US Patent 7227050 Method for producing a wound dressing

A method for making a wound dressing having an absorbent core and an elastomeric gel facing layer includes the steps of depositing uncured elastomeric gel onto a perforation device to form a discrete layer of elastomeric gel thereon, curing the elastomeric gel layer to a partially cured state and applying the absorbent core to a surface of the partially cured gel layer. The perforation device includes a generally planar surface with a plurality of discrete perforating elements extending therefrom wherein the perforating elements extend through the uncured elastomeric gel layer to form a plurality of apertures therein.
