Abstract
A drum for cutting linerless labels from a continuous strip and transferring the labels to a container movable with a given trajectory and speed on a machine, the drum including a side surface suitable for guiding the strip by contacting a non-adhesive surface of the labels, the side surface defining a vertical slit, a coaxial and concentric sleeve for centering the drum on a corresponding support spindle, a cutting blade parallel to a vertical direction of the drum, the cutting blade being displaceable in a radial direction from a position retracted inside the drum to a position at least partially extended through the vertical slit outside the side surface of the drum, a fixed cam relative to which the drum rotates and that is configured to press against the cutting blade so as to cause the cutting blade to extend out in a predefined angular position, and a seat that extends in the vertical direction (Z-Z) and is connected to the cam and which is suitable for engagement with a corresponding fixed reference pin in order to determine a predefined angular position of the cam, wherein the drum is configured to retain the strip against the side surface of the drum.
