Binding Machines: A Buying Guide
A binding machine punches a row of holes along the edge of a document and holds the pages together with a plastic comb, a double-loop wire or a spiral coil. Perfect binders glue a cover around the spine instead, like a paperback.
The quick rule: pick the binding style first (comb, wire or coil), then match the punch capacity to how many sheets you can punch at once and the binding capacity to your thickest document.
What to look for
- Binding style. Plastic comb can be reopened to add pages. Double-loop wire looks sharper and lies flat. Spiral coil turns 360 degrees and survives rough handling. Some machines take interchangeable dies for all three.
- Punch capacity. Sheets of 20 lb paper per punch stroke; thicker stock and covers reduce it. Makers sometimes give a thickness instead.
- Binding capacity. The thickest document the comb, wire or coil (and the machine) can bind, in sheets or diameter.
- Manual or electric. Electric punches use a button or foot pedal and suit daily runs; manual levers suit occasional jobs.
- Punch length. Most machines punch letter-size edges; open-ended throats let you punch longer documents in two strokes.
- Modules. Some systems split the punch from the binder, closer, coil inserter or crimper, so one punch can feed several binding stations.
