Abstract: A separator holder structure for the quick loading of yarn would spools in dyeing machines, drying machines or other processing devices. The structure consists of a frame forming latticed tray which is divided internally into housings in each of which is secured, with the possibility of a limited vertical movement, a separator adapted to keep the yarn wound spools centered within the respective housing and to ensure hydraulic tightness between the vertically stacked elements in each column of spools when multiple structures are stacked. The possibility of movement of ht eseparators permits a quick stacking of the spools on horizontal layers, as the expedient allows the correct setting of separators, in individually loose manner, to ensure hydraulic tightness of same at the two ends of spools on which the yarn is wound.
