<p>The invention concerns an apparatus (1) comprising a station (6) for picking pieces (2) from a stack (3) of pieces and a station (7) for depositing each of said pieces (2) on at least one receiving element (4, 5) and, between the two stations (6, 7) a transfer element (8) which, provided with at least a grip device (9), is mounted rotatable about an axis (8A) and driven in rotation, in particular in a predetermined direction (S8), said grip device (9) comprising: a so-called transfer surface (10), with substantially identical shape and dimension as those of a piece (2), and in which surface emerges at least a passage (11) selectively linked to an air suction device (13), by a dispensing device, controlled by vacuum control to pick up each piece (2) and transfer it at least partly towards the depositing station (7), at least a positioning stop element (15), oriented to co-operate with a piece (2) arranged against the transfer surface (10) and to constitute an obstacle to the displacement of said piece (2) in a direction opposite to the direction (S8) imparted to it by the rotation of the transfer element (8).</p> |
