    摘要： A method and apparatus for forming a tensioned garter and bonding it to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surface. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim. An ultrasonic horn seals a garter flange to a substrate where they are supported by the mandrel rim. The mandrel rim is shaped to provide a continuous seal which is weakened at its inner edge. When the weakened edge is broken, substrate and garter materials inside the seal edge are removed, thereby forming a hole around which the remaining portion of the garter may contract. Vacuum is applied from the mandrel top surface to the substrate inside the garter in this embodiment in order to break the seal edge and remove this material as the substrate and garter are stripped off the mandrel.

    摘要： Non-perforated tear lines for removal and evacuation of contents of disposable undergarments such as training pants. Non-perforated tear lines include a series of bond sites which are shaped, sized, spaced and arranged to provide a zone of weakness to permit severance of nonelasticized portions as well as elastic disposed in the waistband, the body of the pant, and the elastic leg bands for complete removal. Bond sites are formed by displacing a portion of material such that a thickened outer edge defines a weakened area of reduced thickness. Thus, elastic in the waistband may be disposed continuously 360 degrees around the wearer's waist, and elastic in the leg bands may be disposed continuously 360 degrees around the wearer's legs. In addition, improved pants having elasticized ear flaps in the body of the pants can be conveniently removed from the wearer. The shape, size, spacing and arrangement of the individual bond sites is determined for each material used in order to permit severance of the particular material while preventing premature removal. Because the tear lines of this invention are capable of separating elastic, location of the tear lines is not limited to side seams, but may be placed on the front of the pants for convenience.
