Letter folding machines for folding brochures, direct mail, letters, promotional mail.
One of the jobs that you might want to automate when it comes to posting a lot of mail is letter folding. If you are in the business of sending out a lot of promotional mail or newsletters, you might have hundreds of thousands of letters and brochures to send. Letter folding can be automated with the help of letter folding machines.
Just like any other mailing equipment, letter folding machines also come in various sizes and capabilities. Low-end letter folding machines can process a few hundred letters per hour whereas high-end equipment is capable of operating at speeds from 1500 to 1800 sheets per. Another variation in the folding machine comes in the capability of doing different kinds of folds. Standard kind of folds are c-fold (standard letter), Z-fold, accordion fold, double fold , rightangle fold and brochures fold.
Most commonly the sheets are stacked and fed in to the letter folding machine through either a friction feeder or a vacuum feeder. Friction feeder uses rollers and the rubber wheels to pull the letters in just like a common printer does. Vacuum feeders on the other hand use air suction to pull a letter. The advantage of friction feeders is that it is relatively cheaper than a vacuum feeder folding machine. However, the rubber wheels and the rollers have a tendency to wear out with frequent use. Also, these machines can sometimes smudge the paper specially when it’s freshly printed. For handling glossy and coated paper, vacuum feeders are the best. The disadvantage of vacuum feeders is that this is mostly available on high-volume letter folding machines which tend to be expensive.
You may also want to buy a letter folding machine that has a batch counter or a totals counter. Not only will this help you keep count of how many letters and brochures you have folded but it also keeps the machine from folding too many sheets together.
Some machines come with a built in memory where you can store a certain permutation. The memory setting allows you to set the instructions for processing a particular job once and then call up the job and we need to apply the same permutation.
As is the case with the, printers, paper jams are a common problem with letter folding machines. Well-designed letter folding machines can give you manual access to the rollers easily to clear the jam, letting you resolve the problem yourself quickly and easily.
You may even want to consider a letter folding machine that also has a feature of inserting your documents into the envelopes.
