Abstract

See full text

A bound collection of leaves having a spine and a method of its manufacture are disclosed. Each leaf of a first plurality of leaves of the bound collection includes a first pattern of tabs by which that leaf is bound. The tabs of the first pattern are distributed along a binding axis of that leaf that is parallel to a spine axis of the spine. Each leaf of a second plurality of leaves of the bound collection includes a second pattern of tabs different than the first pattern by which that leaf is bound. The tabs of the second pattern are distributed along a binding axis of that leaf that is parallel to the spine axis. Each tab of the first pattern and second pattern of tabs extends in a direction orthogonal to the binding axis from within an unbound region to a binding-side edge of that leaf.
