A cigarette making line comprising a pneumatic transfer line for transferring rod-shaped elements, the pneumatic transfer line being configured to move a sequence of rod-shaped elements along a path ("P") in a travel direction ("A"), the pneumatic transfer line comprising: a plurality of pneumatic ducts located in succession along the path ("P"), wherein each pneumatic duct extends between a respective receiving station and a respective arrival station and defines within it a working stretch ("O") of the path ("P") along which the rod-shaped elements are fed pneumatically by effect of the expansion of a compressed fluid injected into the pneumatic duct itself, wherein two consecutive working stretches ("O") are alternated with a transfer stretch ("T") of the path ("P") extending between the arrival station of one pneumatic duct and the receiving station of the pneumatic duct located immediately downstream in the travel direction ("A") of the rod-shaped elements, the transfer stretch ("T") being in communication with an environment outside the pneumatic ducts, the cigarette making line being characterized in that: working stretches ("O"), which are independent of each other and in which the rod-shaped elements are fed pneumatically by effect of the expansion of the compressed fluid, and transfer stretches ("T"), in which the rod-shaped elements are mechanically guided and transferred from one working stretch to the one immediately following it, are alternated along the path ("P") whereby the total length of the line is subdivided into independent stretches, the pneumatic transfer line further comprising receiving and relaying means located at each receiving station and configured to receive the rod-shaped elements in sequence, wherein the receiving and relaying means comprise at least one injector configured to inject a compressed fluid into the respective pneumatic duct, at the respective receiving station; the pneumatic transfer line further comprising transfer means located along the transfer stretch ("T") and configured at least to mechanically guide the rod-shaped elements; said transfer means defining a through cavity interposed between, and aligned with, two consecutive pneumatic ducts, wherein the through cavity defines the transfer stretch ("T") and is in communication with the environment outside the pneumatic ducts and wherein the transfer means comprise at least one transfer duct defined by two shells which are movable relative to each other between a closed configuration in which they form at least a portion of the through cavity and an open configuration. working stretches ("O"), which are independent of each other and in which the rod-shaped elements are fed pneumatically by effect of the expansion of the compressed fluid, and transfer stretches ("T"), in which the rod-shaped elements are mechanically guided and transferred from one working stretch to the one immediately following it, are alternated along the path ("P") whereby the total length of the line is subdivided into independent stretches, the pneumatic transfer line further comprising receiving and relaying means located at each receiving station and configured to receive the rod-shaped elements in sequence, wherein the receiving and relaying means comprise at least one injector configured to inject a compressed fluid into the respective pneumatic duct, at the respective receiving station; the pneumatic transfer line further comprising transfer means located along the transfer stretch ("T") and configured at least to mechanically guide the rod-shaped elements; said transfer means defining a through cavity interposed between, and aligned with, two consecutive pneumatic ducts, wherein the through cavity defines the transfer stretch ("T") and is in communication with the environment outside the pneumatic ducts and wherein the transfer means comprise at least one transfer duct defined by two shells which are movable relative to each other between a closed configuration in which they form at least a portion of the through cavity and an open configuration.
