Abstract: A frusto-conical yarn carrier of the type characterized by having a relatively small diameter end, a relatively large diameter end, an outer wall and a smooth, uninterrupted inner wall parallel to the outer wall whereby a plurality of like yarn carriers can be nested together for storage and shipment. The improvement comprises a projection such as an annular rib on one of the inner or outer wall of the cone for contacting the other of the inner or outer wall of a like yarn carrier into which the yarn carrier is nested and creating a non-parallel relationship between the adjacent walls for reducing surface contact between adjacent yarn carriers and thereby permitting easier separation from nesting relationship.
Abstract: A tubular yarn package (10) is disclosed of the type held by at least one end on a rotatably mounted plate. The plate fits into one end of package (10) and traps across the end against an inner wall of the package a length of yarn. Short length of spirally extending grooves (15) are formed in the inner wall of the package (10) adjacent to the end of the package. The yarn fits into the closest adjacent groove (15) and grips the yarn sufficiently to prevent breakage of the yarn by relative movement between the package (10) and the plate occasioned by starting or stopping the rotation of the package (10).
