<p>A device for centring a plurality of cylinders (6) of single-use syringes in automatic filling and packaging machines, which cylinders are seated in through holes (70) provided in a support (7), comprises: a plurality of foils (1) having their edges provided with recesses (16) and positioned with the longitudinal axes parallel and lying on at least one plane, which foils are hinged at one end in such a way as to be able to effect rotations around their own longitudinal axes, a plurality of non shaped rods (2), positioned parallel and alternated to the foils (1) on the same plane or on the same planes, which rods co-operate with the recesses provided in the edges of the foils to form seats for locking the cylinders in place; a mechanical actuator (3), acting on the ends of the foils with a system of levers and/or gears, which actuator can assume two positions, in correspondence with which the foils are oriented with the surfaces lying in the plane or in the planes containing the longitudinal axes and respectively with the surfaces orthogonal to said plane(s). <IMAGE></p> |
