The method for manufacturing circular knitted products can be applied in industry for the production of flexible cylindrical articles, hollow or with a core inside, for example screened electrical or optical conductors, cords, elastic cords, supporting ropes, reinforced sleeves, filters, packages etc. which have periodically changing designs and properties. The circular knitted products include a core (1) shielded with at least one warp knitted coating, made of 1 to N warp fibres (2), knitted in loops (3), connected by bows (4). The bows (4) are formed by the rotation of the warp fibres (2) around the core (1) at an angle defined by the equations: <IMAGE>where Mi denotes the number of knitted needles over jumped during the rotation, and K - small central angle of rotation. The number of the over jumped needles Mi is within the interval from N-1 to Ci. Ni where Ci is a natural number. In order to obtain irregularly situated columns of loops, around the core, the equations Mi = N-1 to Ci(N-1), and αi = 2π + K are used, where from 1 to N-1 the warp fibres (2) are excluded.<IMAGE>
