The trim preferably comprises a cut edge, an elastic band, and a peripheral section of a fabric material folded over upon itself to form a substantially flat hollow structure for enclosing the elastic band. An adhesive layer is disposed on one side of the elastic band, and the elastic band is attached to a surface of the hollow structure by thermal or ultrasonic bonding, or by any suitable bonding material or technique. The elastic band may be provided continuously, or at predetermined intervals within the hollow structure. Likewise, the adhesive layer may cover the entire length of the elastic band, or the coverage may be confined to fixed intervals. A method and apparatus for fabricating the seamless elastic trim of the present invention along the periphery of a material are also disclosed.

BONDING ELASTIC TO FABRIC OF A GARIUIENT
FIELD AND BACKGRO[JND OF THE INVENTION
[00011 Throughoutthis appiication, various references are cited to describe the state and content of the art. Those disclosures, in their entireties, are hereby fncorporated into this application by reference.
[0002] The present invention relates generally to a seamless elastic trim or finished edges of a garment having improved elasticity and eEastic recovery.
The present invention afso relates to a method of making such seamless elastic trim or finished edges along the periphery of a garment.
The present invention afso relates to a method of making such seamless elastic trim or finished edges along the periphery of a garment.
[0003] Seamless trims have been provided on garments, such as bras, underv+-ear, swimwear, camisole, diapers, and articles of c{othing worn directly next to the skin,. to enhance the user's comfort while wearing the garment.
Seamfess trims provide the garment with an aesthetically pleasing look while preventing the garment from fraying at the periphery. Frequently, it is desirabfe to have the trim conform with the contours of the body, such as for providing greater support or better anatomical fit. This is achieved by forming the trim with an elastic insert.
Seamfess trims provide the garment with an aesthetically pleasing look while preventing the garment from fraying at the periphery. Frequently, it is desirabfe to have the trim conform with the contours of the body, such as for providing greater support or better anatomical fit. This is achieved by forming the trim with an elastic insert.
[0004] Formation of elastic seamless trims is typically accomplished by providing an adhesive layer on both sides of the elastic insert, enclosing the elastic insert within the trim, and melding the adhesive layers with the elastic insert and trim by thermal or ultrasonic welding, See, e.g., Cano, U.S. Patent Application Publication No. US 2004/0238102. The resulting trim has solidified adhesives permeated through the elastic insert and garment, thereby reducing the elasticity and elastic recovery of the elastic insert, and giving the trim a stifferfeel. Elastic seamless trims are also produced by ultrasonically bonding the fabric to itself to create a tunnel along the fabric edge. The elastic band is, then inserted through the tunnel, but without attaching the elastic band to the walls of the tunnel. See, e.g., U.S. Patent 6,622,312 to Rabinowicz. The drawback of this type of trim is that a cyiindrical bulge along the edge of the trim may appearthrough the wearer's outerclothing. Alternatively, elastic seamless trims are produced by fusing thermplastic materials in the elastic insert and fabric. See, e.g., U.S. Application Publication No. US 2004/0106354 to Falla, et al. This method produces regions or pockets of hardened thermoplastic material which reduces the comfort level for the wearer.
[0005] Accordingly, a need remains for an elastic seamless trim that is capable of overcoming one or more of the above-mentioned disadvantages. It is contemplated that the formation of the elastic seamless trim of the present invention by thermal or ultrasonic welding does not reduce the level of comfort forthe wearer or impact the elasticity and elastic recovery of the fabric or elastic insert.

SUIVINlARY DF THE INVENTInN
[0007] It is an object of the present invention to provide the periphery or trim of a material, such as a fabric or bra in particular or a garment in general, with a smooth, finished edge and having a thin profile. V1lhen the finished edge is provided, for example, on the periphery of an item of underwear, i.e., a brassiere, it is fabricated such that the soft, satiny feel of the fabric and the flexibility and elastic recovery of the elastic band enclosed within the finished edge or trim is not affected. The finished edge preferably comprises a cut edge, an elastic band or cord, and a section of the material folded over upon itself and hemmed to form the finished edge. The folded section of the material defines a flat holfow structure for enclosing the elastic band or cord.

The method preferably comprises providing an elastic band or cord along the periphery of the material, aligning the elastic band or cord generally parallel with the edge of the material, disposing a heat activatable or curable adhesive layer on one side of the elastic band or cord, folding the periphery of the material to form a flat hollow structure for enclosing the elastic band or cord, attaching the elastic band or cord to the interior of the hollow structure, and hemming the opening of the hollow structure to form the finished edge. It is understood that the attaching and hemming operation can be carried out sequential[y or simultaneously. It is also understood that hemming can be effected by ultrasonic or thermal welding, or by a suitable bonding technique.
[0009] It is a further object of the present invention to provide an apparatus for fabricating the finished edge as described above along the periphery of a material.

arranging said elastic member between said first and second part;
joining said elastic member to the inner surface of said hollow structure; and attaching said cut edge of said first part to said second part.
19. The method of claim 18, wherein the joining and attaching step is performed concurrently or sequentially.
20. A method of claim 18, wherein the width of said first and second part is at least the width of said elastic member.
21. An apparatus for fabricating the edge trim of claim 1 along the periphery of a material, comprising:
a dispenser for storing and dispensing an elongated elastic band having an adhesive layer disposed continuously, or at uniformly spaced intervals, along only one side of said elastic band;
a work surface configured to guide and support said section;
an aligning element configured to maintain said elastic band over said section at an appropriate position and orientation;
said elastic band being positioned by said aligning element over the area of the section forming said second part, and oriented in parallel with said second part;
a folding element configured to fold said section upon itself along a line extending between said first and second part, as said material and elastic band is moved across said work surface; and a joining element configured to simultaneously attach said elastic band with said first or second part, and to attach said first apart about said cut edge to said second part, wherein said operational elements are arranged and configured to provide the periphery of said material with said edge trim in a continuous manner, or at predetermined intervals.
22. The apparatus of claim 21, wherein said joining element comprises a thermal or ultrasonic welding unit.
23. The apparatus of claim 21, further comprising a controller adapted to automate said apparatus, wherein said controller comprises a memory, a firmware, a program, a data storage unit, and a processor connected to a signal interface, wherein said signal interface is adapted to transmit control signals to and to receive or process feedback signals from said operational elements of said apparatus.
