Abstract

An angular conveyor for fragile cylindrical objects, particularly in cigarette packing machines, comprises a wheel (1) provided preferably with a plurality of peripheral cells (101) to house the cigarettes (G), these cells (101) being open at least at the perimeter of the wheel (1), and devices (12) for the at least partial closing of the open perimetrical ends of the cells (101), these devices consisting in particular of pairs of fingers mounted on finger-carrying elements (10) which can be moved alternately between a position of at least partial closure and one of opening of the said ends in synchronization with the steps of advance of the wheel (1), the oscillation of these elements being caused by annular cams (15) substantially coaxial with the wheel (1), these cams (15) being provided on both sides of the wheel (1) and being independent of the rotary motion of the wheel (1). According to the invention, the cams consist of what are known as three-dimensional cams (15). These are preferably of the positive type and are housed in sealed annular chambers (18).
