摘要

The machine has card retention and delivery arrangements suitable for holding the cards (10) along their edges and two horizontally rotatable, mutually parallel cylindrical screens (7) which rotate in opposite directions on opposite sides of the card. The screens are rotated under control of an electronic regulation and monitoring arrangement with a detection device for the arriving card to be printed. The regulation and monitoring arrangement controls systems (8) which turn the screens at a rate corresponding to the speed of motion of the cards.
