THE MECHANICS OF TENSION CONTROL

Each tension zone is very unique and must be controlled independently. Since independent tension controls are used in each zone, each zone may have its own tension level. This means, for example, tension in the unwind zone may be 1 PLI then increase to 2 PLI in the internal zone then decrease to 1.5 PLI in the rewind zone.

Force testing | Mecmesin

Force testing is a way of determining how an object will react when it is subjected to tensile or compressive loads - either during its normal operation or when being pulled/pushed until it deliberately fails or breaks. These forces can be classified as tension, compression, flexure, shear and fracture. When delivered suddenly at ultra-high speed this is known broadly as …
