Abstract
A machine for removing book bindings from books so that the paper comprising the pages of the book can be recycled is provided. The machine includes a front and a rear deck, a pusher, a machine frame which extends above the decks and the pusher and a knife assembly (which includes a knife blade) swingably attached to the machine frame and having an up and a down position. The pusher slides back and forth between in and out positions. A book is placed on the front deck and the pusher slides to its in position, positioning the book under the knife assembly. When the book is properly positioned, the knife assembly swings from the up to the down position, cutting off the binding of the book. In some embodiments the invention includes a table frame upon which the front and rear decks are slidably mounted on railings supported by the table frame and have respective in and out positions. Also, the table frame may support a divider bar which is contacted by the knife blade when the knife assembly is in the down position and which is abutted on its sides by said decks when the decks are in their in positions. Thus, when the decks move to their out positions, spaces are created between the divider bar and the decks on both sides of the divider bar through which the sliced pages and bindings can fall.
