Abstract
The article provided the experimental pressing of moisture leather semifinished products after chrome tanning was conducted in combination with fibrous materials put between them. The technological process of pressing a semifinished leather product to the bend on the base plate along the vertical plane between the roller pair is considered. The regularity of the pressure change between the squeezing rolls during the processing of semifinished leather on the stand of a vertical roller machine is studied experimentally. Bend on the base plate, the factors acting on the processed material in the contact zone with the roller pair of the roller machine for processing leather are investigated. The experimental studies were conducted on a specially designed and manufactured stand using modern electronic measuring equipment aimed to apply the results in further theoretical calculations. The methods of mathematical statistics were used to process experimental results. The mathematical dependences of the amount of liquid removed for each semifinished leather product on the feeding speed and the pressing force of the pressing rollers were obtained. The use of the results obtained will increase the productivity of the technological process of extracting moisture from the leather semifinished product, taking into account its physical and mechanical properties. The results of the experiment can be used in design, research, and development institutions and at enterprises of the leather industry.
