ABSTRACT:
The feed device includes a platform (9) adapted to receive at least one mail item (4; 4A, 4B) laid flat on it and a plurality of rollers (10) each having a flat (10B). Said rollers are mounted to rotate under the platform to occupy alternately a first position in which they remain below the platform and a second position in which they project above the platform. A weight sensor (30) is mounted under the platform to carry it, said sensor being responsive to vertical displacement of the platform to deliver a signal (C) indicative of the load applied to it when the rollers are all substantially in said first position.
