ONE-PIECE LASER/INK JET PRINTABLE DIVIDER

A one-piece divider assembly which is folded over along one edge may be fed into a laser printer, ink jet printer, or photocopier. The assembly includes a divider sheet having a binding edge, a reduced-thickness binding edge region extending inwardly from the binding edge, and a main body with an integral, outwardly-extending tab. The divider sheet has a folding line which is inset from and which runs parallel to the binding edge. The binding edge region has a folding portion defined on one side by the binding edge and on the opposite side by the folding line. The binding edge region also has a non-folding portion adjacent to the folding portion. The folding portion includes spaced holes for a binder. A binding edge reinforcement film may be adhered to at least a portion of the binding edge region. The folding portion of the binding edge region may be folded over at the folding line, and the folding portion may be releasably tacked with a single-use adhesive to the non-folding portion of the divider sheet. In an alternative embodiment, the main body may have an upper sheet and a lower sheet that are adhered to one another.
