Wound dressing and method for manufacturing the same
First Claim
1. A method for producing a wound dressing, comprising the steps of:
- extruding a curable silicone mixture onto a continuously moving molding surface extending in a planar direction, the silicone mixture defining a first surface contiguous with the molding surface and a second surface opposite the first surface;
heating the molding surface at a curing temperature sufficient to cause the silicone mixture to cross-link;
uniformly spreading the silicone mixture over the molding surface such that the silicone mixture has a generally uniform thickness and the second surface is substantially planar; and
laminating the second surface of the silicone mixture to an absorbent material after the silicone mixture has started to cross-link and transform to a gel due to exposure to the heated molding surface.

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