Abstract

L'invention concerne un dispositif de transport qui permet de transporter des feuilles en matière imprimée (01) au sein d'une machine de vernissage (03) et/ou d'impression (02) et qui comporte un organe de transport (04 ; 06) pourvu d'un moyen de circulation (05), le moyen de circulation (05) permettant d'entraîner une feuille en matière imprimée (05), par complémentarité de forme ou par friction, contre une face de butée (12) d'un dispositif de butée (09) situé en aval. Le moyen de circulation (05), lequel permet de transporter la feuille en matière imprimée (01) par complémentarité de forme ou par friction et lequel comprend un guidage et/ou un moyen d'entraînement (56), est réalisé de manière à ce qu'il soit amorti par un ressort et/ou soumis à une limitation de couple, pour ainsi assurer que le mouvement d'avance du moyen de circulation (05) bénéficie, au moins dans une partie de transport (55) coopérant avec la feuille en matière imprimée (01), d'une souplesse lorsque la feuille en matière imprimée (01) bute contre le dispositif de butée (09), augmentant ainsi la résistance par rapport au fonctionnement non-perturbée du moyen de circulation (05).
