ABSTRACT:
The invention is a jig for holding and positioning a flexible hollow article while being connected to another flexible hollow article. The jig includes a platen having a bottom surface and a die having a top surface. When the die and platen are positioned proximate each other, a cavity is formed in the die and platen. The cavity is sized and configured to accept the hollow flexible. One of the platen or die have formed therein a passageway in fluid communication with the cavity, whereby a vacuum may be applied to the outside surface of the article while in the cavity, whereby the shape of the hollow article is maintained.
