The hopper, loaded

Separator and buckle gap

The separator, in place

Running, shot in St. Louis
The width most mailing and print work falls inside, on a frame that does not mind a stack with a mind of its own.
The piece meets the separator and buckles instead of getting pinched between two rollers. One leaves the stack, the one under it stays where it is — which is why uneven, glossy and stuffed work runs off the same pile as everything else.
Stuffed envelopes are uneven by definition — thicker at one end, sometimes at the corner. Buckle separation works off the leading edge, so the lump behind it stops mattering.
Four options, all of them available on the R-14. Leave off the ones the job does not need.
Sets the gap into your line and holds it as the run heats up.
Counts what actually fed, so the number on the screen is the number in the box.
Stop on a count, or feed one piece each time the machine downstream asks.
Height-matched to the equipment it feeds.
Against the other two, by the width of the piece you are feeding.
Box it up and mail it to St. Louis. We will run it on the R-14, film it, and tell you straight whether this is the machine for it.
