Textile Wherever running web products are manufactured,
processed or finished, two factors are critical for
the quality of the finished product: constant
tension and the consistent lateral position of the
web. FMS closed loop control systems for web
tension and web guiding continually maintain
all the relevant parameters to ensure precise
compliance with the reference values. At the
same time, these values are made available
for comprehensive recording for quality
assurance purposes.

FMS Web Tension
Measurement The web tension in the
material (FB) causes a
resulting force in the
direction of the bisecting
line (FM) on a wrapped
roller. The measurement
of this force is a direct
measure of the web tension.
The feedback value can
be sent to an FMS closed
loop tension controller,
which regulates a drive,
brake, or clutch, ensuring
constant material tension
throughout the process.
FMS Web Guiding The actual position of
the web is detected by
a sensor. The web guide
controller compares the
measured position value
with the pre-set reference
value and controls the
drive of a steering frame.
The steering frame ensures
a stable web position by
pivoting the steering frame
rollers to guide the material.
