  • Patent number: 4190478
    Abstract: A process and an apparatus for producing faced or laminated sheets, wherein a carrier web is provided and covering sheets are adhesively attached to the carrier web and the carrier web is then divided into individual faced sections. The carrier web is provided with spaced apart, transversely extending lines of perforations. The carrier web is an endless sheet of corrugated paper and adhesive is applied to the crested side of the corrugated paper. The covering sheets are mounted on the carrier web such that when the carrier web is torn along a line of perforations, at least one of the leading and trailing edges of the respective covering sheet for the torn off section of the carrier web projects beyond the adjacent line of perforations at the end of the torn off section of the carrier web. The covering sheets are either individual sheets or a continuous web which itself is provided with lines of perforations extending transversely across the covering sheet web.
