How a Folder Inserter works
A folder inserter, also know as a 'envelope stuffer', 'paper folding machine' or 'letter stuffer is an important part of any mailroom. Put simply, their primary purpose is to fold and insert documents into envelopes quickly and efficiently.
Feeders are loaded with stacks of paper documents and carrier envelopes. Sheets and inserts that belong in the same carrier envelope are automatically fed into the system and collected together and arranged one on top of the other. The sheets are then folded using a fold type that's compatible with the carrier envelope.
Meanwhile, an empty carrier envelope is fed in and transported to the inserting area ready for the materials to be inserted. If programmed, the carrier envelope is sealed. Filled carrier tenvelopes then leave the machine by catch try, side exit or stacker.
