A dispenser assembly for dispensing a sheet material, comprising: a housing comprising a discharge, and a plurality of supply rolls (26/28) of sheet material rotatably mounted therealong; a feed roller rotatably mounted along the housing and operable to facilitate dispensing of the sheet material (27/29) from the plurality of supply rolls (26/28) of sheet material along a discharge path toward and through the discharge of the housing; and a sheet material transfer assembly adjacent the feed roller in a position for selectively directing sheet materials (27/29) from the plurality of supply rolls (26/28) of sheet material into engagement with the feed roller to transfer feeding of sheet material between the plurality of supply rolls (26/28) of sheet material, the sheet material transfer assembly including a frame that is movable between a plurality of positions (102/104) including a first position that facilitates feeding of the sheet material from a first supply roll of sheet material of the plurality of supply rolls (26,28) of sheet material, and a second position that facilitates feeding or dispensing of sheet material from a second supply roll of sheet material of the plurality of supply rolls (26,28) of sheet material; wherein the frame of the sheet material transfer system moves to the second position for dispensing sheet material from the second supply roll of sheet material when the first supply roll of sheet material is substantially fully dispensed, wherein the frame comprises a plurality of roller assemblies (108/110) coupled thereto, the plurality of roller assemblies (108/110) comprising a first roller assembly having at least one roller (130/152/154) that at least partially engages sheet material from the first supply roll of sheet material, and a second roller assembly having at least one roller that at least partially engages sheet material from the second supply roll of sheet material, characterized by the dispenser assembly further comprising: a support arm positioned adjacent the first roller assembly and comprising a plurality of grooves defined therein, wherein the at least one roller (130/152/154) of the first roller assembly comprises a series of spaced projections (134/158) each having an annular surface (138/162) that at least partially engages the sheet material from the first supply roll of sheet material, and wherein when the first supply roll of sheet material is substantially fully dispensed, the series of spaced projections (134/158) are received within corresponding grooves of the plurality of grooves of the support arm positioned adjacent the first roller assembly as the frame rotates to the second position for dispensing of the second supply roll of sheet material. a housing comprising a discharge, and a plurality of supply rolls (26/28) of sheet material rotatably mounted therealong; a feed roller rotatably mounted along the housing and operable to facilitate dispensing of the sheet material (27/29) from the plurality of supply rolls (26/28) of sheet material along a discharge path toward and through the discharge of the housing; and a sheet material transfer assembly adjacent the feed roller in a position for selectively directing sheet materials (27/29) from the plurality of supply rolls (26/28) of sheet material into engagement with the feed roller to transfer feeding of sheet material between the plurality of supply rolls (26/28) of sheet material, the sheet material transfer assembly including a frame that is movable between a plurality of positions (102/104) including a first position that facilitates feeding of the sheet material from a first supply roll of sheet material of the plurality of supply rolls (26,28) of sheet material, and a second position that facilitates feeding or dispensing of sheet material from a second supply roll of sheet material of the plurality of supply rolls (26,28) of sheet material; wherein the frame of the sheet material transfer system moves to the second position for dispensing sheet material from the second supply roll of sheet material when the first supply roll of sheet material is substantially fully dispensed, wherein the frame comprises a plurality of roller assemblies (108/110) coupled thereto, the plurality of roller assemblies (108/110) comprising a first roller assembly having at least one roller (130/152/154) that at least partially engages sheet material from the first supply roll of sheet material, and a second roller assembly having at least one roller that at least partially engages sheet material from the second supply roll of sheet material, characterized by the dispenser assembly further comprising: a support arm positioned adjacent the first roller assembly and comprising a plurality of grooves defined therein, wherein the at least one roller (130/152/154) of the first roller assembly comprises a series of spaced projections (134/158) each having an annular surface (138/162) that at least partially engages the sheet material from the first supply roll of sheet material, and wherein when the first supply roll of sheet material is substantially fully dispensed, the series of spaced projections (134/158) are received within corresponding grooves of the plurality of grooves of the support arm positioned adjacent the first roller assembly as the frame rotates to the second position for dispensing of the second supply roll of sheet material.
