Abstract
A mechanical activation system has a first activation member, a second activation member, an activation zone, and a non-slip zone. The first activation member has a first plurality of teeth, and the second activation member has a second plurality of teeth. The first plurality of teeth is capable of intermeshing with the second plurality of teeth. The activation zone includes a first portion of the first plurality of teeth and a first portion of the second plurality of teeth. The first portion of the first plurality of teeth and the first portion of the second plurality of teeth include teeth having continuous tips. The first non-slip zone includes a second portion of the first plurality of teeth or a second portion of the second plurality of teeth. The second portion includes a tooth having a discontinuous tip.
Claims1
A method of mechanically activating a substrate comprising the steps of:
- obtaining a substrate;
- providing the substrate to a mechanical activation system;
- winding the substrate over the surface of a central disk, such that at least a portion of the substrate folds about a side of the central disk;
- intermeshing the substrate between a first plurality of engagement elements disposed on the side of the central disk and a second plurality of engagement elements disposed on the side of an outer disk;
- and
- reducing slippage of the substrate with respect to the central disk and the outer disk in the cross-direction by providing a portion of the first plurality of engagement elements or a portion of the second plurality of engagement elements with discontinuous tips,
- wherein the discontinuous tips comprise discontinuities having a depth between 0.2 mm and 5 mm,
- wherein the discontinuous tips have a coefficient of friction between 0.8 and 1.0.
