A method for producing a wound dressing wherein a curable silicone mixture (114) is extruded onto a generally planar molding surface (112). The silicone mixture (114) defines a first surface adjacent the molding surface (112) and a second surface opposite the first surface. The molding surface (112) is heated at a curing temperature sufficient to cause the silicone mixture (114) to cross-link. The silicone mixture (114) is uniformly spread over the molding surface (112) such that the silicone mixture has a generally uniform thickness and the second surface is substantially planar. The second surface of the silicone mixture (114) is laminated to an absorbent material (120) after the silicone mixture (114) has started to cross-link and transform to a gel due to exposure to the heated molding surface (112).

L'invention concerne un procédé de production de pansement consistant à extruder un mélange de silicone durcissable (114) sur une surface de moulage généralement plane (112). Le mélange de silicone (114) définit une première surface adjacente à la surface de moulage (112) et une deuxième surface opposée à la première surface. La surface de moulage (112) est chauffée à une température de durcissement suffisante pour entraîner la réticulation du mélange de silicone (114). Ledit mélange (114) est étalé uniformément sur la surface de moulage (112), de sorte qu'il présente une épaisseur généralement uniforme et que la deuxième surface soit sensiblement plane. La deuxième surface du mélange (114) est pelliculée sur un matériau absorbant (120) après que le mélange (114) a commencé à se réticuler et à se transformer en gel du fait de l'exposition à la surface de moulage chauffée (112).
