A helical coil is inserted into holes at an edge of a book by a machine which is adjustable for different diameters of coil. The face of the book sits on a platen and the coil is driven by a roller while the edge of the book is supported on a plurality of spine formers having an arced surface for shaping the edge of the book and an end of the book is engaged by a side lay member at an angle to incline the holes at the angle to receive the turns of the coil. The flat spine formers are carried on supports which rotate so as to allow the turns of the coil at the pitch angle to pass the spine formers. For different book thickness and coil diameter, the arced shape of the spine formers, the spine former angle and the lay angle are changed manually.

A machine for cutting and crimping the ends of a helical coil inserted into holes at an edge of a book to hold the coil in place is adjustable to accommodate different diameters of coil. A guide member for centering the axis of the coil in a centering direction is adjustable to accommodate different diameter coils and for adjusting the location of the axis in an adjustment direction at right angles to the centering direction depending upon the diameter of the coil. A cutting device has a blade movable in a slot of an anvil to shear on one side and to bend on the other side to form a crimped end portion. The adjustment of the axis causes the cutting device to cut the end portion longer for larger coils. The cutting device is adjustable to rotate the anvil relative to the axis to accommodate different helix angles.

A helical plastic coil is used for binding a collated book having a stack of pages with aligned holes along one edge of the book where a leading end of the filament is fed into a first hole at a first end of the book and the coil is rotated about its axis such that the leading end is threaded through the holes by entering each of the holes until the coil is threaded through all of the holes. The leading end of the coil is sheared by an anvil and blade so as to define a leading apex and a leading surface inclined rearwardly from the leading apex along the filament and across the filament. The leading apex is arranged such that, as the leading end enters each of the holes in turn, the leading apex is located on the leading end of the filament at a position thereon facing away from the trailing end of the coil and spaced from the end of the hole facing the first end of the book.
