ABSTRACT:
A conical yarn carrier comprises yarn supporting surfaces in the form of longitudinal rods which are held together by securing rings to form a cage having a circular cross section. Radially extending openings and longitudinally extending slots or channels are provided between the rods. These slots or channels extend lengthwise between adjacent yarn carrier rods and approximately from the middle of the yarn carrier axially to its upper edge and overlap with said openings. The yarn carrier further comprises a ring element located on the carrier surface forming rod. The ring element is axially displaceable within certain limits and comprises radially inwardly extending projections guided in the slots or channels.
