3) Adjust the balance between the front and the rear:
4) If the median value of the measured nip is toward
the lower limit of the standard, tighten the screw on
the side with a lower nip value at the edge.
MEMO:
A 1/2 turn of the screw shifts the nip balance by about
0.4 mm.
A 1/2 turn on the screw at the front will increase the
nip at the front by 0.3 mm, decreasing the nip at the
rear by 0.2 mm.
If the median value of the measured nip is toward the
higher limit of the standard, tighten the screw on the
side with a higher nip value at the edge.
If the nip needs adjustment while the nip balance is
correct, the adjusting screw both at the front and rear
may be given a 1/2 turn so that the nip may change by
about 0.3 mm.
