ABSTRACT:
A geometrically-shaped bag for lifting and positioning objects has a layer of fluid impermeable, non-porous material forming an expandable bladder having opposite ends and a first layer of wound strands enclosing the expandable bladder. A method of manufacturing the bag comprises the steps of providing a geometrically-shaped mold member having an axis of rotation extending through opposite ends of the mold member, coating the mold member with fluid impermeable, non-porous material to form an expandable bladder having opposite ends, winding a first layer of strands onto the mold member over the expandable bladder, and removing the mold member from the expandable bag.
