Careful Pinch Roller "B" Adjustment - NEVER TIGHTEN THE LABEL ROLL HOLDER SIDE PINCH ROLLER "A"
This Video shows the Pinch Roller "B" Adjustment.
Actually this is the most important Pinch Roller of the two ; the label feed relies mostly on this pinch point. If the labels are not gripped in this Pinch assembly there may be some delay in the label feed which could contribute to the labels not being fully ejected onto the Vacuum Tamp before it moves away from the peel plate.
Pinch Roller "A" may not need to be closed at all.
Pinch Roller "A" is used mainly for webs that break easily and for higher speed applications.
In the case of the Lid Labeling the added consistency of web tension through the Gap Sensor and around the peel plate can assist in more consistent label transfer onto the Vacuum Tamp.
