A series of nips ( 200, 202, 204, 412, 414 ) formed by intermeshing grooves ( 22, 24, 26, 28 ) provides for a higher degree of stretch, particularly for lightweight webs ( 100 ) by stretching in stages in multiple grooved nips. The ability to adjust the degree of stretch at each nip can provide a high degree and variability of stretch with reduced web damage compared to a single step application of the same stretch. Improvements to the manufacture of lightweight components of personal care products such as diaper backing components are obtained.
