Apparatus for positioning receiving material during the application of an ink image thereto

摘要

Apparatus for keeping receiving material flat against a plate (6) during the application of an ink image thereto. The plate (6) is provided with V-shaped channels (19) which extend in the direction in which the receiving material is movable stepwise over the plate (6). Ribs (15) which separate the channels (19) from one another are provided with suction openings (20, 21) in order to draw by negative pressure bubbles, which have been formed by moisture absorption in the receiving material, into the channels (19) in order to prevent said bubbles from coming into contact there with ink application means movable flatly over the plate (6). The outermost channels (19) are provided with suction openings (27) in the channel walls (26) in order to keep wrinkles and corrugations at the sides of receiving material out of contact with the ink application means. <IMAGE>
