Abstract: A method for the manufacture of a slide chart, utilizing high speed, straight line gluing and folding machinery, from a unitary blank having a flat sheet separated into three segments, a first and second segment being provided with openings and forming the faces of the manufactured slide chart, and a third segment having scored lines longitudinally extending therethrough to form a railed slide located between the faces of the manufactured slide chart. The method comprises applying glue to the longitudinal edges of the second or third segment, folding the second and third segment onto each other, applying glue to the longitudinal edges of the first or third segment, folding the first and third segment onto each other, and trimming the transverse edges of the resulting slide chart assembly, thereby freeing the slide to move between a pair of rails and the faces of the slide chart to provide a finished slide chart of substantial precision.
