  • Patent number: 6145779
    Abstract: A dual roll dispenser includes a housing having first and second roll retaining devices for holding at least two rolls within the housing. A feed mechanism is disposed in the housing to dispense material from the first roll and second roll in a sequential feeding operation. A guide member is disposed within the housing and is movable between a staging position spaced from the feed mechanism and an operating position wherein the guide member contacts and moves material from the second roll to a dispensing nip of the feed mechanism for subsequent dispensing of material from the second roll upon the first roll being depleted to a predetermined degree. A movable trigger device is disposed against the outer circumferential surface of the first roll and moves in a path as the first roll is reduced in diameter upon depletion thereof. When the first roll is depleted to a certain diameter, the trigger device passes beyond and out of contact with the first roll into a trigger position.
