Abstract
A textile web from which elastically stretchable diaper closures can be stamped is made by first passing a pair of nonwoven textile webs longitudinally through a first laminating station at a predetermined first speed and inserting a plurality of longitudinally extending and transversely spaced strips of an elastic polymer between the webs at the first laminating station. This laminates the webs and strips together into an intermediate laminate having longitudinally extending zones where the webs are directly laminated to each other alternating with longitudinally extending stretch zones where the elastic strips are laminated between the webs. This intermediate laminate then passes through a second lamination station downstream of the first lamination station at a predetermined second speed smaller than the first predetermined speed. In the second lamination station respective inelastic strips are adhered to opposite faces of the intermediate laminate in the zones between the stretch zones.
