Study on modeling roller squeezing semi-finished leather products

Abstract

This study is devoted to the analysis of moisture content in a two-roll module of a machine for squeezing semi-finished leather products after chrome tanning. An analytical relationship was obtained that describes the patterns of variation in moisture content during the roller pressing of semi-finished leather products; inequalities were derived for estimating the residual moisture content of semi-finished leather products. It was revealed that with a decrease in the thickness and initial moisture content of the semi-finished leather product, its moisture content decreases. It was stated that with an increase in the initial moisture content of the semi-finished leather product, its residual moisture content increases and asymptotically approaches a certain value.
