ABSTRACT:
There is disclosed a method and apparatus for making bladders filled with a high viscosity fluid or gel. An elastic film is placed over a cavity formed in a first mold half and vacuum drawn into the shape of the cavity. A quantity of fluid is then deposited on the first film in the cavity and the first film and fluid are overlaid with a second film. The second mold half is placed in register with the first mold half to mate opposed sealing surfaces along an outer perimeter of the cavity. The vacuum is released to expel air from the cavity between the first and second films through channels corresponding to transverse grooves formed in the sealing surface of the first mold half. The first and second films are then welded at the sealing surfaces to form a sealed bladder filled with the fluid, and the fluid-filled bladder is removed from the mold halves.
