Abstract
A manual dispenser of material of indeterminate length, which is engaged on a rotating roller assembly, such that when the end of the material is pulled, the roller rotates with the material until reaching a stop, whereafter by slipping, additional material is advanced a length suitable to the user. The material is then forced to sever against a cutter, creating a useful material segment, and also releasing the roller assembly to rotate backwards, powered by a biasing spring. Upon return, the roller holds the remnant end of the material extended, readily accessible for grasping. An alternate embodiment comprises a movable cutter.
