ABSTRACT:
A levee gate and the process for the production thereof. The levee gate of the invention includes a rectangular sheet of thermoplastic material with a rectangular sleeve located on one edge of the thermoplastic material, the rectangular sleeve being a portion of the rectangular sheet fused to the rectangular sheet. The process for the production of the levee gate includes extruding a cylindrical tube of thermoplastic material, inflating the cylindrical tube as it is extruded to provide an inflated length of tube, flattening the inflated length of tube without fusing the opposed walls of the tube to each other, and continuously fusing a portion of the opposed walls together to form a seam.
