  • Patent number: 4013750
    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.

  • Patent number: 3939023
    Abstract: A method of fabricating a brassiere pad which involves folding a fiberfill blank longitudinally, making an oblique cut at right angles to the fold through one thickness of the blank, folding the blank so as to expose surfaces which are to be bonded, refolding to abut the surfaces to be bonded and molding the resulting form to the desired pad contour. Means for controlling the thickness of the under portion of the pad to provide desired push up action is disclosed.
