A modular element of creel (1) including a structure (2) having at least one support (22, 23) suitable to support a reel or yarn spool (25, 26); the structure (2) is in the form of a solid polygon and includes a feeder device (30) suitable to allow the feeding of the thread developed by such spool (25, 26) with at least one characteristic, selected between the characteristics of tension and speed, maintained constant and equal to a preset fixed value or function of the operational phase of the machine, said structure (2) being able to be modularly coupled to other similar structures (2) so as to allow the feeding of more yarn to a textile machine, every yarn fed by every modular element (1) having its own selected characteristic defined by the feeder device associated with such modular element (1).
