Why a Lateral Tension Balancing Roller Is Installed After Unwinding
Anyone working with coil or web processing lines will be familiar with the phenomenon of tight-loose-edge in rolled strip. This is fundamentally caused by transverse tension differential across the web width. During production, non-uniformity does not only originate at the die or extrusion head. As the material travels over rollers under tension, any misalignment between…

Why winding always with loose-tight-edge?
In the web material production industry, there has long been a nightmare-like issue – the tight/loose edge of material rolls. That is, after the winding process is completed, one end of the roll is wound too tightly while the other end is wound too loosely. This discrepancy causes the overly tight end to continuously compress…

Numerical Balance Roller
For corrugated production line professionals, everyone dreams of a line that’s both faster and higher-performing. In reality, however, the ultimate purpose of a corrugated line is to produce qualified board. This board comes from the base paper, and the components that are in direct contact with the paper are the rollers. No matter how robust…
