Web dispenser

An apparatus for selectively dispensing a web of serrated bags from a plurality of rolls of serrated bags, each roll of bags having a series of bags connected by transverse perforations, the apparatus comprising a web selector adapted to select and advance a web of serrated bags from the plurality of rolls of serrated bags;

• a bag driver adapted to advance the selected web of serrated bags and separate a first bag from an adjacent second bag along a serration connecting the first and second bags;
• and a bag transfer device adapted to transport the separated first bag from the bag driver to a location for further processing;
• wherein the web selector comprises:
• a) a first and second stationary drive roll spaced apart from one another;
• b) a center moveable roll disposed between and spaced apart from the first and second stationary drive rolls;
• and
• c) a mechanism for selectively moving the center moveable roll toward the first and second stationary drive rolls respectively;
• d) a first outer moveable roll spaced apart from the first stationary drive roll;
• and
• e) a second outer moveable roll spaced apart from the second stationary drive roll;
• f) a mechanism for selectively moving the first outer moveable roll toward the first stationary drive roll;
• and
• g) a mechanism for selectively moving the second outer moveable roll toward the second stationary drive roll;
• wherein the center moveable roll and the first stationary drive roll are adapted to accommodate a first web of serrated bags disposed between the center moveable roll and the first stationary drive roll, and to selectively nip the first web of serrated bags between the center moveable roll and the first stationary drive roll;
• the center moveable roll and the second stationary drive roll are adapted to accommodate a second web of serrated bags disposed between the center moveable roll and the second stationary drive roll, and to selectively nip the second web of serrated bags between the center moveable roll and the second stationary drive roll;
• the first outer moveable roll and the first stationary drive roll are adapted to accommodate a third web of serrated bags disposed between the first outer moveable roll and the first stationary drive roll, and to selectively nip the third web of serrated bags between the first outer moveable roll and the first stationary drive roll;
• and
• the second outer moveable roll and the second stationary drive roll are adapted to accommodate a fourth web of serrated bags disposed between the second outer moveable roll and the second stationary drive roll, and to selectively nip the fourth web of serrated bags between the second outer moveable roll and the second stationary drive roll.
