Analysis of influencing factors on nip width of machine calendar used in paper industry.

Machine calendaring is a finishing operation used in paper industry during which paper web is pressed between two or more steel rolls, with an objective to improve the surface properties like smoothness and gloss of the paper web. In this study an attempt has been made to develop modified nip mechanics model, which overcomes the drawbacks of existing nip mechanics models, applicable for machine calendaring in paper industry for calculating nip width. Also the effect of various calendaring parameters on nip width of machine calendar has been discussed. [ABSTRACT FROM AUTHOR]
