  • Patent number: 4099619
    Abstract: A tube of flexible strands, closed at one end, is bunched up over a hollow mandrel. A sheet of sorbent material is slit into a plurality of strips before being forced through the mandrel into the tube by pull rollers.The plurality of strips become folded in accordion pleats resembling ribbon candy having a large surface area as they are forced into the tube. As the tube becomes filled with strips it is forced off the mandrel. When full, the second end of the tube is closed. The finished, filled tube is useful as a sorbent for oil, especially oil on the surface of water. The buoyancy of the finished tube is varied by the inclusion of a buoyant strip.
