48892947, Dec 26, 1989

Filed:

Nov 17, 1988

Appl. No.:

7/272735

Inventors:

Samuel F. Adams - Greenville SC
Hans-Peter Bolz - Greenville SC

Assignee:

Sonoco Products Company - Hartsville SC

International Classification:

B65H 7510

US Classification:

2421183

Abstract:

This invention is directed to a yarn carrier with means for visually indicating the type of yarn wound onto the carrier. In particular the indicator is a color coded ring which is received in a channel at the end of the yarn carrier. This arrangement provides a clear visible indication of the type of yarn on the carrier while not adding to the length or diameter of the carrier. As such the critical dimensions of the carrier are assured while providing a simple convenient indication of the type of yarn.

International Classification:

B65H 7510
B65H 7518

US Classification:

24211831

Abstract:

This invention relates to a lightweight plastic yarn carrier adapted to receive yarn wound thereon to form a yarn package. The yarn carrier is comprised of a hollow conical tube with a reinforced end portion at one end of the tube. The end is formed of an annular end wall extending radially in from the end of the tube and an annular flange extending inwardly toward the opposite end of the tube from the inner periphery of the end wall. The peripheral wall, end wall and annular flange collectively define an inside annular channel within the carrier. The reinforcement of the end portion is comprised of a plurality of circumferentially spaced apart ribs extending across the inside annular channel and at least one circumferential rim extending from the end wall and circumferentially around the inside annular channel to reinforce the end portion of the carrier. With this reinforcement arrangement, the end wall better resists impact on the end and further prevents the spread of damage that may be incurred.

International Classification:

B65H 7510

US Classification:

24211831

Abstract:

A carrier for textile yarn characterized by a construction designed to prevent undesirable sloughing-off or migration of the yarn during winding and unwinding and to reduce the amount of material needed to construct the carrier while retaining desired crush strength includes generally the following. An elongate hollow body having a transverse circular cross-section defines an outside surface of consecutive stepped portions extending around the body along the length of the carrier for defining a saw-toothed longitudinal configuration and yarn carrier areas which prevent undesirable sloughing-off or migration of the textile yarn during winding and unwinding. The inside surface of the body also includes somewhat similar consecutive stepped portions for cooperating with the outside surface to reduce the amount of material needed to construct the carrier while retaining a surface to fit the spindle of a textile machine. Opposing stepped portions of the outside and inside surfaces are positioned in a generally longitudinally staggered relationship for defining transverse portions in the body of the same radial thickness as would be present if the outside and inside surfaces were of a smooth unstepped configuration to provide reinforcement and crush strength to the carrier.

International Classification:

D06B 2304

US Classification:

68189

Abstract:

A plastic spacer ring for spacing apart and sealing plastic dye tubes during yarn package dyeing. Each plastic spacer ring has an annular groove on both its upper and lower surface for receiving an end face of a dye tube. Each groove has an open top and a closed bottom with the width of the open top greater than, and the width at the closed bottom less than the predetermined wall thickness of the plastic dye tube body. This construction provides tangential contact between the end faces of the plastic dye tubes on both side walls of the annular groove, which in turn, provides two seals substantially continuously about the circumference of the end face of the dye tube.

B65H 4926

US Classification:

242 18DD

Abstract:

A textile yarn carrier adapted to receive a yarn tail at the base thereof without breaking the yarn tail. The yarn carrier includes a body having an outer face about which yarn may be wrapped, an inner face, and an annular face at its bottom end. A plurality of adjacent, circumferentially oriented, semielliptical depressions are formed in the bottom face of the yarn carrier. Each depression extends from the outer face, radially across the bottom face, and upwardly along and into the inner face. In the preferred embodiment, the depressions are uniform in size and are spaced generally evenly around the periphery of the body, so that the bottom and inner faces of the yarn carrier are adapted to guide and receive a yarn tail in at least one yarn protecting depression on each side of the body. An end holder cap for mating with the bottom end of the textile yarn carrier is also provided. The end holder cap has an annular flange for contacting the bottom face of the yarn carrier at a plurality of points intermediate each semielliptical depression, and a resilient circumferential face for engaging the inner face of the carrier at a plurality of points intermediate each depression.

US Classification:

2421251

Abstract:

This invention relates to a yarn carrier with means for catching the end of a yarn and also for providing an identification of a particular characteristic of the yarn. The catching and identifying means comprises a radially extending opening through the peripheral wall of the yarn carrier arranged to receive a color coded insert. The combination of the insert and the opening additionally form oppositely directed yarn engaging notches for catching and retaining the free end of the yarn to be wound on the carrier.

International Classification:

B65H 7526

US Classification:

2421183

Abstract:

A universal yarn carrier is disclosed which is adapted to have an advancing yarn effectively wound thereon, when used on either a P-wind or a Q-wind machine. The yarn carrier comprises a molded plastic tube having an external cylindrical surface, and at least one yarn catching means integrally formed on the exterior surface adjacent one end thereof. The yarn catching means is adapted to catch and anchor one or more of the initial yarn windings so as to prevent axial slippage thereof, and the yarn catching means comprises an annular depression, and an extension extending in the longitudinal direction across a portion of the depression so as to define a tip at the free end of the extension for engaging the yarn being wound upon the carrier.
