Linerless labels are dispensed from a roll (11) and detached along perforation lines using a set of low speed rolls (18, 19), a set of high speed rolls (20, 21), and a breaker blade (25) between the sets of rolls. The label engaging tip (26) of the breaker blade, and at least one roll of each set of rolls, has a surface that will not stick to the adhesive associated with the linerless labels. One or more conveyor belts (30), also with non-stick surfaces, may transport the linerless labels from the low speed rolls to the high speed rolls, and transport linerless labels away from the high speed rolls. A sensor (28) downstream of the high speed rolls (20, 21) senses the presence of a detached label (42), and then shuts down both sets of rolls.

Des étiquettes sans doublure sont distribuées par un rouleau (11) et détachées sur des lignes de perforation au moyen d'un ensemble de rouleaux basse vitesse (18, 19) et d'un ensemble de rouleaux haute vitesse (20, 21), entre lesquels est prévue une lame de rupture (25). La pointe (26) de la lame de rupture venant en contact avec l'étiquette, et au moins un rouleau de chaque ensemble de rouleaux présentent une surface ne collant pas à l'adhésif associé aux étiquettes sans doublure. Une ou plusieurs bandes transporteuses (30) présentant également des surfaces non collantes peuvent transporter les étiquettes sans doublure depuis les rouleaux grande vitesse. Un capteur (28) situé en aval des rouleaux grande vitesse (20, 21) capte la présence d'une étiquette détachée (42) et arrête les deux ensembles de rouleaux.
