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 (114) and a single activation member (112) wherein the activation belt and single activation member comprise a plurality of teeth (124) and grooves (126) that complement and engage one another at a depth of engagement in a deformation zone (120). The depth of engagement can be controlled to increase linearly over at least a portion of the deformation zone such that a web (116) interposed between the activation belt and the single activation member in the deformation zone is incrementally stretched at a low rate of strain.
