    摘要: The invention relates to a method of hot laminating over distinct bond areas barrier and breathable layers (6', 6", 6"') made thermoplastic polymeric materials in order to form a multilayer (6) by way of a calender comprising a pair of counter-rotating cylinders (1, 2) with parallel axes, the mantle surfaces of which define a lamination gap (5) therebetween. On the surfaces of the mantles of both cylinders (1, 2) embossing patterns are formed, each embossing pattern comprising grooves (7, 8) defining therebetween continuous reliefs on the mantles of the two cylinders (1, 2), linearly extending at different or complementary angles of inclination with respect to the axes of the respective cylinders, as observable on an elevation view of the cylinders. During the lamination process the cylinders (1, 2) are heated at a temperature sufficient to soften the polymeric material of the layers pinched at crossovers of said continuous reliefs of the mantles of the two cylinders (1, 2) when the layers pass through said lamination gap (5), whereby bond zones are formed between adjacent layers (6', 6", 6"') at the crossovers of the continuous reliefs of the cylinder mantles.
