The leather industry includes many technological machines; a squeezing roller machine is used in many operations, for example, in squeezing, degreasing, and after drum dyeing of a semi-finished leather product.

The paper presents the results of experimental studies obtained by determining the influence of multilayer wet leather semi-finished products with monshons under squeezing on the amount of the moisture extracted. Mathematical dependences of the amount of the moisture extracted, for each layer of a five-layer wet leather semi-finished product on the feed rate between the squeeze rollers and the roller pressure were obtained.

Experimental research is of scientific and practical importance for the development of a technological process for extracting moisture from wet leather semi-finished products used in the tannery, since the quality of the extraction affects the quality of subsequent technological operations, such as leather shaping and splitting.

An experimental study was performed using the method of mathematical statistics, namely, the method of mathematical planning of the experiment.

Mathematical models were obtained for the amount of extracted moisture from five wet leather semi-finished products depending on the rate of their simultaneous feed and the pressure of the squeezing rollers.

The results of the experiment showed that in squeezing a five-layer product, the productivity of the technological process of extracting moisture from wet leather semi-finished products increases by five times in comparison with existing squeezing roller machines.

The use of the results of the experimental study will contribute to a significant reduction in the energy consumption of the squeezing roller machine by simultaneous multi-layer processing of wet leather semi-finished products
