What is Direct Paper?

Direct paper stacking refers to the removal of the static paper on the transfer table by the roller's tooth decay. The paper speed needs to rise from zero to the surface speed of the printing cylinder in an instant, and it is easy to slip in the cavities, causing transmission errors, and even severely tearing the edges of the paper. In addition, in order to hold the paper directly from the delivery table, the roll reduction teeth must be enlarged to 120 ^. Right and left, the time to close the teeth is very short. Generally, a "hit latch" device is used, which has a large impact, affects the stability of the paper positioning, and easily damages the machine. Therefore, this method is not suitable for high-speed printers, and the printing speed is limited to 3000 ~ 4000 sheets / hour. ^[1]
