Claim One:
1. An apparatus for activating a stretchable material in multiple directions simultaneously, the apparatus comprising: a. a first roll that is rotatable in a first direction and second roll that is rotatable in a second direction, the first and second rolls each comprising: i. a first region comprising at least one three-dimensional surface feature, wherein the three-dimensional surface feature(s) of the first region of the first roll and the three-dimensional surface feature(s) of the first region of the second roll are complementary and are positioned relative to one another such that when the first roll is rotated in the first direction and the second roll is rotated in the second direction the three-dimensional surface features of the first regions of the first and second rolls intermesh, the intermeshing surface features of the first regions of the first and second rolls being operatively configured to activate the stretchable material in a first direction, ii. a second region comprising at least one three-dimensional surface feature, wherein the three-dimensional surface feature(s) of the second region of the first roll and the three-dimensional surface feature(s) of the second region of the second roll are complementary and are positioned relative to one another such that when the first roll is rotated in the first direction and the second roll is rotated in the second direction the three-dimensional surface features of the second regions of the first and second rolls intermesh, the intermeshing surface features of the second regions of the first and second rolls being operatively configured to activate the stretchable material in a single second direction which is different from the first direction, iii. a buffer region disposed between the portions of the first and second regions that include three-dimensional surface features; and b. a nip between the first and second rolls, the nip being formed by the intermeshing surface features of the first and second rolls, the nip being configured to receive the stretchable material to be activated.
