A binding machine for a spine binder, wherein the machine has a closing tool which receives an open spine binder of the kind having opposed ribs or fingers adapted to enter aligned holes punched in a sheath of sheets and bind the sheath together, and the tool includes winged mechanism for selectively bearing on the spine binder to close it, arranging the spine binder ribs or fingers in the holes. The tool engages the spine binder in a zipper-like fashion movable along a rail upon which the closing tool is slideably mounted. The machine also has an opening tool for re-opening a closed spine binder by use of a tapered end dimensioned to accommodate the diameter of a closed spine binder, thus forcing the ribs or fingers on the spine apart, and thereby freeing the bound papers from the spine. The invention also includes a binding method for closing an open spine binder having ribs or fingers adapted to enter holes in a sheath of sheets for binding the sheets together, and the method includes the steps of placing the sheath of punched sheets on an open spine binder arranged on a rail upon which a closing tool is slidably mounted, and moving the tool against the spine binder in a zipper like fashion to cause the ribs or fingers to close an secure the sheath.
