An apparatus for simultaneously activating two or more portions of a web in different directions. The apparatus includes a pair of intermeshing activation rolls with three-dimensional surface features disposed thereon. The three dimensional surface features are arranged in discrete regions on the rolls such that at least two of the regions provide different directions of activation. The rolls include one or more buffer regions positioned between the discrete regions on the roll that provide different directions of activation.
