Paper Folding Machines
The fold pattern is the first question, because a machine that does not offer the fold you post is no use however fast it runs. Letter and half folds cover most business mail; accordion and gate folds suit brochures. Sheets per minute matters once a run passes a few hundred. Check the maximum paper weight, since heavier stock jams lighter machines. See envelopes, DL envelopes and printers.
