Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A method of preforming seamless brassiere pads fabricated from sheet fibrous batting material which comprises: a. clamping said sheet of fibrous batting material at the periphery of said pad; and b. driving a substantially conical member into said sheet, said conical member having a plurality of pins extending from the surface of said member and aligned in the direction of motion of said member said pins being distributed over substantially all of the surface of said member with the exception of an area surrounding the apex of said member whereby when said conical member is driven into said sheet, a predetermined amount of stretch will be imparted to said sheet in the region of said sheet in contact with the apex portion of said member and stretching of the remainder of said sheet will be progressively arrested as said pins progressively engage said sheet.
Claim 2
Independent Claim
144 words
A method of preforming seamless brassiere pads fabricated from sheet fibrous batting material which comprises: a. clamping said sheet of fibrous batting material at the periphery of said pad; and b. driving a substantially conical member into said sheet, said conical member having a plurality of pins extending from the surface of said member and aligned in the direction of motion of said member said pins being distributed over substantially all of the surface of said member with the exception of an area surrounding the apex of said member whereby when said conical member is driven into said sheet, a predetermined amount of stretch will be imparted to said sheet in the region of said sheet in contact with the apex portion of said member and stretching of the remainder of said sheet will be progressively arrested as said pins progressively engage said sheet.
Claim 3
Dependent Claim
32 words
The method of claim 1 and further including the step of applying acrylic resin to said sheet of fibrous batting material either prior to the clamping and driving steps or subsequent thereto.
Claim 4
Dependent Claim
35 words
The method of claim 1 where said pins are distributed over substantially all of the surface of said conical member whereby the stretching of said sheet will be progressively arrested upon engagement with said pins.
Claim 5
Dependent Claim
45 words
The method of claim 1 where the closest of said pins to said apex form a substantially circular pattern around said apex whereby a predetermined amount of stretch will be imparted to said sheet at said apex upon driving said conical member into said sheet.
Claim 6
Dependent Claim
46 words
The method of claim 1 where said pins disposed farther from the apex of said conical member are spaced generally farther apart whereby areas of said sheet contacting pins more remote from said apex will be stretched more upon driving said conical member into said sheet.
Claim 7
Dependent Claim
29 words
The method of claim 1 where said pins are spaced farther apart over areas of said conical member corresponding to areas of said pad where greater stretching is desired.
Claim 8
Dependent Claim
28 words
The method of claim 1 where said sheet is clamped between a pair of rings, said rings being forced together by the action of a fluid driven piston.
