Claims
- 1. An apparatus for producing a laminate of two strips comprising a metal foil strip and a plastic film strip, each strip in the laminate having longitudinally spaced stamped structures which are repeated at regular intervals along the length thereof and wherein the stamped structures are disposed at contiguous points in the laminate, which apparatus comprises:
- means for feeding and guiding a first one of said strips in a feeding direction, said first strip having said stamped structures therein and being provided with spaced position markings each corresponding to one, or a transversely extending row, of said stamped structures therein;
- means for feeding and guiding a second one of said strips in said feeding direction, said second strip having spaced position markings at positions corresponding to at least some of said position markings on said first strip;
- means for merging said first and second strip together so that one is on top of the other;
- scanning means for detecting the position markings on said first strip and said second strip, the scanning means having means for longitudinally adjusting said strips to place said position markings of said strips in coincidence; and
- a stamping tool positioned before said merging means and upstream of the scanning means at a distance which is an integral multiple of said intervals of the stamped structures, the stamping tool stamping stamped structures on said second strip corresponding to the stamped structures on the first strip after said scanning means has placed said strips in coincidence.
- 2. The apparatus of claim 1, wherein the first strip is the metal foil strip and the second strip is the plastic film strip.
- 3. The apparatus of claim 2, wherein the stamping tool also stamps the position markings on the plastic film strip.
- 4. The apparatus of claim 1, including bonding means downstream of the scanning means to bond the strips together and form the laminate.
- 5. The apparatus of claim 1, wherein the means for feeding the strips comprises a feeding device in the scanning means.
- 6. The apparatus of claim 1, wherein the stamping tool is adjustable in the feeding direction of said strips and transversely thereto.
- 7. The apparatus of claim 1, wherein the scanning means includes a spike as a scanning element.
- 8. The apparatus of claim 7, wherein the position markings are circular and the shape of the spike is matched to the shape of the markings.
