Abstract
An apparatus in a book binding machine for binding books by gluing includes a notch cutting tool for producing notches in the back of the book block, wherein the notches extend approximately transversely of the back of the book block. The notch cutting tool is mounted for cutting notches in a portion of the book block which projects from a mounting device. A rotatably mounted abutment has a cylindrical support surface for laterally supporting the projecting portion against the cutting force exerted by the notch cutting tool. A guide plate is mounted rearwardly offset from the cylindrical support surface of the abutment. The guide plate has a groove surrounding the travel path of the notch cutting tool and the cylindrical support surface of the abutment is located opposite the groove in the guide plate.
