Abstract
An inexpensive unit for removable attachment to the spindle of a roll holder for a roll-type paper product such as toilet tissue or paper towelling. The unit is formed from a flexible plastics material and includes a center section having an arcuate bight portion and a pair of wall portions that converge from the arcuate portion and are joined together along the end edges thereof. An arm extends laterally from each end of the joined end edges of the walls. The unit is slid onto a spindle and when a roll of paper material is in turn slid onto the unit-carrying spindle the joined end edges of the walls will forcefully engage the inner surface of the roll core. When a user pulls the free end of the paper material wound on the roll the unit of this invention will rotate with the roll until the laterally extending arms engage or abut the edges of the roll holder. This signals the user that an appropriate length of material has been pulled from the roll and that that length may now be torn from the roll. If more material is required the user continues to pull on the free end of the paper material, causing the arms to flex inwardly and to be drawn through the roll holder until they emerge…
