The handbook outlines the , demonstrating how tension relates directly to strain and material elasticity: σ=E⋅ϵsigma equals cap E center dot epsilon = Stress (Tension per unit area) = Modulus of Elasticity (Young's Modulus) = Strain (Deformation ratio)
: How different webs (paper, foil, etc.) behave under stress.
If you are looking to solve a specific machine issue, let me know: What are you running (film, paper, foil)?

To control a web, rollers must maintain traction. High speeds can introduce an air boundary layer that lifts the web off the roller, causing a loss of traction (floating). The handbook outlines the , demonstrating how tension
Reducing the winding tension as the roll grows in diameter to prevent the outer layers from crushing the inner layers.
Search for the Second Edition if possible. The first edition (published 1986) is still brilliant for mechanical concepts but lacks modern updates on tension sensors and AC vector drives. The second edition (2000s) and the third (2016) include critical updates on elastic-plastic webs.
Rewinding a roll with too much tightness, causing the layers to stick together permanently. : For a simplified overview of these principles,
