ABSTRACT Methods, the products produced thereby, and apparatus for forming conformable garments having selected discrete elasticized areas More specifically, methods and apparatus for stretching one or more ribbons of thermoplastic elastomeric material, immobilizing the stretched material in its extended state, subjecting spaced discrete areas of the stretched material to heat so as to "kill" the elastic properties thereof in the heated regions while leaving the elastic properties of the intermediate unheated regions thereof unaltered, and bonding the alternate elasticized and non-elasticized zones of the elastic ribbon to a continuous web suitable for use in forming a plurality of interconnected, but severable, like conformable garments having selected discrete elasticized areas on a high speed production basis. In the preferred form of the invention, the conformable garment thus formed comprises a disposable diaper product.
