What Features Should I Look for in a Comb Binding Machine?

If you are in the market for a plastic comb binding machine, you might be wondering which one will best fit your needs. There are a handful of features that can make a comb binder stand out amongst the rest. To help you out, here are our favorite details to look out for.

• Integrated Comb Spreader
  
  

  It might go without saying, but to insert a spine into your document, you need a way to open and close your combs. Many machines have a comb spreader built in for ease of use. You should look out for their binding capacity. If you want maximum versatility or need the ability to bind extra-large documents, up to 425 pages, you will want a spreader that can handle the full range of 3/16” to 2” plastic combs.

  Additionally, you might want to consider adding a separate comb opener to your workflow. That way, you can maximize efficiency by having one person punch while another person binds your documents.



• Punching Length & Open Throat
  
  

  You should have no problem finding a machine that can accommodate letter-sized paper (8.5” x 11”), but if you want to bind anything larger, you will want to look for two specific features.

  1. Punch Length - If you frequently have oversized projects, your best bet is to simply find a binder that has a maximum punching length of at least your largest document size.
  2. Open Throat - However, if you are okay with a slightly longer binding process, a comb punch with an open throat should also be able to get the job done.

     When you see this feature listed, it means that the punching slot is open on one side. This allows excess paper to extend past the machine, accommodating a wider range of paper sizes. You can punch any size document that doesn’t exceed double the original punching length.

     Simply punch the first half, flip your page around, line it up, and punch the second half. The process will take a bit longer, but it allows you to accomplish way more without having to invest in a larger machine.



• Disengageable Dies
  
  

  It is ideal to have a binding machine with disengageable dies, especially if you are punching anything other than letter-size paper. Punches with disengageable dies allow you to customize your hole pattern. This prevents accidentally punching a partial hole that clips through the edge of your paper.



• Margin Control
  
  

  Controlling the depth of your punch is an essential feature to look for. It allows you to control the distance between the edge of your document and where the holes are punched. Adjusting this distance helps you create books that are easier to read, ensuring the pages turn freely, and helps prevent holes from getting torn with regular use. You should always set your margin according to the number of pages you have so they fit properly on your comb, especially with oval combs.



• Durable Construction
  
  

  Since you’re spending good money on a comb binding machine, it’s important to choose one that is durably constructed. The most durable machines contain metal parts and can withstand years of use. Whatever machine you choose, it should at least have a metal comb opener as it will be used very frequently, and any other material will be prone to breaking.



• Electric v. Manual
  
  

  If you plan on binding in large batches, you might want to consider the extra investment of an electric comb binder over a manual option. Manual punches are great, but if you need to punch 10+ documents in one session, they can get tiring. Electric punches take strain off the user with button or foot pedal operation, preventing fatigue and allowing for a faster punch.



• Punching Capacity
  
  

  You should choose a machine that can punch a reasonable number of sheets per pass. What is “reasonable” for you depends on the average thickness of your documents. If you are binding a 10-page document with a 5-sheet punch, you could finish punching in 2 batches. Binding a 50-page report with that same machine would take 10 lifts before you could bind your document. You might be better off using a machine with a 25-sheet capacity.



• Design
  
  

  The design of a comb-binding machine is important to take into consideration. Not so much the look, but the special additions that make it easier to use. For example, it’s helpful to choose a manual punch with a D-shaped handle so both left and right-handed people can use it, and it can be used with both hands, reducing strain. Some machines also have directions printed on them or size references for combs and margins. This makes operation a breeze.



• Special Features
  
  

  There are a number of special features that may interest you.

  1. Rotary edge guides can help you punch the holes more easily and produce stronger documents.
  2. A vertical punching mechanism can help you align your paper properly.
  3. Self-sharpening dies help your punch last longer.
  4. Finally, a comb storage tray gives you extra space for your supplies.


• A Good Warranty
  
  

  The comb binding machine you select should have a good warranty. Nothing is better than a company that has faith in their machine and makes a commitment to keeping yours working at its best. Comb binding machine warranties can last anywhere from 90 days to a year or two. Be sure to find out if the warranty is for a replacement or a return-and-repair service. Replacement warranties are extra convenient.
