DRUM FOR CUTTING AND TRANSFERRING LINERLESS LABELS FROM A CONTINUOUS STRIP TO A MOVING CONTAINER AND APPARATUS EQUIPPED WITH SAID DRUMS

摘要

Drum (300) for cutting linerless labels (2;102) from a continuous strip (1;101) and transferring the labels to a container (3) movable with a given trajectory and speed on a machine (4), comprising: - a side surface (301) suitable for guiding the strip (1;101) by means of contact with the non- adhesive surface (2a) of the labels (2;102); a coaxial and concentric sleeve (310) for centring the drum on an associated support spindle (311); - at least one cutting blade (330) parallel to the vertical direction (Z-Z), housed inside a corresponding vertical slit (302) in the side surface (301) of the drum and displaceable in a radial direction from a position retracted inside the drum into a position extracted outside the side surface of the drum itself; - a fixed cam (320) relative to which the drum rotates and which presses against said at least one blade (330) so as to cause it to move out in a predefined angular position; a seat (312) which extends in the vertical direction (Z-Z) and is connected to the cam (320) and which is suitable for engagement with a corresponding fixed reference pin (313), situated outside the drum, in order to determine a predefined angular position of said cam (320); - means (334) arranged between the blade (330) and the drum (310) for recalling the blade (330) into its retracted position; - means (301a,350) for retaining the strip (1;101) against the side surface (301) of the drum (310).
