Definitions

  • the invention relates to a device for lifting envelope flaps on feeders of letter closing machines.
  • This device has a scanning device that controls the air flow of a printing device depending on the processing of letters that are already closed or still open.
  • This device requires a hold-down device, the pressing force of which may need to be matched to the letter size and the air flow rate.
  • the invention had for its object to provide a device for lifting envelope flaps, which allows the processing of both open and closed letters, regardless of their strength, without the use of a hold-down device.
  • the feed is assigned a perforated suction plate with a subordinate separating plate, one edge of the suction plate being located below an edge of the separating plate.
  • the envelope 10 runs through the conveyor shaft 21 and the pressure roller 22 via a perforated suction plate 30.
  • a separating plate 40 is arranged downstream of the suction plate 30.
  • the edge of the suction plate 30 facing the separating plate 40 lies below the front edge of the separating plate 40, viewed in the transport direction of an envelope.
  • the surface of the suction plate 30 is convex.
  • scanning devices not shown, e.g. Photoelectric sensors, air sucked out through the perforation.
  • the envelope flap is sucked in by an unsealed letter 10 guided over the suction plate 30 and slides under the separating board 40.
  • the downstream moistening device 50 wets the rubber coating and a pressure device, not shown, closes the letter.
  • the guiding surface for the envelope 10 is provided as a scanning device in front of the conveyor shaft 21 with a recess which does not support the envelope flap with respect to the majority of the envelope 10.
  • the envelope flap is thus exposed to gravity and hangs in the recess, for example interrupting a light beam.
  • Position detectors determine whether the letter is closed and the suction device is controlled accordingly.
  • the above-mentioned device of air flow ejection or a simplified suction device can also be used.
