The stack of envelopes is controlled by a microswitch which keeps the stack a constant height at all times. As the press picks up the envelopes the microswitch puts more envelopes under the bottom of the stack. The feeder motor only runs when the press needs more envelopes. No timing device is needed. The T-100 can feed in excess of 10,000 envelopes per hour and the speed of printing is controlled by the printer.
Adjustment is fast and easy.
Up to 500 envelopes can be loaded at a time and more can be added at any time with the press running. There is no need to stop the press until the job is finished. Big savings can also be made on short runs of hard to feed envelopes or other hard to feed materials. The feeder is shipped with the side covers, front and rear stock guides removed. It can be fully assembled with only a Phillips head screwdriver.
