Abstract
A method of making a composite elastic laminate is provided where an elastic layer is stretched in the machine-direction and while in a stretched state is fed into a grooved-roll assembly, together with outer facing layers, for imparting simultaneous cross-direction stretching forces to the superposed layers. The bi-directional stretching forces causes the elastic layer to tear and/or rupture allowing the laminate to be bonded in areas where the elastic layer has been displaced. Upon relaxation, a composite elastic laminate is provided having excellent breathability and elastic properties.
