Abstract

Selon l'invention, une bande d'étiquettes (2t) acheminée à partir d'une toile originale de bande d'étiquettes (2r) est découpée au moyen d'une coupeuse (211) pour former une étiquette (2) de longueur déterminée. L'étiquette (2) découpée est acheminée vers un tambour de transfert d'étiquettes rotatif (22) à partir de la coupeuse (211), selon un intervalle déterminé, et elle est déplacée du tambour (22) à une face périphérique d'un support rotatif (10). Ce dernier (10) est conçu pour soutenir l'étiquette (2) selon l'intervalle déterminé. La coupeuse (211) est maintenue coulissante par un bâti (212) oscillant, l'axe de rotation du tambour de transfert (22) servant de centre. Les fluctuations de force de traction de la bande d'étiquettes (2t) entre la toile originale (2r) et la coupeuse (211) sont supprimées par un mécanisme danseur (250) et un mécanisme de liaison réglant la longueur de trajet (260). Pour acheminer vers le support rotatif l'étiquette obtenue par découpe de la bande d'étiquettes au moyen de la coupeuse et fabriquer une feuille de sac d'extraction, les fluctuations de la force de traction de la bande d'étiquettes (2t) avec une transmission intermittente de l'étiquette à la coupeuse sont réduites et la vitesse d'acheminement d'étiquettes vers le support rotatif est accrue.
