Mathematical models for the distribution of hydraulic pressure in the area of squeezing leather (semi-finished leather product after chrome tanning) were developed. It was revealed that the graphs of the mathematical models obtained correspond to experimental diagrams plotted when squeezing various wet materials. From the point of view of water filtration, the roll contact zone is divided into four phases. It was established that hydraulic pressure in the first phase increases from zero to a maximum value, then in the second and third phases, it decreases from a maximum value to zero. It was revealed that the hydraulic pressure in the fourth phase, depending on the properties of the cloth used, could take negative values or be equal to zero.
