F.6.2 Force Calculation when the Web is not Centered on the Roll
Use the calculations below for horizontal and inclined mounting when the web is not centered
on the roll.
The applied force at the load cell will be proportional to the distance between the tension force
center and the load cell centerline.
Calculation procedure:
1.
Horizontal or inclined mounting?
2.
Calculate F
R
and
F
RT
, see
3.
Use the following equations:
F
R
for single load cell =
F
RT
for single load cell =
F
Rtot
for single load cell = F
R
for single load cell + F
RT
for single load cell
where:
L
= Distance between load cell centerline and the opposite bearing centerline
a
= Distance between tare force center and load cell centerline
b
= Distance between tension force center and load cell centerline
