1. A base structure for a device for a transporting film, the base structure comprising:
exactly one upper guide unit and exactly one lower guide unit, wherein
the upper guide unit is adapted to guide an upper movable rope and the lower guide unit is adapted to guide a lower movable rope, wherein
the upper moveable rope and the lower moveable rope are arrangeable to clamp and entrain the film at its side edge at least in places, and wherein
at least one of the upper guide unit and the lower guide unit is adapted to press the film via the at least one of the upper moveable rope and the lower moveable rope guided by the one of the at least one the upper guide unit and the lower guide unit against the at least one of the upper moveable rope and the lower moveable rope guided by the other one of the at least one the upper guide unit and the lower guide unit, wherein each at least one of the upper guide unit and the lower guide unit has exactly one roller element, which is adapted to guide the respective at least one of the upper moveable rope and the lower moveable rope,
wherein the exactly one roller element is arranged at the lower guide unit so as to clamp the at least one lower movable rope directly in between it and the at least one upper movable rope, and
