Tensioning devices and guides

The SensoTension P felt tensioning system provides constant and reliable press felt tension. It gives the felt a longer service life and prevents vibrations and measurement failures. With the SensoTension P, a novel tensioning carriage replaces the old carriage and allows perfect movement and sliding in the guide, eliminating vibrations and wear. An optional measurement with a load cell guarantees reliable and exact measurement, resulting in constant felt tension. All main components of the SensoTension P are made of stainless steel to prevent corrosion.

Constantly rising productivity and quality requirements lead to higher demands on fabric and web run, as well as on the dryer fabric tension. Reliable fabric tensioning systems are therefore increasingly gaining significance.

In conventional fabric tensioning systems, the measurement point is directly integrated in the tensioning device, which often leads to vibrations and contamination. SensoTension DE ensures exact and reliable dryer fabric tensioning through separation of the tensioning and tension measurement functions.

SensoTension LC measures the exact tension of clothing in the wire, press and dryer section. Control signals are present to directly guide the tensioning device and therefore ensure constant belt tension.

Unlike conventional belt force sensors, SensoTension LC is dual-channel in its design and thus ensures a constant tension for your paper machine. Due to the continuous comparison of both signals, reliable and stable functioning is ensured and a disproportionate deviation can be detected at an early stage.

SensoTension LC is suitable for horizontal as well as inclined installation situations in the forming, press and dryer sections.

LoadCell Pro measures the exact tension of clothing in the wire, press and dryer section. Control signals are present to directly guide the tensioning device and therefore ensure constant belt tension.

Unlike conventional belt force sensors, LoadCell Pro is dual-channel (redundant) in its design and thus ensures a constant tension for your paper machine. Due to the continuous comparison of both signals, reliable and stable functioning is ensured and a disproportionate deviation can be detected at an early stage.

LoadCell Pro is suitable for all installation positions in the forming, press and dryer section and is even suitable for hanging positions.

The HDU Guide is the optimum control unit for all machines that have an endless clothing run. A spring-compensated servo cylinder in the HDU Guide moves the roll with a pivoting movement on one side and thus controls the clothing run. The movement through a pivot point causes low wear and low maintenance. The HDU Guide with roll can be moved manually or by motor in the machine direction to compensate for a one-sided band run due to misaligned rolls.

The HDU control system upgrade includes replacement of the pendulum sensor and pneumatic controls in older belt-guiding systems. Clothing wear can therefore be reduced. Instead of replacing the entire guide system, a less expensive option is to replace the pendulum sensor with the relevant pneumatic controls in an HDU control system upgrade.

The run-out alarm from Voith ensures that the fabrics or press felts cause no damage in case of a failure of the fabric run control.

The reliable alert system is a contactless monitoring of the fabric position in cross direction to the machine. Therefore, one unit will be placed on the tender side and one on the drive side. For maximum safety, switches are present in each unit for the alert and for the shutdown.

The run-out alarm can be used in the forming, press and dryer sections of tissue, board and paper machines.
