Abstract
An elastic sheet-like composite comprising a multiplicity of elongate strands of resiliently elastic material, and one or more sheets of material bonded along its length or at sheet bonding locations to the elastic strands, some of which sheets have arcuate portions projecting from the elastic strands between those sheet bonding locations. The elastic sheet-like composite may be incorporated in disposable garments such as diapers or training pants. Also disclosed is a novel method and novel equipment for making the elastic sheet-like composite including in different combinations, sheet corrugating members, equipment for compacting the sheet along its length and an extruder that extrudes the strands onto the sheets and affords versatility in selecting characteristics of the elastic sheet-like composite to be produced without major modifications of the equipment.
