ABSTRACT OF THE DISCLOSURE: An apparatus for storing and feeding yarn to yarn using machines, comprising a base plate restrainable to a stationary structure, a shaft freely rotably mounted on at least one rolling bearing carried by the base plate on one side and on the other side of which the two ends of the shaft project, a member for coupling the shaft to a motor and being rotably driven thereby, a hollow drum having a cylindrical outside surface and carried by one end of the shaft through at least one rolling bearing having its axis substantially coincident with that of the shaft. A yarn dispensing arm is positioned between the base plate and drum and is integral with the shaft. The apparatus also have a duct or channel passing therethrough, this duct or channel extending to and opening in the shaft end externally of the drum and at the adjoining cylindrical end of the drum, respectively, to distribute thereon the turns of yarn incoming through the duct or channel, a rocking body for transferring the yarn turns on the drum, this rocking body being restrained to the shaft, and members for preventing the drum from rotating on the shaft. In the apparatus the members for inhibiting the drum rotation comprise two rolling bearings with the axis thereof coincident with and parallel to but offset relative to the axis of the shaft having a single straight axis and extending through the bearings, of which one has a cage fixed to the base plate, and the other has a cage fixed to the opposing surface of the drum. A rigid connecting body for the movable cages of the bearings is mounted on the two bearings, this connecting body having a passage through which said yarn dispensing arm passes.
