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.
A dispenser for a material web, particularly a paper web, comprising a tubular roll of the web, the roll having an axis about which the web is wound, an upper end face, a lower end face, an inner side and an outer side, and a holder for supporting the roll with its axis substantially vertical, the holder having an opening therethrough which is located at a lower surface of the dispenser directly adjacent the lower end face of the tubular roll, said web having a free end depending from inside the roll at the lower end face thereof and being unwindable from the inner side of the roll in a downward direction through the opening, the weight of said free end causing a tendency for the web to unwind by gravity;
A dispenser for a material web, particularly a paper web, comprising a tubular roll of the web, the roll having a length dimension and a width dimension, a holder for supporting the roll with its length dimension substantially vertical, said holder including a horizontal bottom wall having an opening therein which is only slightly smaller than the cross-section of the roll of the web, and the roll being supported by the bottom wall only at the periphery of the roll, said web having a free end depending from inside the roll at the lower end face thereof through said opening and being unwindable from the inner side of the roll in a downward direction through the opening, the weight of said free end causing a tendency for the web to unwind by gravity;
