A labelling machine for labels printed on pre-pasted continuous film, comprising a rotating carousel (1) provided with means (2) for supporting the individual containers (3) to be labelled, adapted to turn such containers (3) about their own axis, and alignment means (6) and tension adjustment means (7) for the film (5) that unwinds from a reel (4) and a cutting and transfer drum (8) adapted to receive and retain, so that it clings to its own surface, the film that exits from a feeder in order to cut the labels and bring the individual labels, separated after cutting, into contact with corresponding containers (3) supported by the carousel; the cutting and transfer drum (8) comprises a structure for supporting actuation means (10, 11, 12, 13, 14, 15, 16 and 17) for individual blades (10a, 11a, 12a, 13a, 14a, 15a, 16a and 17a) designed to cut the labels, which are mutually spaced circumferentially and are adapted to be each provided with the corresponding blade according to distinct groupings, such that each one causes the presence of a set number of circumferentially equidistant blades, the supporting structure (10, 11, 12, 13, 14, 15, 16 and 17) being adapted to support, so that they are removably locked, for each one of the groupings, an adapted number of circumferential portions of peripheral shells (18, 19, 20, 22, 23, 24, 25, 26, 27, 28, 29, 30 and 31) provided with film retention means and adapted to be inserted in the gaps formed by the blades (10a, 11a, 12a, 13a, 14a, 15a, 16a and 17a) that are present in each one of the groupings, so as to form a continuous cylindrical surface for supporting the film (5). |
