Abstract (en)
[origin: EP0987597A1] Between inlet (140) and outlet (150) of storage area, weighting device (120,160) presses film material band to pull it tight. When film length in area changes due to change in tension and dead weight, weighting device height is changed by coupling with turn (A,B) of off-drive link (310) of direction switched coupling (300). Coupling drive (320) is turned in free-wheel direction at preset speed. Height of lower roller (120) indicates amount of film band still in storage area.
