Abstract
The objects (6) fall into a well (10) where their fall is slowed down by slanted blades (13) covered by a damping layer and situated in front of a counter-wall (14) from which they are separated by a gap (16). The counter-wall (14) is elastic so as to make the objects falling onto it rebound towards the lower blade. An outgoing track of the well (26) having a round shape is covered with a damping layer which absorbs the free fall energy at the outlet of the device. The invention can be applied to the continuous bulk carrying of fragile objects, such as pellets.
