in the elevated position.
1. Adjust the rear film plates close to the tube, forming an
even gap. DO NOT clamp the film to the tube.
2. Verify all fasteners are tightened.
There are four finger guides that may be used or may be moved out of
the way via slots - See Figure 6:
Using or not using the finger guides is a judgment made for each setup.
All, none, or some of the fingers may be used to modify the behavior of
the film as it travels down the tube. For example, all four fingers may
be used to evenly pull the film into the corners or they may selectively
be used to pull the film into corners where the seals are too narrow.

1. Move the guides toward the corner made by the forming
tube and the forming tube "wings" - See Figure 7:
