The appearance of new types of polymer gratings on the market, which have other functional and technical-operational indicators, raises the question of new kinematic solutions to their work. In this paper, questions of parametric optimization of the functioning of this type of sieves from the angle of their origin and kinematic sieves are considered. We have carried out a system analysis of existing technological schemes of lattice mills and identified promising areas of modernization.
