Abstract
The invention relates to an insertion flap for guiding letters during their insertion into the compartments of a rotary drum. It is a question of the axial insertion into the compartment of a drum rotating at an angular velocity .OMEGA. of a letter arriving at speed v. For this purpose, a flap takes up the letter at the interface between the conveying system and the drum and the flap pivots in the rotation direction of the drum at the same angular velocity as the latter and consequently accompanies the latter, whilst increasing the available insertion time before suddenly returning to its initial position for recommencing a new cycle. This makes it possible to compensate rapid speed fluctuations of the drum and bench, whilst a calculation of the departure time for each letter makes it possible to compensate the slow speed fluctuations of the drum and bench.
