An infeed station comprises an eccentric roller fitted between two rotary plates around which a web-like material travels so as to have its running speed transformed from a constant inlet speed into an outlet speed which varies according to predetermined conditions in the course of an operating cycle of the station, as well as an infeed roller which guides the web-like matter from the eccentric roller towards a platen. The infeed roller is driven by an independent device so that the peripheral speed follows conditions similar to the outlet speed of the web-like matter although remaining permanently at a higher rate of speed.
Un poste d'alimentation comprend un rouleau excentrique posé entre deux plaques tournantes autour desquelles passe un matériau en bande continue de façon que sa vitesse d'avancement se transforme d'une vitesse d'entrée constante en une vitesse de sortie qui varie selon des conditions prédéterminées dans le cours du cycle d'opération du poste, ainsi qu'un rouleau d'alimentation qui guide la matière en bande continue du rouleau excentrique à un plateau. Le rouleau d'alimentation est entraîné par un dispositif indépendant, de sorte que la vitesse périphérique suit des conditions similaires à la vitesse de sortie de la matière en bande continue, bien que demeurant en permanence à un niveau de vitesse plus élevé.
