  • Envelope feeder with adjustable constant overlap
    Patent number: 5149076
    Abstract: An envelope feeder which can be used on virtually all existing printing machines without the need to synchronize the latter comprises a low-pressure chamber (3), a perforated conveyor belt (4) and an adjustable barrier (6). An overlap with a very small overlap length (5) is thereby achieved. The envelope feeder can therefore be used not only for small envelopes (1), but also for those with very narrow flaps (2).
