BINDING ELEMENT STACKING STRUCTURE

摘要

For binding a stack of perforated sheets, an elongated binding element (20) having separable stacking pins (30) disposed on the binding elements (20) to separate and fix the positions of the binding elements (20). The stacking pins (30) are preferably in the form of nesting pins disposed at opposite ends of an elongated spine (22) of the binding element (20) to maintain the binding elements (20) in a stable position relative to surrounding binding elements (20). Nested or stacked binding elements may be so utilized in automatic binding processes such that the stacking pins (30) may be severed from the binding element (20) either before, during, or after the binding process itself.
