ABSTRACT:
Methods and apparatus for assembling a contraceptive device made up of a rolled condom having an open end having a ring and a closed end having thereon a ribbed, inverted reservoir, with a pair of strips rolled into the condom on opposite sides thereof for unrolling the condom onto the penis. The condom in unrolled condition is placed on an elongated form and the ends of the strips are brought into contact with the condom and held there by streams of air. A pair of elongated rolling elements are brought into contact with the condom ring and moved in a direction parallel to the form to roll the condom and strips, the preferred rolling elements being in the form of a tube coaxial with the form. The form is provided with a recess in the end thereof for receiving the reservoir when a vacuum is applied to the recess. Intermediate portions of the strips are moved toward each other and held there as two heat-sealable packaging sheets are moved together on opposite sides of the condom, the free ends of the strips extending in opposite directions from the condom. Heat and pressure are applied to the packaging sheets around the edges thereof to seal the packaging sheets together to form a package, the ends of the strips being sealed to opposite sides of the package.
