COIL Russian patent published in 2022 - IPC B65H75/18 

FIELD: winding devices.

SUBSTANCE: wire coil containing a cylindrical sleeve is proposed, which includes a winding part, on which the wire can be wound, the first and the second flanges that are spaced apart in the axial direction along the sleeve and that include surfaces facing each other with a winding part located between them, the first information display sections that are formed on the surface opposite to the facing surface of the first flange and that are located on the first circle radially spaced from the center of a sleeve shaft, and at least one second information display section that is formed on the surface of the first flange and that is located on the second circle having a smaller diameter than the diameter of the first circle, around the center of the sleeve shaft. Moreover, the second information display section is shifted in a circumferential direction relatively to each of the first information display sections so that at least part of the specified second information display section is located so that a radial line passing from the specified center of the shaft and through the specified at least part of the specified second information display section does not pass through any of the specified first information display sections.

EFFECT: coil allows one to contain a lot of information to determine the type of wire without increasing the sleeve.
