METHOD FOR LABELING CONTAINERS WITH PRE-GLUE LABELS CUT FROM A LABEL RIBBON

摘要

A carousel labeling machine for pre-glued labels on a ribbon, which comprises a label cutting and transfer drum (8) fed by a roller (10) for unwinding the label ribbon (9) from a reel (11), and rotating in step with the carousel (2), in the sense that the unwinding roller (10) provides the drum (8) with the label intended for the container that rests on a specific receptacle of the carousel (2). A cutter (13, 14, 15, 16) of the drum (8) is actuated so as to cut the label when a photocell (4) sends a clearance signal as a consequence of the presence of the container. According to the invention, if at least one container is missing on the corresponding receptacle, the photocell (4) sends a command to the unwinding roller (10) to feed the label ribbon (9) to the cutting and transfer drum (8) at a speed reduced with respect to the normal speed.
