Importance of effective web transport
The web transport test rig uses the rewinder principle and comprises unwinding, measurement/testing, and winding sections. It allows defined processing conditions to be set. Controlled unwinding comes after a controlled dancing roller system in the form of a web buffer. Selecting the tension of the buffer allows the winding of the web to be performed under defined winding tension.
In the measurement/testing section, the processing and measurement of the web tension / web tension profile are performed. Testing different machine components is made possible by the flexible web transport, separate drive system, and large assembly space.
