Roll Grooving Tips with 960
1. If pipe tends to "walk off" drive roll, clean drive roll and
increase offset dimension (Figure 6).
2. If cover plate shaves pipe end, decrease offset
dimension.
3. If pipe end flare is excessive, lower pipe end to level
with roll groover.
4. If pipe wobbles and/or "walks off" the drive roll, raise
pipe end to level with Roll Groover.
5. Short lengths of pipe (under three feet) may require
slight pressure to maintain the
dimension.
6. DO NOT attempt roll groove 1" stainless steel pipe.
May cause damage to the groover.
