Abstract: A method is devised for continuous fabrication of thin membrane gloved enclosures in which a folded membrane ribbon is closed along the opposed longitudinal edges by a reversible closure comprising an interlocking set of beads. The ribbon is then repetitively stamped by a heated filament in the shape of a joined string of gloved enclosure and the interlocked beads are then separated, folded over to overlie the gaps formed and a second severing operation then parts the individual enclosures. In this manner a cuff is formed that can then be extended on top of an article grasped.
