abstract
The invention relates to a method of producing plastic cards with a layer structure, in each of which cards a flat coil and a chip which is connected thereto are embedded, these components being placed on a first web, to which a subsequent web for accommodating apertures for the components and at least one covering web are applied, which webs are then joined together by lamination so as to form a final web, out of which plastic cards are stamped. In order to simplify such a method, it is envisaged that a second web, which is placed on the first web, is held on a selectable web section of the latter by means of fixing points, while an aperture which is to accommodate the flat coil is made in the second web, for which purpose the fixing points are distributed in such a manner that they are arranged on both sides next to a part of the web which corresponds to a shape of the flat coil, and then the flat coil, in order to be placed on the first web, is inserted into the aperture formed in this way and the chip is inserted into a web which is provided with a chip opening.
