When it comes to buying a letter folding machine, you need to weigh the amount of work you plan to put the machine through, the various types of setups available, the capacity of the machine, and how workplace friendly it is.

Paper Folding Machine Review

All letter folding machines will be described in terms of the number of duty cycles the machine is rated for. This is where you’re going to start comparing when shopping for a top letter folder. First, decide how many documents you’re going to need to fold in a month. Then, you need to add at least 25% to that number. If you don’t, you run the risk of over-working the machine which can lead to failure or the need for costly premature repairs, which may not be covered under warranty or service plan if you exceed the recommended load for the machine. Then, start shopping for a letter folder that is rated for a duty cycle that matches or exceeds the number that you’ve calculated. The number describes the maximum amount of work you can expect from the machine in a month, but as mentioned, you want to stay 25% below the maximum if at all possible. We reviewed a few of the best models to help you get started.

Review of Volume and Types of Paper to be Folded

If you haven’t worked with this type of equipment before, it may not be evident to you that all paper is not created equal. You have several considerations when it comes to paper, including size and weight. Standard 8.5”X11” paper will likely be handled by all folders, as should the larger legal 11” x 14” paper. However, if you need custom sized paper outside these standard dimensions, you may need a specialized machine designed to handle it.

Using paper of different weights can give a much different feel to your finished products. It’s also important to note that a machine will note which paper weights it is rated for, so if you want to use heavier stock paper you need to make sure the machine you’re interested in is rated for it.

Compare Paper Feed Types and Fold Types

Finally, it is important to understand the difference between the two different feed types of letter folding machines. The entry level options are going to use a roller system to guide paper through the machine. These are known as friction feeders, and they are limited somewhat in the types of papers they work with because of constant pressure against the paper. Air feeders are found on higher end units, and use a vacuum system to feed paper through the machine. The lack of contact means a machine with more flexibility in terms of paper type, but the cost will also be higher for this type of unit.
