A plate material tensioning and advancement mechanism is disposed in parallel relation to a cylinder (104), such as a plate cylinder of a printing press, so as to separate the plate material into distinct printable sections. The plate material tensioning and advancement mechanism (102) assists in supplying tension to the plate material (112) via a tensioning roll (114) during pointing operation and assists in winding fresh plate material about the cylinder during advancement operation by reducing the tension on the plate material and by optionally applying tangential force to the plate material via a winding roll.
Un mécanisme de tension et d'avance de matériel de plaque est disposé parallèlement à un cylindre (104), tel qu'un cylindre de plaque d'une presse d'imprimerie de manière à séparer le matériel de plaque en parties imprimables distinctes. Le mécanisme (102) de tension et d'avance du matériel de plaque contribue à appliquer une tension au matériel (112) de plaque par l'intermédiaire d'un rouleau de tension (114) pendant l'opération d'impression et il contribue à enrouler le matériel de plaque nouveau autour du cylindre pendant l'avance par réduction de la tension exercée sur le matériel de plaque et par application facultative d'une force tangentielle au matériel de plaque par l'intermédiaire d'un rouleau d'enroulement.
