A simplified elastic laminate is made from nonwovens and is especially suitable for side panels of training pant garments or the like. A plurality of thermoplastic adhesive elastomeric fibers are located between first and second facing webs. The fibers have an elastic core and adhesive surfaces. The facing webs, with the elastomeric fibers between them, are calendered together thus adhering the facing webs together via contact adhesion with the elastomeric fibers.

Elastic strand bonded laminate

A targeted elastic laminate material is provided having at least one low tension zone with first filaments having a first basis weight and at least one high tension zone having second filaments with a second basis weight greater than the first basis weight. The second basis weight is greater due to increased average thickness of the second filaments and/or increased frequency of second filaments relative to the first filaments. Methods and modifications of those methods are provided to produce a targeted elastic laminate material according to the preferred embodiments of this invention.

Targeted elastic laminate having zones of different basis weights

A method for ultrasonically bonding thermoplastic materials, for example melt-compatible thermoplastic materials, wherein the thermoplastic materials are preheated prior to entering an ultrasonic bonding means, thereby substantially increasing an ultimate bond strength established between the materials during the ultrasonic bonding process.
