Abstract
A dispenser apparatus includes a loading device for sensing when an initial working roll of web material previously positioned in a receptacle is empty, so that it can be replaced with a fresh second roll positioned between a pair of flanges. The loading device includes a first mechanism fixed within a hinged cover of the apparatus including a movable tab in a position substantially opposite the point where the material web is inserted and placed on a drum. The device further includes a second mechanism extending from the apparatus housing which is activated when the cover is closed to sense when the initial roll is empty and to control the actuation of the mechanism to load the web from the fresh second roll.
Claims10
A paper dispenser for dispensing metered amounts of a paper web material, said dispenser comprising:
- a casing including a hinged front cover and a pair of support flanges perpendicularly disposed relative to a casing backwall;
- a rotatable drum;
- an integral cutting device, said cutting device and said drum being installed crosswise in a bottom part of said casing between said support flanges, said drum being rotated by traction of paper web material;
- a hold-down element fitted over said rotatable drum, wherein the part of said casing is slotted to enable the paper web material to pass therethrough, said casing including a receptacle in the rear of the lower part thereof sized for retaining a first service paper roll and a second reserve paper roll supported by a pair of flanges in an upper part of said casing;
- a loading system designed to test for depletion of the first paper roll placed in said receptacle so as to switch to said second paper roll located between said upper flanges,
- said loading system including a primary mechanism mounted inside said cover in a position substantially facing a paper band from the first paper roll as the band passes and is run onto the drum to cut said band, and a secondary mechanism mounted to said dispenser casing, said secondary mechanism including a member which is engaged by the closing of said cover into a position which tests for the depletion of said first paper roll to cause said primary mechanism on the cover to feed a band of paper from the second paper roll onto the drum;
- wherein the paper band of the nearly depleted first paper roll disposed in said receptacle placed on the drum is stretched and constitutes a guard area adjacent to a profiled plate placed crosswise behind said rotatable drum, said paper band being disposed to cooperate with said secondary mechanism of said loading system, said profiled plate including a hole for receiving said member of said secondary mechanism when the cover is closed.
