Helpful coating tips: jet angle, gap, critical factors, etc.

Factors that increase coat weight: decrease of blade load, decrease tip angle, increased viscosity/solids, increase speeds & increase in sheet roughness.

The mechanism, need for and effect of reel drum grooving

As machine speed increases and sheet porosity decreases grooving of the reel drum becomes necessary in order to avoid sheet wrinkles, sheet breaks and quality defects.
