A hanging file folder assembly, comprising:
- a folder body having a front leaf and a rear leaf, said front leaf and said rear leaf joined along a lower fold line;
- a pair of flaps folded downwardly from an upper edge of said front leaf and said rear leaf along an upper fold line, said flaps defining a pair of open channels extending the length of said front leaf and said rear leaf below said upper fold line;
- and
- at least one hook member integrally formed at an upper edge of each said leaf and including at least two plies of each said leaf folded upon itself.
A method of manufacturing a hanging file folder, said method comprising the steps of:
- providing a generally rectangular sheet of material with a tab protrusion adjacent each corner of said sheet;
- folding said sheet about a lower fold line to define a folder body having a front leaf and a rear leaf joined along said fold line;
- folding an upper portion of each said leaf towards an inside of said folder body along an upper fold line to define a pair of open channels, said channels extending a length of said folder body;
- wherein said step of folding said upper portion of each leaf causes said tab protrusions to be folded in half to create a hook member adjacent upper corners of each said leaf.
A method of assembling a hanging file folder, said method comprising the steps of:
- providing a folder body with a front leaf and a rear leaf, said front leaf and said rear leaf being joined along a lower fold edge;
- securing a reinforcing spine adjacent an upper portion of each said leaf;
- and
- folding an upper portion of each said leaf to enclose said reinforcing spine and to form a plurality of hook members for engaging rails of a hanging file folder cabinet.
