Abstract
Abstract An improved semi-automatic bookbinder which permits binding books with full covers using a hot-melt adhesive is shown. Two glue drums are provided, one for applying glue and the other adjustable for removing excess glue when binding without a cover or for adding additional glue when binding with a cover. Also shown is an improved drive system for moving the pages over the applicator, an improved clamp for holding the pages and an electrical system which add flexibility and prevents operation when the glue is not at the proper temperature.
