seamless integration of an inspection system
into any production process – and ideally
into nonwovens manufacturing lines –
detecting holes, irregularities, contamination
and any other defect. The installation is easy
and flexible: a fixture bar bridges the full
width of the process line holding as many
spectroscopes as required for the
application. The sophisticated
spectroscopes offering best monitoring

optimal defect detection in combination with
the spectroscopes, various light sources are
integrated in the installation – all customized
and perfectly suited to mill light conditions.
The system may be slim and compact, but it
delivers big-value benefits for the operator.
USTER EVS FABRIQ VISION N provides
