PROCESS FOR MANUFACTURING INDIVIDUAL LAYERED STRUCTURES COMPRISING PARTICULATE MATERIAL, AND LAYERED STRUCTURES THEREFROM

摘要

A process for manufacturing individual layered structures (12) and the individual layered structures (12) produced. There is provided a continuous web layered structure (14) having cutting lines across the widt h. The continuous web layered structure (14) contains particulate materials (6, 7, 9) between two containing layers (1, 2). One of the two containing layers (1, 2) is permeable to liquids. A thermoplastic material (16), in liquid form, is applied to the continuous web layered structure (14) over at least part of the cutting lines. The thermopalstic material (16) will join the two containing layers (1, 2) at each point of application. The thermoplastic material (16) is allowed to set. The continuous web layered structure (14) is cut along the cutting lines within the applied thermoplastic material (16) to provide individual layered structures (12).
