The following relates to fabric calenders, both textile and steel cord only.
Localized cord disturbance in cord distribution does not usually affect fabric weight, whereas overall cord distribution problems can affect fabric weight, sheet gauge, and quality.

A consistent feed to the calender will substantially reduce gauge variations. Consistent, uniform, dwell times on the break down and feed mills, as well as consistent bank size, will result in consistent
stock temperatures, work history, and reduced variations in roll separating forces.
The stock temperatures, bank sizes, and work history all directly influence roll-separating forces. Minimizing variations in these 3 important process parameters will minimize variations in roll separating forces, and this in turn will minimize gauge variations. Good mill and bank control practice also results in improved uniformity for other final calendered gum and/or fabric properties. Read more…
