Page 17
Cause
The tape is threaded incorrectly
The tape tension is too low
The knurled roller drags
Tape tracks to one side or drags 
on the support tabs of applying 
frame
The one-way tension roller is not 
correctly positioned
Taping head is not set up properly
The blade is dull and/or has 
broken teeth
Tape tension is insu  cient
Adhesive has built up on blade 
The blade is not positioned 
properly
The blade is dry
The blade is in backwards
One or both cutter springs are 
missing or stretched
Tension roller surface is not fully 
contacting the taping head frame
Correction
The tape must go around the 
wrap roller before going around 
the one-way tension roller
Adjust the one-way tension roller
Check for adhesive build-up 
between the knurled roller and its 
shaft.  Clean and lubricate shaft.  
Remove all lubricant from roller 
surfaces.
Adjust the tape web alignments
Position the roller in its mounting 
slot so that the tape extends just 
beyond the centerline of the 
applying roller
Check leg length adjustments
Replace the blade 
Increase tape tension by adjusting 
the one-way tension roller
Clean and adjust the blade 
Make sure the blade is bottomed 
out against the mounting bolts
Lubricate the blade oiler pad on 
the blade guard
Mount the blade so that the 
beveled edge is away from the 
entrance of the head
Replace the defective spring(s)
Make sure one-way bearing is 
below the surface of the tension 
roller.  If not, press bearing further 
into roller or replace roller.
