ABSTRACT:
An apparatus for opening a book having a plurality of pages held in assembled relation with adjacent foredges substantially in contact with one another. The apparatus includes a rotatable pin for initiating separation of pages of the book by contacting and entering the book at one end of the adjacent foredges to thereby cause one of the pages to be separated from a next adjacent of the pages at a selected location in the book. Additionally, at a ribbon inserting station, a ribbon inserter can be provided to insert a ribbon into the selected location in the book between the one of the pages and the next adjacent of the pages. The apparatus may also include a knife assembly downstream of the rotatable pin which is adapted to maintain separation of the pages upon entering the book at the selected location for any purpose such as accommodating insertion of a ribbon by the ribbon inserter. With this arrangement, the book opening apparatus is well suited for opening a book without damage to the pages thereof.
