ABSTRACT:
In an apparatus for applying a cover foil to a bottom foil having a containment structure formed therein, the containment structure is formed into sections of the bottom foil in a molding tool through which the bottom foil is moved section-by-section. The bottom foil is then guided over an application roller which has depressions in which the containments formed into the bottom foil are received while a cover foil is applied to the bottom foil. The depressions in the application roller are arranged, in the circumferential direction of the application roller at a slightly larger distance from one another than the containments formed into the bottom foil so that the bottom foil is slightly stretched on the application roller. Means are provided for adjusting the lengths of the bottom foil section moved through the molding tool depending on the position of the cover foil relative to the bottom foil.
