Clutch Roller Adjustment
The one-way clutch roller assures that the tape does not go backwards any time during
dispensing, further more it is a tool in achieving correct front tape leg length.
Different quality tapes have different adhesives and release coats. This has an effect on the
dispensing, e.g. very “sticky” tapes are peeling-off with higher resistance, so they will need
minimal tension on the clutch roller. Tapes that unwind easily may need more tension on the
clutch roller to achieve uniform front tape leg length during sealing.
Main Spring Adjustment
1.) To decrease the clutch roller’s tension, turn the
M6 friction nut at the end of roller
counterclockwise, it requires a 10 mm wrench. Do
not loosen to the point that the roller could be
moved laterally on the shaft.
2.) To increase the clutch roller’s tension one needs
to turn the M6 friction nut clockwise. Make tiny
increments (less than eighths of a turn) at a time
and check the sealing results before going any
further. Once the disc spring has been over
squeezed it may lose its properties. To avoid this
eventuality, pay attention.
The main spring retainers are set at the factory for the most common applications. The top tape head
will need lighter springs, UPH0910 or UPH0911, while the bottom positioned tape head will need
heavier springs, UPH1091.
The ET-X 3-inch tape heads can run up to 140 ft/min line speed, the 2-inch version up to 150 ft/min
line speed. In applications one might have normal cases, over filled cases, void filled cases, flimsy
corrugated boxes, stiff double fluted cases. The speed and the nature of the box will determine the
best main spring setting. Typically, the higher the line speed the more tension one requires from the
main spring. To increase the rollers’ pressure we have the following techniques to choose from in
order of ease:
Option 1:
If one needs a little bit more (~15%) pressure
on the application rollers and have a stainless
steel spring mounted on the tape head, may
change the spring for the music wire version.

bottom tape head)
