ABSTRACT:
In a stencil printer including a rotatable drum for wrapping a perforated stencil or master therearound, a pair o f inclined tension rollers are movable into and out of contact with the drum in order to smooth a creased master. The distance between the tension rollers sequentially increases from the upstream side toward the downstream side with respect to an intended direction of master transport. While the master is sequentially wrapped around the drum, the tension rollers pull the opposite side edges of the master outward. At the same time, the elastic member presses the intermediate portion of the master. The tension rollers and elastic member cooperate to smooth the master. The elastic member is located at a position not closer to the drum than a position around a line connecting the points of the tension rollers contacting the master, and where it can contact the intermediate portion of the master.
