Abstract
To remove binding strips of the type shown in U.S. Pat. No. 4,369,013 from the book or document bound thereby, a debinding machine is used. The machine has a platen on which the spine of the book is supported and a perpendicular back plate against which one face of the book is forced, one binding strip fitting into a gap between the lower edge of the back plate and the platen. Pulling a handle causes a knife blade to enter behind the aforesaid book face and the strip, cutting the studs so that the strip is severed from the book. The other studs may then be pulled out of the holes in the sheets of the book by pulling away the remaining strip.
