ABSTRACT:
A method for fabricating a conical seamless bra pad preform for subsequent molding into a finished pad. The material used is fiberfill or the like and a blank, cut from such a sheet, or from a sandwich of two sheets, and is indented by a conical member which has pins spaced over the surface of the cone for engaging the material. Variable thinning of the material is achieved by the action of the pins in engaging the material successively. A second embodiment involves a series of coaxial rings to grasp the blank. Non-uniform displacement of the ringsets causes the desired uneven stretching of the blank.
