Abstract
An automatic spiral binding apparatus for edge binding a book of sheets with a spiral coil includes a book supporting table that is indexable between loading, coil insertion, coil crimping and book discharge stations. The apparatus can accommodate a wide range of book thicknesses, coil diameters and coil pitches. Positioning hooks in the loading station are selected to correspond to the coil diameter and are mounted at an incline to match the coil pitch in a manner which pre-orients the book edge to both the proper curvature and proper pitch to facilitate subsequent threading of the spiral coil into the holes in the edge of the book at the following insertion station.
