ABSTRACT:
A dispenser for a roll of stretch-wrap film enables the operator to apply variable tension to the end of the unwinding film. The dispenser has a spindle the end of which forms a hub which attaches securely to the core of the film roll, and rotates with the roll as the film is unwound. The spindle extends coaxially from the core of the film roll and is partially surrounded by a flexible hand grip. Bearings are coaxially mounted on the spindle and interposed beneath part of the hand grip, so that the spindle may rotate freely with respect to the hand grip. Part of the hand grip engages the spindle without interposition of bearings, so that the application of radial hand pressure results in frictional braking torque on the unwinding film roll, which enables tension to be applied to the end of the film.
