The purpose of this work is the elucidation of the behavior of Cauchy-type integrals near the boundary semicylindrical domain to θ(δ)- characteristics celebrated jordanovic of closed curves (in the case when θ(δ)~δ, this class of curves is much wider class of piecewise-smooth class of curves for which the chord length relation to the pulling together arch are limited (K-curves), and also in it existence of cusps is allowed). The main characteristics for functions f∈C_∆ - the mixed and private modules of continuity which was proven continuously extendibility of n-multiple Cauchy-type integral to the border of the semicylindrical domain and the limit values of the types of Sokhoskiy’s formulas.
