摘要 |
Method for producing a multi-ply web of flexible material, such as paper and nonwoven material and a multi-ply product produced according to the method. A first pattern roll, having a three dimensional pattern of alternating raised and recessed portions transfers glue to a first web shaped flexible material in a first press nip in glue sites covering an area corresponding to between 0.03 and 9% of the total area of the first web material and sparsely distributed over substantially the entire area of the first web material. A second web shaped flexible material is brought in contact with the glue applied side of the first web material in a second press nip between a second pattern roll having a three-dimensional pattern corresponding to that of the first pattern roll, and an impression roll. The first and second pattern rolls are driven in registry.
