Abstract
Abstract A disposable, stretchable laminate product having an inner core of foam material and a method of making the same. The laminate has an inner core of cellular plastic material having compressible foam cells and outer layers of nonwoven material. The outer layers of nonwoven material are wrinkled with laterally extending undulations and the inner core of foam fills these undulations. Because of this construction, the laminate is stretchable only in a longitudinal direction. The laminate is made by stretching a cellular foamed plastic material, thereby reducing its width, adhering the nonwoven material to opposite sides of the foam material while it is stretched, wetting the laminate to relax the nonwoven material thereby permitting the cellular plastic core to return longitudinally to its unstretched position and drying the laminate.
