MANUFACTURING PROCESS OF INDIVIDUAL LAMINATED STRUCTURES CONTAINING PARTICULATE MATERIAL AND LAMINATED STRUCTURES OBTAINED THEREFROM

摘要

A process for manufacturing individual layered structures (14) comprising the steps of: a) providing a continuous web-like layered structure having designated cutting regions and comprising a particulate material (6,9) between containing layers, at least one of the layers being permeable to liquids; the process further comprises the steps of: b) applying a thermoplastic material in liquid form to the continuous web-like layered structure over at least part of the designated cutting regions, so that the thermoplastic material joins the containing layers where it is applied, c) allowing the thermoplastic material to set, and d) cutting the continuous web-like layered structure in the designated cutting regions to provide the individual layered structures (14). An individual layered structure (14) obtainable with this process is also described.
