1. A system for cutting a metallic film comprising:
a scoring blade;
a scoring blade actuator operatively connected to the scoring blade for actuating the scoring blade;
an anvil in alignment with the scoring blade;
a first conveyor disposed upstream of the scoring blade and the anvil;
a second conveyor disposed downstream of the scoring blade and the anvil, the first and second conveyors operating at a first speed;
a metallic film feeder for feeding the metallic film on the first conveyor, the first conveyor feeding the metallic film between the scoring blade and the anvil, the second conveyor pulling the metallic film from between the scoring blade and the anvil;
a first protective film feeder for feeding a first protective film between the metallic film and the scoring blade;
a second protective film feeder for feeding a second protective film between the metallic film and the anvil,
the scoring blade actuator being operable to move the scoring blade toward the anvil to apply a pressure onto the first protective film, the metallic film, and the second protective film disposed between the scoring blade and the anvil for making a score along a width of the first protective film,
the pressure applied not cutting the metallic film, the first protective film and the second protective film; and
a third conveyor disposed downstream of the second conveyor, the second conveyor feeding the metallic films to the third conveyor, the third conveyor operating at a second speed, the second speed being greater than the first speed, a difference between the first and second speeds causing the metallic film to cut at the score.
