Abstract

A process and apparatus for producing a laminate containing a metal foil strip and a plastic film strip, in which the two strips have stamped structures repeated at regular intervals in the longitudinal direction of the strips and are disposed at contiguous points in the laminate, a pre-stamped strip and the second strip being continuously joined together from one end. To laminate stamped plastic film tape together with a pre-stamped metal foil tape, with the least possible complexity, so that any mismatch between the stamped structures of the two tapes is as small as possible, after the strips have been merged, the position of position markings for the stamped structures in the second strip and on the pre-stamped strip are successively scanned and, once a predetermined position of the position markings has been reached, a stamped structure is introduced into that region of the second strip situated in front of the site of the joining together, at a distance from the predetermined position corresponding to an integral multiple of the interval at which the stamped structures of the pre-stamped metal strip are repeated.
