5. The infeed assembly of claim 4 , wherein, for each of the first cylinder assembly and the second cylinder assembly, the first position of the first bar and the second bar corresponds to a de-energized position of the air cylinder and the second position corresponds to an energized position of the air cylinder.
6. The infeed assembly of claim 4 , wherein in the second position of the first bar and the second bar of the first cylinder assembly the first bar engages a first roller of the first roller assembly and the second bar engages a second roller of the first roller assembly.
7. The infeed assembly of claim 6 , wherein the second position of the first bar and the second bar of the first cylinder assembly corresponds to a queued position of the first web, wherein the first web is pinched between the first bar of the first cylinder assembly and the first roller of the first roller assembly and between the second bar of the first cylinder assembly and the second roller of the first roller assembly.
8. The infeed assembly of claim 7 , wherein a respective first roller assembly and second roller assembly is moveable with a respective first cylinder assembly and second cylinder assembly from the idle position to the operative position adjacent the conveyor assembly with the respective one of the first web and the second web in the queued position.
9. The infeed assembly of claim 7 , further comprising pins that protrude between the first roller and the second roller of the first roller assembly in the idle position of the first roller assembly.
10. The infeed assembly of claim 9 , further comprising pins that protrude between the first roller and the second roller of the second roller assembly in the idle position of the second roller assembly.
11. The infeed assembly of claim 10 , wherein in each of first roller assembly and second roller assembly the pins engage respective openings in the respective first web and second web in the queued position.
12. The infeed assembly of claim 6 , wherein in the second position of the first bar and the second bar of the second cylinder assembly the first bar engages a first roller of the second roller assembly and the second bar engages a second roller of the second roller assembly.
13. The infeed assembly of claim 12 , wherein the second position of the first bar and the second bar of the first cylinder assembly corresponds to a queued position of the first web in which the first web is pinched between the first bar of the first cylinder assembly and the first roller of the first roller assembly and between the second bar of the first cylinder assembly and the second roller of the first roller assembly, wherein the second position of the first bar and the second bar of the second cylinder assembly corresponds to a queued position of the second web in which the first web is pinched between the first bar of the second cylinder assembly and the first roller of the second roller assembly and between the second bar of the second cylinder assembly and the second roller of the second roller assembly.
14. An infeed assembly for feeding a web to a continuously operating machine comprising a first reel carrying a first web and a second reel carrying a second web, a first guide assembly associated with the first reel and a second guide assembly associated with the second reel, each of the first guide assembly and the second guide assembly comprising a queuing member configured to queue the end portion of a respective one of the first web and the second web in position to be loaded into the machine while the other web is being used by the machine, wherein, for each of the first guide assembly and the second guide assembly, the queuing member is a roller assembly cooperating with pins that hold the respective first web and second web in a predetermined position, and wherein the end portion of the respective one of the first web and the second web is placed on the pins of the respective first guide assembly and the second guide assembly when the end portion of the respective one of the first web and the second web is queued.
