The method of calculation of influence of design and technological parameters of material of a cover of a packer element is developed: the initial angle of laying of threads of the reinforcing framework, the packing density of threads in the field of unions, number of layers of a framework, rubber elastic modulus on power characteristics of a cover, for the purpose of creation of edge protection of a packer element. In the first part of work the cover of a packer element with laying of threads with a constant corner on all length of a cover is investigated. The received results of calculation, allowed to evaluate and prove quantitatively the constructive and technological directions of reliability augmentation of edge protection of a packer element. The developed calculation procedure is a basis of development of more general method of calculation of power characteristics of a cover of a packer element with variable longwise covers the initial angle of laying of threads.
