HOT MELT STICK FOR BOOK BINDING Proposed Classification ~ U.S. Cl. 281/21R William Perun Int, Cl. B42d 1/00

The existing art of hot melt binding of books requires the adhesive to be pre~ melted and applied in a liquid state to the bound edge of a stack of paper. This requires not only extensive mechanisms to heat the material to the melting point and apply it, but also requires that some kind of spine preparation be performed on the stack prior to glueing.

By mixing the binding adhesive with a usoapu carrier, the adhesive can be formed into a cold solid approximating a crayon. The adhesive can be applied by rubbing the crayon adhesive along the bind edge of each sheet to apply a thin layer thereon. When several sheets have been gathered, heat can be applied to the stack and an adhesive bond will be formed. The soap acts as a carrier and enables the flow of hot melt material.

In addition to soap, bipolar materials could be added to the suspension to enable microwave heating of the stack, Also a ferromagnetic material could be added, such as tiny metal filings, to allow for induction heating.
