(FR) PROCEDE ET DISPOSITIF POUR COMMANDER LE DEFILEMENT D"UNE NAPPE DANS UNE MACHINE D"IMPRESSION
Abstract: front page image
(EN)The web is advanced during each cycle, alternatively at the printing speed during printing and at an intake speed at the most equal to the printing speed, while reabsorbing through a return of the web the excess in length provided by the printing speed with respect to the intake speed if the latter is slower than the printing speed, without stopping the web. A typical device comprises downstream of the printing cylinder (2), a first endless rotary member for driving the web at the printing speed (9) and a second endless rotary member (12) for driving the web at the intake speed. Application to papers in webs of a great variety of weights and qualities.
