Abstract: The invention relates to a film store and method for dynamically storing a strip-like label film, wherein the film store comprises at least one storage region with an upper carriage and a lower carriage as well as deflection rollers fastened thereto for the label film. The label film is guided along a transport path extending in a meandering manner between the upper carriage and the lower carriage, and the size of the film store is adjusted by the upper and lower carriage moving in opposite directions while mutually compensating for weight. Because the upper carriage and the lower carriage are moved toward one another or away from one another by a torque-controlled or force-controlled servo motor and/or the servo motor tensions the label film between the deflection rollers, the storage dynamics and the storage capacity can be optimized while maintaining a maximum permissible strip tension in the label film.
