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. The trigger device is operably connected to the guide member so as to move the guide member to the operating position upon the trigger device moving to the trigger position.
