    Abstract: A method and apparatus is provided which uses activation members for incrementally stretching a web at a low strain rate. The activation members include an activation belt and a single activation member wherein the activation belt and single activation member comprise a plurality of teeth and grooves that complement and engage one another at a depth of engagement in a deformation zone. The depth of engagement can be controlled to increase linearly over at least a portion of the deformation zone such that a web interposed between the activation belt and the single activation member in the deformation zone is incrementally stretched at a low rate of strain.

    Abstract: Apparatuses for forming discrete deformations in web materials are disclosed. The apparatus may be in the form of nested or other arrangements of multiple rolls, in which the web is maintained in substantial contact with at least one of the rolls throughout the process, and at least two of the rolls define two or more nips thereon with other rolls. In some embodiments, rolls can be used to expose a different side of the web for a subsequent deformation step. In these or other embodiments, the rolls can be used to transfer the web between rolls in such a manner that it may offset the rolls and/or web so that subsequent deformations are formed at a different cross-machine direction location than prior deformations.
