Date Apr. 24, 1986.A dispenser for dispensing a web downwardly from a vertically arranged tubular roll of the web provides for preventing unwanted dispensing of the web under the influence of gravity. Each unwanted dispensing is achieved by applying a restraining force to an appropriate location on the roll or on the web, the force being of a magnitude such that the web is restrained against unwinding by gravity yet the web can be pulled downwardly from the roll without tearing. The restraining force can be applied in any of several ways including applying a strip of adhesive tape to one end of the roll, pressing a groove into one end of the roll, applying adhesive spots at spaced intervals along the web before it is wound into a roll or by providing a mechanical arm or the like which presses against the periphery of the roll.</p> |
