  • Patent number: 7923596
    Abstract: A method and system for producing an improved dressing product, useful for covering/protecting a moist wound is disclosed. The dressing product comprising fibers of a spinnable polymer forming a twisted ribbon. By virtue of this twisting, the fibers, in particular at the periphery of the ribbon, are connected to one another so as to afford better mechanical cohesion and a smoother outer appearance, without affecting the action of absorption, dilation and gel formation for extracting the biological fluid, nor the action of retention of proteins and other cellular and bacterial waste matter which would impede the phenomenon of cicatrization. The ribbon twisting equipment comprises a conical bowl (1) for driving fibers in rotation with a twisting die (3) in its narrowed downstream part (2), and a gear mechanism (4) for driving in rotation.
