Claim 8:
9. A method of manufacturing a flexible tank for the transport of bulk liquids or semi-liquid materials, comprising:
folding over the ends of rectangular shaped first and second layers of flexible polymeric material to form a continuous loop over the entirety of the width of said ends of said first and second layers;
connecting the longitudinal sides of the first and second layers to form an open ended tube;
attaching a first end of a first end flap to the inside of one of the first and second layers near a first end of the open ended tube and a first end of a second end flap to the inside of one of the first and second layers near a second end of the open ended tube, the length of the first end flap being greater than the distance from its point of attachment to the first end of the open ended tube and the length of the second end flap being greater than the distance from its point of attachment to the second end of the open ended tube;
cutting portions from each one of the continuous loops of said ends of said first and second layers so as to become a sequence of alternating hollow loops and spaces, the hollow loops and spaces of the first layer interlacing with the hollow loops and spaces of the second layer;
inserting an inner liner into the interior space of the open ended tube formed by connecting the longitudinal sides of the first and second layers, the inner liner made of a flexible water-proof polymeric material so as to enclose within it the bulk liquid or semi-liquid materials being transported;
moving the respective second ends of the first and second end flaps to cover the ends of the inner liner; and
closing the first and second ends of the flexible tank with the inner liner and end flaps constrained therein by threading a rope between the interlaced hollow loops of the first and second layers.
