Types of Letter Folding Machines

Folding machines come in three different types based on the way the paper feeds into the machine. The first type is a manual feeder that requires you to load one to five sheets at a time.

The other two types are automatic, allowing you to load a large amount of paper at a time. Friction feed machines will use a silicone or rubber wheel to pull the paper, while air feed uses suction to pull the paper.

What to Look for When Evaluating Paper Folding Machines

There are six basic questions you should ask when shopping for a paper folding machine. This will help you narrow down your options to find the right folding machine for your needs.

  1. What type of paper will you use? 

commercial letter folding machine ReviewIf you plan to use cardstock or standard paper then you can look at machines that use a friction feeder. However, if you plan to use slick or glossy paper then you'll need to look at an air feeder. Using a friction feeder on glossy paper will result in a lot of paper jams.

  1. How thick is your paper? 

Look at the machine's minimum and max paper thickness capabilities. If you are using a standard 20# copy paper you should be fine with any machine. When your paper gets thinner than 12# or thick card stock then you need to keep an eye on your machine.

  1. What fold do you need?

You're buying a folding machine, so you should check to make sure the machine does the fold you need. Most machines will list the different folds that it is capable of.

  1. What folding volume do you have?

Machines can vary in volume from a few dozen folded sheets to a few thousand a day. Don't confuse the motor speed with the daily duty cycle. These numbers do not always correlate.

  1. Do you need your folded paper kept in order?

If you are folding specific documents like bills, invoices, or customer statements, you'll need the paper to stay in a particular order. Look for a machine that has a powered exit conveyor.

The conveyor slows down the speed of the paper. You may want to consider a conveyor even if you don't need the paper in a particular order as it will keep things neat and tidy.

  1. Where do you plan to fold your paper?

Folding machines vary greatly when it comes to size. If you plan to keep it on your desk, you'll need to keep this in mind. You also need to think about the weight of the machine as larger ones can become quite heavy.

How Does a Letter Folding Machine Work?

The machine is going to start by pulling a sheet of paper into the body of the machine by using either the friction wheels or air suction.

The paper is then moved onto the first folding plate. This is where the first fold happens. It will then get moved around the friction plates based on the type of fold you have programmed the machine to do.

Once the paper has made its way through the required folding plates, it ejects from the machine and into the exit tray.

What Are The Types of Fold Letter Folding Machines Can Do?

There are 11 types of folds that you will see letter machines do. The one you select will depend on what your intended use is for the paper.


This type of fold will also get referred to as a “C” fold. This is the most common type of fold.

Examples of tri-folding are brochures, invitations, or mailers. There are a center panel and two flaps that fold over each other on top of the centerpiece.

Half Fold

A half-fold is what you'd expect from the name; a piece of paper folded in half. Greeting cards are a common example of a half fold.

Z Fold 

The Z fold is like the tri-fold except that instead of the two outside flaps folding over the middle on top of each other, one goes on the front and one goes on the back.

Sometimes this type of fold is referred to as an accordion fold. Most utility bills come folded in this format.

Double Parallel Fold

Customer reports often have a double parallel fold. Typically, a legal sheet of paper arrives folded in half and then folded in half again.

Gate Fold

Magazine covers and books will have a gatefold. This type of fold is like the tri-fold but the outside flaps have their edges meet in the middle instead of overlapping.

Closed Gate Fold 

This is a rare type of fold that you might only see for brochures. It is exactly the same as a gatefold, but the center panel has a fold down the middle.

Cross Fold

Also known as a French fold, greeting cards and wedding invitations are the only things that use this type of fold. It isn't common because it is a more complicated process that requires the machine to run the paper through twice for two separate folds.

First, the paper runs through and gets folded in half. Then it gets folded in half again.

Church Fold 

You might hear this one referred to as a right-angle fold. Start with a tri-fold design, but one flap is smaller in width than the center panel.

Engineering Fold 

This is one of the most obscure folds available. It is a modified Z fold where only half the paper is accordion folded. This works well if you need to organize report or brochure materials.

Baronial Fold 

This is the most complicated type of fold and many folders won't be able to achieve it. This is okay though, as its only real application is for cartography or map folding.

It involves a series of individual folds where the paper gets folded in half and then in thirds.

Cross Letter Fold 

Not quite as complicated as the last fold, this one sees the paper folded in half and then folded into a tri-fold.

How Many Envelopes per Hour Can a Letter Folding Machine Stuff?

Depending on the machine you buy, the number of envelopes you can stuff in an hour will vary. A decent mid-volume model will stuff 2,400 envelopes in an hour. A high volume machine can process upwards of 12,000 in an hour.

How Much Do Automatic Letter Folding Machines Cost?

Paper Folding MachineFor a small manual feed machine, you can expect to pay around $200 to $300. For an automated friction-free machine you can expect to pay anywhere from $800 to $3,000.

Air feeders are going to be a lot more expensive and can run you from $5,000 to $10,000. If you need a high-volume air feeder the price can climb further to $10,000 to $15,000.

If you are planning on mailing your folded paper then you should opt for a folder that also has an envelope inserter. Then it will become a part of your mailing equipment. These dual machines start at around $4,000.

Top Letter Folding Machines Wrap up

When looking at a letter folding machine, think about the type of paper, the type of fold, and the volume you'll need. This will let you narrow down your options to a machine that will meet your needs.

Remember that the more complicated the fold and the higher the volume the more expensive you can expect the machine to be.

For the most automation, look for a machine that will also stuff the folded paper into an envelope. this will reduce your labor costs even more.
