Abstract:

A method of producing a laminate material by joining an incrementally stretched first flexible sheet material to a second flexible sheet material. A series of nips formed by intermeshing grooves provides the first flexible sheet material with a high degree of stretch and provides the resulting laminate has a high degree of extensibility. The width of the first flexible sheet material is maintained through the incremental stretching to result in high efficiency of utilization of the first flexible sheet material in production of the laminate.
