This device comprises a gripper (9) constituted by at least one pair of rollers (40) have parallel axes, which are located side by side near each other and are rotationally driven in opposite directions, the gripper (9) furthermore comprising at least one tube (16) which can move vertically and is associated with each pair of rollers (40), each tube (16) being capable, in the lowest position, to come into contact with a pliant product (3) and to seize it by means of a suction which is exerted within this tube, and then, while it moves to its high position, being capable of raising the said product (3) in such a way as to bring it between the rollers (40) so that, by virtue of their rotational motion in opposite directions, it is engaged and held between them by jamming. <IMAGE>
