Abstract
A device for inserting sheets into envelopes has a fixed insertion station receiving empty envelopes and a fixed sheet inlet station, which stations are spaced apart from each other, together with a carriage for transferring sheets therebetween and driven between a retracted position beneath the sheet inlet station and an engaged position in an envelope present at the insertion station. The sheet insertion device is characterized in that it includes sheet grasping and pushing fingers (35) fixed to the carriage (33) and projecting slightly above the sheet inlet station (32), together with holding-down fingers (37) mounted above the inlet station and actuated to move between a retracted position and a holding-down position in which they hold a sheet down against the inlet station. The invention is applicable to automatically processing mail.
