Ensemble de fabrication de flans, en particulier de collets en matériau d'emballage, de préférence pour des emballages de cigarettes, en particulier en vue de l'exécution du procédé selon l'une ou plusieurs des revendications précédentes, et présentant au moins un cylindre de gaufrage (27a) doté d'au moins un segment de gaufrage (32a-32c), par lequel une nappe (25) de matière peut être dotée de gaufrages (20'-20''', 23) pendant une phase partielle de rotation du cylindre de gaufrage (27a), ainsi que d'au moins un segment libre (33a-33c) qui ne forme pas de gaufrages (20'-20''', 23) pendant une autre phase partielle de rotation, et un cylindre (38a) de découpe de séparation disposé en aval du cylindre de gaufrage (27a) et présentant des moyens individuels de séparation (39), en particulier des couteaux de séparation par lesquels la nappe (25) de matière peut être découpée en particulier de manière cadencée en flans individuels (26),
    caractérisé en ce que
    le cylindre de gaufrage (27a) est entraîné par un dispositif d'entraînement (36) et transfère des forces de transport sur la nappe (25) de matière en particulier au cours des phases pendant lesquelles il forme les gaufrages (20'- 20''', 23) dans la nappe (25) de matière et
    en ce que le cylindre (38a) de découpe de séparation présente au moins un segment d'entraînement (41) par lequel des forces de transport peuvent être transférées par le cylindre (38) de découpe de séparation sur la nappe (25) de matière dans une phase de rotation partielle au cours de laquelle le cylindre de gaufrage (27a) ne transfère pas de forces de transport sur la nappe (25) de matière.
  5. Ensemble selon la revendication 4, caractérisé en ce qu'un dispositif (44) de flexion de la nappe (25) de matière le long de son axe longitudinal est disposé entre le cylindre de gaufrage (27a) et le cylindre (38a) de découpe de séparation, en particulier un dispositif (44) présentant plusieurs moyens de guidage (45, 47a, 47b), en particulier des rouleaux de guidage disposés de telle sorte qu'ils définissent une piste incurvée de transport (48) suivant laquelle la nappe (25) de matière est guidée et entre lesquels la nappe (25) de matière peut être transportée.
  6. Ensemble selon la revendication 5, caractérisé en ce que le dispositif (44) d'incurvation de la nappe (25) de matière présente au moins un premier moyen de guidage (45) disposé en particulier au niveau de l'axe longitudinal de la nappe de matière et qui repousse le côté inférieur de la nappe de matière, ainsi que deux moyens de guidage (47a, 47b) disposés au niveau des bords latéraux de la nappe (25) de matière et qui repoussent chacun le côté supérieur de la nappe de matière.
  7. Ensemble selon l'une ou plusieurs des revendications 5 et 6, caractérisé en ce que le cylindre (38a) présente des couteaux de séparation (39) disposés à distance les uns des autres dans la direction périphérique, un segment d'entraînement (41) situé en avant dans la direction de rotation standard du cylindre de découpe de séparation étant associé à chaque couteau de séparation (39) et pouvant transférer les forces de transport sur la nappe (25) de matière.
  8. Ensemble selon l'une ou plusieurs des revendications 5 à 7, caractérisé en ce qu'en aval du cylindre (38a) de découpe de séparation est disposé un cylindre d'accélération (50a) qui permet de sortir de la nappe (25) de matière des flans individuels (26), le cylindre d'accélération (50a) disposant d'au moins un segment d'entraînement (53) par lequel, pendant une phase partielle de rotation du cylindre d'accélération (50a), des forces de transfert peuvent être transférées sur le flan (26), et au moins un segment libre (51, 52) aligné sur une partie gaufrée du flan (26) lorsque le flan (26) est guidé le long du cylindre d'accélération (50a) pendant une autre phase de rotation partielle du cylindre d'accélération (50a), de telle sorte que le segment libre (51) ne touche pas la partie gaufrée.
