A seamless elastic trim having improved elasticity and elastic recovery is disclosed. 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. |
