Labelling machine for labels printed on pre-pasted continuous film

A labelling machine for labels printed on pre-pasted continuous film, comprising a rotating carousel provided with means for supporting individual containers to be labelled, adapted to turn said containers about their own axis, and further comprising alignment means and tension adjustment means for the film that unwinds from a reel and a cutting and transfer drum 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 supported by the carousel, wherein the cutting and transfer drum comprises a structure for supporting actuation means for individual blades 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 predetermined number of circumferentially equidistant blades, said supporting structure being adapted to support, so that they are removably locked, for each one of said groupings, an adapted number of circumferential portions of peripheral shells provided with film retention means and adapted to be inserted in the gaps formed by the blades that are present in each one of said groupings, so as to define a continuous cylindrical surface for supporting the films.
