Claims2
A process for producing clothing comprised of:
- a. feeding a section of flattened thermoplastic tubing into a heated, two piece mold which is internally shaped in the form of the desired article of clothing so that a portion of the tubing is trapped and sealed off from the ambient air, drawing a vacuum between the walls of the mold and the tubing so that the tubing expands to conform to the internally shaped form of the mold and is permanently shaped into the desired article;
- b. relieving the vacuum, applying positive air pressure between the walls of the mold and the now-formed tubing so as to free it from the mold and opening the mold;
- c. drawing the sheet of tubing containing the formed article of clothing into a perforating press made up of a flat, moveable head containing needles arranged in a suitable pattern and a flat stationary bed containing holes corresponding to the position of said needles;
