Abstract: A labeling machine, particularly of the reel-fed type, includes a framework (2) which supports an application element (10) provided with at least one rotating member (11) adapted to transfer the individual labels on corresponding containers moved by a conveyance element (50); the application assembly is fed by a driving element (20) which unwinds the ribbon of the labels from a reel which is supported by a rotatable support (31) mounted on at least one reel supporting assembly (30). The labeling machine includes an articulation element (100) in order to move reversibly the reel supporting assembly from a working position, in which the rotation axis (3000) of the rotatable support is substantially parallel to the rotation axis (1000) of the rotating member, to a loading position, in which the rotation axis of the rotatable support is transverse to the rotation axis of the rotating member.
