ABSTRACT:
A strip media tensioning system is set forth for imposing drag on a moving band such as a circulating endless belt for driving reel packs for delivery of magnetic tape therebetween. More particularly, an apparatus is set forth which includes a fixed shaft. A sleeve is journalled for rotation about the shaft, the endless belt engaging and rotating the sleeve. To create drag, a visco-elastic ring is positioned between the shaft and sleeve and is compressed against the sleeve creating drag by an eccentrically disposed roller device. The eccentricity of the roller device is adjustable for altering the drag on the circulating endless belt.
