The wire and felt guide unit for steady guidance of the wire and low
maintenance costs-no unplanned shutdowns, highest reliability due to
uniform and rapid response, lowest maintenance costs.
Example of installation: wire and felt guide unit installed in a 1,800 m/min.
tissue machine at Corelex Shin-Ei Paper, Japan.
Andritz wire and felt guide unit that enables reliable wire tracking.
Conventional mechanical tracking systems comprise many parts,
which require a lot of maintenance and perform a machine directional movement that is failure-prone. A reliable, well functioning
wire tracking system is crucial for ensuring trouble-free operation.
The wire and felt guide unit enables precise control due to pneumatic
design. It features a pivoting saddle to which the bearing housing of
the wire tracking roll is bolted. The saddle is pivoted by two reciprocal air bellows (one constant pressure, the other variable), resulting
in a skewed position of the guide roll. The guide centers the wire by a
finely proportioned air flow into the controlling air bellow.
applications are the driver, customer need is our focus. This is quite to
the contrary of available solutions, which are promoting digitalization
as the primary focus. Customer need is profitable production, with
quality, productivity, and sustainability constraints. Our products in
this segment already deployed at pulp and paper mills provide information to mill staff where it is needed, and are able to steer processes
well ahead of substantial hiccups due to prediction capabilities derived
out of data analytics.
The customer's challenge is to find a service partner who understands the customer's equipment, processes, and procedures and
knows the complete production process and the factors of influence.
There are many "maintenance" companies; unfortunately, many of
these companies do not understand the unique processes, equipment
demands, and safety requirements of a paper mill. Based on its longterm experience and tradition as a paper machine supplier, Andritz
helps-from replacement parts to comprehensive service programs
-protect and extend the life of equipment and lower life cycle costs.
Is the use of digitization, Big Data, and aspects of Industry 4.0
coming into the service division of Andritz? And what are the
challenges a modern mill faces?
Andritz is already preparing the basic data and tools for future implementation in new service products, and we are already gaining experience from the first automation installations of tissue machines. Our
focus is to approach Industry 4.0 from a technology-enabling and
lifetime-prolonging standpoint. Digitalization is the vehicle, smart
