The invention claimed is: 1. A cigarette packing machine comprising: a packing conveyor having a number of packing pockets, each of which receives and houses a respective wrapped group of cigarettes and a respective blank, and is movable along a packing path extending through a loading station where the blanks are loaded inside the relative packing pockets; a feed unit for feeding the blanks to the loading station; a transfer device located at the loading station and comprising a pusher movable back and forth along a transfer path to transfer the blanks from the feed unit to the relative packing pockets in a given transfer direction; and at least one hollow folding spindle, which is located at the loading station, between the feed unit and the packing path and along the transfer path, is movable in the transfer direction along the transfer path, and is penetrated by the pusher to fold the blank. 2. The machine as claimed in claim 1, wherein the folding spindle is movable along the transfer path from a rest position, in which the folding spindle is located between the feed unit and the packing path. 3. The machine as claimed in claim 1, wherein the folding spindle is movable, in the transfer direction, to and from a position of substantial tangency with the packing path. 4. The machine as claimed in claim 1, wherein the folding spindle is movable with the pusher, in the transfer direction, to and from a position of substantial tangency with the packing path. 5. The machine as claimed in claim 1, wherein the feed unit feeds the blanks along a feed path extending through the loading station, and comprises a feed conveyor movable along the feed path and having a number of feed pockets, each for receiving and housing a relative blank. 6. The machine as claimed in claim 5, wherein the folding spindle is movable, in the transfer direction, to and from a position of interference with the feed path. 7. The machine as claimed in claim 5, wherein the pusher is movable, along the transfer path and towards the packing path, from a position in which the pusher is located on the opposite side of the feed path with respect to the packing path, into a work position in which the pusher engages a relative packing pocket(19). 8. The machine as claimed in claim 5, wherein the folding spindle is movable towards the pusher and into a position of interference with the feed path to perform a first folding operation on a relative blank located along the feed path; and is movable with the pusher, but at a first speed slower than a second speed of the pusher, to perform a second folding operation on the relative blank along the transfer path. 9. The machine as claimed in claim 5, wherein the feed conveyor comprises two flexible belts supporting the feed pockets on opposite sides. 10. The machine as claimed in claim 5, wherein: the packing conveyor is moved in steps to feed to, and arrest in, the loading station a group of packing pockets; the feed conveyor is moved in steps to feed to, and arrest in, the loading station an equal number of feed pockets, each of which is positioned, at the loading station, facing a respective packing pocket in the group; and each pair of facing packing and feed pockets is associated with a relative pusher and a relative folding spindle. 11. The machine as claimed in claim 10, wherein the packing pockets in each group are aligned, at the loading station, along the packing path and along a plane parallel to the feed path. 12. The machine as claimed in claim 11 wherein the pushers are integral with one another. 13. The machine as claimed in claim 11 wherein the folding spindles are integral with one another. 14. The machine as claimed in claim 1, wherein the folding spindle comprises a frame having a central passage for the pusher and for a central portion of a relative blank, the frame cooperating with the pusher to fold squarely, with respect to the central portion, two lateral wings of the blank, which are located on opposite sides of the central portion, and each comprise two end tabs; and folding members, each of which projects from the frame in the transfer direction and on the opposite side to the packing path, and engages a respective end tab to fold the end tab squarely with respect to the relative lateral wing. 15. The machine as claimed in claim 1, wherein each feed pocket houses a relative blank by supporting the blank solely by lateral wings of the blank, and leaving a central portion of the blank free, and has a through opening located at the central portion of the blank and permitting passage of the central portion and of the pusher. 16. The machine as claimed in claim 1, wherein, at the loading station, at least one feed pocket of the feed conveyor is aligned with a relative packing pocket in the transfer direction.
