Winding Tension
Definition
Pull force during winding, affecting flatness and performance.
Historical Background
1980s: tension control systems achieved precise constant-tension winding.
Example
Too loose: wrinkles; too tight: deformation. Like rolling sushi.
Formula
Winding Tension (N) = Substrate Thickness (um) x Width (mm) x Tension Coefficient
Core Concepts
Ensures flat uniform layers with real-time adjustment.
Extended Applications
Film: low; paper: medium; cloth: high; thick: graduated; elastic: low+braking.
