In the presented part of work the case with the angle of laying variable longwise of the reinforcing threads of a packer element in median and edge zones is investigated. Calculation of power characteristics of a cover of a packer element with various slopes is carried out. Tests of natural prototypes of covers the packer ele-ments are carried out. The calculation results compared with data of an experiment are presented in the form of schedules with good degree of convergence. The developed technique allows to choose an optimum design of covers of a packer element with higher value of rigidity on face sites that ensures reliable functioning of a packer element at pressure differences in annular space.
