Abstract
This invention relates to a device for moistening envelope flaps, comprising a reservoir of liquid, means for pumping this liquid and, disposed transversely with respect to a direction of advance of the envelopes and inclined with respect to a horizontal plane for supporting these envelopes, means for spraying on the envelope flaps a part of the liquid pumped from the reservoir of liquid. This inclination of the spray means corresponds to the angle of inclination of the flaps of envelopes with folded down flaps.
Claims8
Device for moistening envelope flaps, comprising;
- a reservoir of liquid;
- a pump for pumping this liquid;
- a separator for respectively separating the envelope flaps from bodies of the envelopes;
- a bar perforated by orifices from which droplets of liquid pumped from the reservoir are sprayed onto the envelope flap, said bar extending from said separator transversely with respect to a direction of advance of the envelopes and inclined with respect to a horizontal plane supporting the envelopes;
- and
- a seal provided at a junction between said separator and said perforated bar,
- wherein said inclination of the perforated bar corresponds to an angle of inclination of the flaps of envelopes with folded down flaps, and
- wherein said reservoir of liquid comprises an opening for collecting the liquid sprayed in excess through the orifices of the bar and channelled by a recovery gutter.
