Loose-leaf Binding
In loose-leaf binding, after being collated, pages are trimmed on all edges and the separate pages are then bound. Individual pages in loose-leaf publications are more prone to wear and tear along the binding than leaves in fully bound publications. The types of bindings described and illustrated on following page:
Plastic Grip Spine: A plastic extrusion is slid over a square-backed or single fold cover, gripping the contents by means of the tension in the plastic material.
Spiral (wire or plastic) binding is the most automated method of loose-leaf binding but does not allow for replacement of single pages to be made. However, spiral bound books lie perfectly flat when open, which is a significant advantage when used for reference material.
Comb (plastic) binding is very similar to spiral binding except that a clip-in device resembling a comb is used. Its advantages and disadvantages are the same as those of the spiral method.
Ring binding, commonly used for price lists, student notes, catalogues and any publication requiring amendment. The rings can be readily snapped open to allow new or amended pages to be added. Ring-bound publications lie flat when open.
Post binding allows the removal and replacement of leaves, but books bound in this way do not lie flat when open.
