ABSTRACT:
A method and apparatus for manufacturing a garment which is three dimensionally molded. The garment in the form of opposing sheets of fabric are fed from bolts of fabric to a molding station wherein a male mold section is provided in the shape of the three dimensional garment desired. A pair of opposing female mold sections close onto the male mold section sandwiching the sheets of fabric into the mold cavities. Heat is applied to mold the fabric sheets into the three dimensional garment. Simultaneously, an ultrasonic seamer cuts and bonds the periphery of the material around the mold. The mold cavity is then opened, portions of the mold are separated and the garment is then lifted off the male mold section.
