Base structure for a device for transporting and stretching foil, wherein the base structure comprises:

• at least one upper guide unit and a lower guide unit,
• wherein the upper guide unit is configured so as to guide at least one upper moveable rope, and the lower guide unit is configured so as to guide at least one lower movable rope,
• wherein the at least one upper movable rope and the at least one lower movable rope can be arranged so as to clamp the foil at its lateral edge at least in places and to take it along, and
• wherein the at least one upper guide unit is configured so as to push the foil by means of the at least one upper movable rope guided by the upper guide unit against the at least one lower movable rope guided by the lower guide unit,
• wherein each guide unit of the upper guide unit and the lower guide unit comprises a number of roller elements which are configured so as to guide the at least one upper movable rope and the at least one lower movable rope, respectively,
• wherein at least one roller element of the number of roller elements is arranged below the least one lower movable rope guided by the lower guide unit, and
• wherein at least one roller element of the number of roller elements is arranged at the at least one upper guide unit above the upper movable rope guided by the at least one upper guide unit,
• wherein at least two roller elements of the number of roller elements are arranged at the lower guide unit so as to clamp the at least one lower movable rope directly inbetween them against the at least one upper movable rope.
