Method for joining fabric panels and manufacturing brassieres
A method of manufacturing a breast cup of a brassiere may include the steps of providing a pad including a first edge portion and a second edge portion, providing a fabric cover including a third edge portion and a fourth edge portion, superimposing the first and third edge portions, connecting the superimposed first and third edge portions together, superimposing the second and fourth edge portions, connecting the superimposed second and fourth edge portions together, ultrasonically cutting and fusing the connected first and third edge portions to form a first line of fusion joining the pad and the fabric cover, ultrasonically cutting and fusing the connected second and fourth edge portions to form a second line of fusion joining the pad and the fabric cover, and turning the joined pad and fabric cover inside out along the first and second lines of fusion to form seamless edges.
1. A breast cup, comprising:
a cup-shaped pad;
a fabric cover, and
a stitchless edge,
wherein said stitchless edge comprises a line of fusion along an edge of said pad where said edge of said pad is fused to an edge of said fabric cover, and
wherein said line of fusion includes a stabilizing strip attached to said pad by an adhesive film provided on one side of said stabilizing strip, said edge of said pad being positioned between said stabilizing strip and said edge of said fabric cover when said edge of said pad is fused to an edge of said fabric cover.
2. The breast cup of claim 1 , wherein said pad has an inner breast-receiving surface.
3. The breast cup of claim 2 , wherein said inner breast-receiving surface comprises a thermoplastic material.
4. The breast cup of claim 1 , wherein said pad is made of a material selected from the group consisting of nylon, polyester, spandex, foam and combinations thereof.
5. The breast cup of claim 1 , wherein said fabric cover comprises an elastic material that includes nylon, polyester, spandex and combinations thereof.
6. The breast cup of claim 1 , wherein said stabilizing strip is made of nylon.
7. A brassiere, comprising:
two of the breast cups of claim 1 , wherein each of the two breast cups are affixed to each other,
a back band, wherein each of the two breast cups are affixed to the back band, and
two shoulder straps, wherein each of the two breast cups are affixed to a respective one of the two shoulder straps.
8. A breast cup, comprising:
a cup-shaped pad;
a fabric cover attached to said pad along a line of fusion, the line of fusion provided along an edge of said pad where said edge of said pad is fused to an edge of said fabric cover;
wherein the fabric cover attached to the pad is turned inside out along the line of fusion to form a breast cup,
wherein said line of fusion includes a stabilizing strip attached to said pad by an adhesive film provided on one side of said stabilizing strip, said edge of said pad being positioned between said stabilizing strip and said edge of said fabric cover when said edge of said pad is fused to said edge of said fabric cover.
9. The breast cup of claim 8 , wherein said pad has an inner breast-receiving layer.
10. The breast cup of claim 9 , wherein said inner breast-receiving layer is made from a thermoplastic material.
11. The breast cup of claim 8 , wherein said pad is made of a material selected from the group consisting of nylon, polyester, spandex, foam and combinations thereof.
12. The breast cup of claim 8 , wherein said fabric cover comprises a material selected from the group consisting of nylon, polyester, spandex and combinations thereof.
13. The breast cup of claim 8 , wherein said stabilizing strip is made of nylon.
14. A brassiere, comprising:
two of the breast cups of claim 8 , wherein each of the two breast cups are affixed to each other,
a back band, wherein each of the two breast cups are affixed to the back band, and
two shoulder straps, wherein each of the two breast cups are affixed to a respective one of the two shoulder straps.
15. The breast cup of claim 1 , wherein said stitchless edge comprises a stitchless connection of said pad to said fabric cover.
16. The breast cup of claim 15 , wherein said stitchless edge comprises an edge formed by turning the fabric cover attached to the pad inside out along the line of fusion.
17. A breast cup of a brassiere formed by a method comprising the steps of:
providing a cup-shaped first fabric panel and a second fabric panel;
overlapping said first and second fabric panels to form a superimposed peripheral portion;
connecting said first and second fabric panels together by stitching the first and second fabric panels together to form a line of stitching at said superimposed peripheral portion;
ultrasonically cutting and thereby fusing the connected first and second fabric panels at said superimposed peripheral portion to form a line of fusion joining said first and second fabric panels and thereby removing the line of stitching; and
turning said joined first and second fabric panels inside out along said line of fusion to form a breast cup,
wherein said line of fusion includes a stabilizing strip attached to said first fabric panel by an adhesive film provided on one side of said stabilizing strip, said first fabric panel being positioned between said stabilizing strip and said second fabric panel when said superimposed peripheral portion of the connected first and second fabric panels are fused.
