Abstract
Abstract A textile yarn carrier comprising a core having a yarnsupporting surface and a yarn-receiving groove disposed in the supporting surface and extending at least partially around the core and a yarn catch insert mounted within the groove for facilitating starting of the winding of a package of yarn. Preferably, the insert comprises a base, a plurality of barbs extending outwardly from the base at an acute angle upwardly of the groove and engaging the core for securing the insert within the groove and a plurality of yarn-catching fingers extending outwardly from the base at an acute angle downwardly further within the groove to define a yarn pinch area between the base and each of the yarn-catching fingers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A textile yarn carrier for use in winding yarn packages, said carrier comprising an elongate core including a yarn-supporting surface having a yarn-receiving groove generally V-shaped in transverse cross section disposed in said supporting surface and extending at least partially around said core, and a yarn catch insert mounted within said groove for catching the yarn to facilitate the starting of the winding of a package, said insert comprising a generally V-shaped base wedged within said groove, a plurality of barbs extending outwardly from the outside of said V-shaped base at an acute angle upwardly of said groove and engaging said core for securing said insert within said groove and a plurality of yarn-catching fingers extending outwardly from the inside of said V-shaped base at an acute angle downwardly further within said base to define a yarn pinch area between the inside of said V-shaped base and each of said fingers.
Claim 2
Dependent Claim
151 words
A textile yarn carrier for use in winding yarn packages, said carrier comprising an elongate core including a yarn-supporting surface having a yarn-receiving groove generally V-shaped in transverse cross section disposed in said supporting surface and extending at least partially around said core, and a yarn catch insert mounted within said groove for catching the yarn to facilitate the starting of the winding of a package, said insert comprising a generally V-shaped base wedged within said groove, a plurality of barbs extending outwardly from the outside of said V-shaped base at an acute angle upwardly of said groove and engaging said core for securing said insert within said groove and a plurality of yarn-catching fingers extending outwardly from the inside of said V-shaped base at an acute angle downwardly further within said base to define a yarn pinch area between the inside of said V-shaped base and each of said fingers.
Claim 3
Dependent Claim
114 words
A textile yarn carrier for use in winding yarn packages, said carrier comprising: an elongate core having a yarn-supporting surface and a yarn-receiving groove disposed in said supporting surface and extending at least partially around said core; yarn catch insert means having a base secured within said groove to said core and a plurality of yarn-catching fingers extending outwardly from said base and terminating within said groove for frictionally engaging and grasping the yarn as it is brought within said groove; and at least some of said yarn-catching fingers extending outwardly from said base and downwardly further within said groove to define a yarn pinch area between said base and each of said fingers.
Claim 4
Dependent Claim
114 words
A textile yarn carrier for use in winding yarn packages, said carrier comprising: an elongate core having a yarn-supporting surface and a yarn-receiving groove disposed in said supporting surface and extending at least partially around said core; yarn catch insert means having a base secured within said groove to said core and a plurality of yarn-catching fingers extending outwardly from said base and terminating within said groove for frictionally engaging and grasping the yarn as it is brought within said groove; and at least some of said yarn-catching fingers extending outwardly from said base and downwardly further within said groove to define a yarn pinch area between said base and each of said fingers.
Claim 5
Dependent Claim
53 words
The textile yarn carrier of claim 2 wherein said groove is generally V-shaped in transverse cross section; and said yarn catch insert means including a plurality of barbs extending outwardly from said base at an acute angle and upwardly of said groove and engaging said core for mounting said insert within said groove.
Claim 6
Dependent Claim
72 words
The textile yarn carrier of claim 2 wherein said groove is generally V-shaped in transverse cross section; said base being generally V-shaped and wedged and held within said groove; and said plurality of yarn-catching fingers extend outwardly from the inside of said V-shaped base at an acute angle downwardly further within said V-shaped base to define a yarn pinch area between the inside of said V-shaped base and each of said fingers.
