Abstract
A method and apparatus for binding sheets using a reactivatable printing substance such as toner comprises a printing device for applying printing toner to a binding edge of a sheet. Printing text can be applied simultaneously to the sheet by the printing device. The sheet is transferred through a preheat station to an overlay location where additional sheets having strips of toner adjacent to a binder edge thereof are overlaid, one at a time. As each sheet is overlaid, the toner strip on the preceding sheet is fused to the uppermost sheet or by another from of sealing energy. Such fusing can be accomplished using a heated platen or wheel that bears upon the uppermost sheet. An opposing toner strip can be applied to the lower face of the uppermost sheet so that a pair of opposing toner strips on each of the opposing sheets are fused to each other.
