ABSTRACT:
A wrinkle-preventing mechanism for a high-speed printer, in which the web constituting the printing medium passes between skewed image and pressure cylinders while being subjected thereby to a high pressure, includes a flat-surfaced, rigid pressure pad underlying the web path toward the nip of the cylinders, a skewed, freely rotatable, elastomer-surfaced drag-inducing roller for pressing the web over its entire width against the pressure pad, and a loading system for applying forces to the roller to provide the requisite loading across the entire width of the web. A skew angle for the drag-inducing roller of about 2.degree.-5.degree. relative to the perpendicular to the direction of movement of the web toward the nip is preferred.
