ABSTRACT:
A method and apparatus for manufacturing lined latex girdles in which one end of a fabric sheath which will form the liner of a latex girdle is sewn or otherwise held closed together and slipped over an annular rectangular frame, with the closed end of the bag disposed in the middle of the annular rectangular frame. A flat form, with curved sides, is first covered with a latex film, and while tacky, is pushed through the frame, engaging the fabric liner. As the form is pushed through the frame, the liner slides over the frame, and contacts the sides of the form. When the form has been pushed completely through the frame, the liner will be supported on the form, which may then be easily withdrawn for final processing. Close tolerances between the dimensions of the form and the frame assist in providing quality control with respect to the interpenetration of the fabric liner and the latex film.
