    Abstract: The invention relates to a method and an apparatus for jointing members made of plastic-coated paper or board. In accordance with the invention, the sealable members are retained in position with clamps and sealing is performed with a laser sealing means moving along the sealing line, a means for opening the seal point pressing the members apart to continue keeping the seal point open, a laser beam being directed to the open seal point for melting the coating plastic and a means for closing the seal pressing finally the members against each other, the plastic jointing the members when solidified. The method is applicable to lateral sealing of bag or container packages formed of blanks, among other things.

    Abstract: The invention comprises a method for producing identification marks (5) on layer-structured paper or board (7) to be manufactured in a continuous web a nd the marked papers and boards obtained with this method. With this method, th e marks (5) are made with a laser beam on a moving web form fiber layer (1), o n which a second layer of material (6) is subsequently overlaid in such a way that the marks remain inside the layer-structure of the moving web. The seco nd material layer (6) may comprise a second fiber layer or, for example, a polymer coating. The laser marking could take place, for example, by burning the surface of the fiber layer (1) or by engraving it. Inside the layer structure, the marks (5) are protected, but detectable with a detector to ensure the authenticity of the material: The marked paper or board is suitab le for product packages to be protected against product forgeries.
