  • Patent number: 4834822
    Abstract: Of two edges (14, 16) to be joined together of a multilayer foil, the inner edge (16) is obliquely trimmed in the longitudinal direction prior to the pressing together in such a way that the layer (6) located remote from the surfaces (10, 12) to be pressed together protrudes beyond the other layers. If the two layers (14, 16) are pressed together during the welding operation by means of two tool elements, not shown, then the inner layer (6) of the inner edge (16) overflows so as to form one uninterrupted layer with the inner layer (6) of the outer edge (14). When the foil is used as packaging material, in particular as a tubular liner for a packaging tube, it is assured that the product to be packaged will come into contact only with the inner layer (6), so that an undesirable reaction with one of the other layers is avoided.
