Claims
- 1. A tubular paper yarn carrier for carrying a yarn strand wound thereon, comprising:
(a) a carrier wall defining an inner wall surface and an outer wall surface on opposite sides thereof, one end of the carrier wall defining a top and an opposed end of the carrier wall defining a base; and (b) an annular lip formed on a terminal portion of the base and extending outwardly therefrom for strengthening the base and preventing slippage of the yarn strand off of the base of the carrier.
- 2. A yarn carrier according to claim 1, wherein said inner wall surface defines an inner diameter of the carrier, and said outer wall defines an outer diameter of the carrier, wherein said outer diameter has a value of X and said inner diameter has a value of (0.95)X or less.
- 3. A yarn carrier according to claim 2, wherein said outer diameter defined by said outer wall surface has a value of X and said annular lip includes an outermost edge defining a diameter having a value of (1.02)X or greater.
- 4. A yarn carrier according to claim 1, further comprising an annular nose formed on the inner wall surface proximate the top of the carrier, said annular nose having an outermost edge defining a diameter less than a diameter defined by the inner wall surface for nesting in the base of a like yarn carrier.
- 5. A yarn carrier according to claim 1, wherein said carrier is cylindrical.
- 6. A yarn carrier according to claim 1, wherein said carrier is frusto-conical.
- 7. A stackable tubular paper yarn carrier assembly comprising a first carrier comprising:
(a) a carrier wall defining an inner wall surface and an outer wall surface on opposite sides thereof, one end of the carrier wall defining a top and an opposed end of the carrier wall defining a base; (b) an annular lip formed on a terminal portion of the base and extending outwardly therefrom for strengthening the base and preventing slippage of the yarn strand off of the base of the carrier; and (c) an annular nose formed on the inner wall surface proximate the top, said nose having an innermost edge defining a diameter less than a diameter defined by the inner wall surface for nesting of a second yarn carrier.
- 8. A stackable yarn carrier assembly according to claim 7, further comprising a divider positioned proximate the junction between said first and second carriers for separating yarn strands wound thereon.
- 9. A tubular paper yarn carrier for carrying a yarn strand wound thereon, comprising:
(a) a carrier wall defining an inner wall surface and an outer wall surface on opposite sides thereof, one end of the carrier wall defining a top and an opposed end of the carrier wall defining a base; and (b) an annular lip formed on a terminal portion of the base and extending outwardly therefrom for strengthening the base and preventing slippage of the yarn strand off of the base of the carrier, wherein said annular lip is formed by positioning the terminal portion of the base into a lip shaped void defined by a rotating tool to form said annular lip.
- 10. A tubular paper yarn carrier according to claim 9, further comprising an annular nose formed on the inner wall surface proximate the top of the carrier by positioning a terminal portion of the top of the carrier in a nose shaped void defined by a second rotating tool to force the terminal portion inward to form said annular nose having an outermost edge defining a diameter less than a diameter defined by the inner wall surface for nesting in the base of a like yarn carrier.
- 11. A method for making a tubular paper yarn carrier having an annular lip for preventing slippage of a yarn strand wound thereon, comprising the steps of:
(a) providing a tubular paper yarn carrier wall defining an inner wall surface and an outer wall surface on opposite sides thereof, one end of the carrier wall defining a top and an opposed end of the carrier wall defining a base; (b) providing a rotating tool having a void corresponding to a desired shape for a terminal portion of said base; (c) positioning the terminal portion of said base in the void of the rotating tool to form an integrally formed annular lip extending outwardly from the terminal portion of the base.
- 12. A method for making a tubular yarn carrier including an annular nose having an outermost edge defining a diameter less than a diameter defined by an inner wall surface of the carrier for nesting of a like yarn carrier, comprising the steps of:
(a) providing a carrier wall defining an inner wall surface and an outer wall surface on opposite sides thereof, one end of the carrier wall defining a top and an opposed end of the carrier wall defining a base, and an annular nose formed on the inner wall proximate a terminal portion of the top; (b) providing a rotating tool having a void corresponding to a desired shape for the terminal portion of the top; (c) positioning the terminal portion of the top in the void of the rotating tool to force the terminal portion inward to form an annular nose having an outermost edge defining a diameter less than a diameter defined by the inner wall surface.
- 13. A method for making a tubular yarn carrier including an annular nose having an outermost edge defining a diameter less than a diameter defined by an inner wall surface of the carrier for nesting of a like yarn carrier, comprising the steps of:
(a) providing a carrier wall defining an inner wall surface and an outer wall surface on opposite sides thereof, one end of the carrier wall defining a top and an opposed end of the carrier wall defining a base, and an annular nose formed on the inner wall proximate a terminal portion of the top; (b) providing a rotating disc having an outer edge for contacting the carrier; (c) positioning a plug into the top end of the carrier; (d) contacting the terminal portion of the top end of the carrier with the rotating disc and moving the disc along the top end of the carrier to urge the annular nose inward until the annular nose contacts the plug, whereby the annular nose has an outermost edge defining a diameter less than a diameter defined by the inner wall surface of the carrier.
- 14. A method for making a tubular yarn carrier according to claim 13, wherein the plug defines a predetermined diameter corresponding to a predetermined diameter of the outermost edge of the annular nose.
