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.

An elastic laminate is provided including outer facing layers of a fabric and, located between the outer facing layers, a series of individual, spaced apart strips of elastic film extending continuously along the direction of elasticity. The film strips are formed by a controlled tearing of a continuous film while the film is biaxially stretched and bonded to the fabric facings. The fabric facings have gathers formed therein that allow the elastic laminate to stretch at least to the extent that the gathers can be pulled flat.
