Abstract

Abstract A yarn storing device, wherein the yarn running off a bobbin can be wound tangentially onto a storing drum and can be axially removed therefrom under a retarding ring which surrounds the drum. The retarding ring comprises a base ring which surrounds the periphery of the drum at a distance and flexible, thin, elongated elements extending therefrom towards the surface of the drum. The flexible elements are formed by resilient fingers which are inclined inwards from the base ring along an imaginary conical surface and extend in the direction of relative rotation of the yarn during its withdrawal from the drum, overlap one another in the direction of the periphery and are supported by their free ends on a shoulder of the drums.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 148 words
In a yarn storing device having a storing drum adapted to have yarn wound tangentially thereon and a retarding ring surrounding the drum and adapted to have the yarn passed thereunder for removal axially from the drum, comprising the improvement wherein said retarding ring includes a base ring surrounding the periphery of the drum and spaced a small distance therefrom and a plurality of thin elongated resilient fingers extending from the base ring toward the surface of the drum, the resilient fingers being inclined inwardly from the base ring along an imaginary conical surface, said resilient fingers extending in the direction of relative rotation of the yarn during its withdrawal from the drum and disposed so as to overlap one another in the direction of the periphery of the drum, and said drum having a shoulder thereon disposed in engagement with the free ends of said resilient fingers.
Claim 2
Dependent Claim 148 words
In a yarn storing device having a storing drum adapted to have yarn wound tangentially thereon and a retarding ring surrounding the drum and adapted to have the yarn passed thereunder for removal axially from the drum, comprising the improvement wherein said retarding ring includes a base ring surrounding the periphery of the drum and spaced a small distance therefrom and a plurality of thin elongated resilient fingers extending from the base ring toward the surface of the drum, the resilient fingers being inclined inwardly from the base ring along an imaginary conical surface, said resilient fingers extending in the direction of relative rotation of the yarn during its withdrawal from the drum and disposed so as to overlap one another in the direction of the periphery of the drum, and said drum having a shoulder thereon disposed in engagement with the free ends of said resilient fingers.
Claim 3
Dependent Claim 19 words
A yarn storing device according to claim 1, wherein the resilient fingers extend in the form of a spiral.
Claim 4
Dependent Claim 39 words
A yarn storing device according to claim 1, wherein the free ends of the resilient fingers, when the resilient fingers are in a relaxed condition, lie in a circle having a radius less than the radius of the drum.
Claim 5
Dependent Claim 20 words
A yarn storing device according to claim 1, wherein the vertex angle of the imaginary conical surface is approximately 60*.
Claim 6
Dependent Claim 29 words
A yarn storing device according to claim 1, wherein said plurality of resilient fingers are spaced around the periphery of the base ring at intervals of approximately 1 centimeter.
Claim 7
Dependent Claim 21 words
A yarn storing device according to claim 1, wherein said resilient fingers have a length of approximately 1 to 2 centimeters.
Claim 8
Dependent Claim 21 words
A yarn storing device according to claim 1, wherein said resilient fingers have a width of approximately 0.5 to 1 millimeter.
Claim 9
Dependent Claim 30 words
A yarn storing device according to claim 1, wherein the base ring and the resilient fingers are constructed of plastic with said fingers being integrally connected to said base ring.
Claim 10
Dependent Claim 17 words
A yarn storing device according to claim 8, wherein the retarding ring is made of a polyamide.
Claim 11
Dependent Claim 228 words
A thread storage and delivery device for transferring a thread from a spool to a working point of a textile machine, said storage device including a storage drum having peripheral wall means onto which the thread is tangentially wound to form on said drum a thread supply, said thread being tangentiAlly wound onto said drum adjacent one axial end thereof, and retarder means disposed adjacent the other axial end of said drum for controlling the axial withdrawal of thread from said drum, said retarder means including a base ring disposed in surrounding relationship to the periphery of said drum whereby the yarn passes from said yarn supply beneath said base ring for withdrawal axially of said drum, comprising the improvement wherein said retarder means includes a plurality of thin elongated resilient fingers having one end thereof fixedly secured to said base ring, said fingers extending axially from said base ring toward said other end of said drum and being inclined relative to said base ring so that the adjacent fingers overlap one another in the direction of the periphery of the drum, said fingers being inclined and extending in the direction of relative rotation of the yarn during its withdrawal from the drum, the other ends of said fingers being free, and said drum having a shoulder thereon disposed in engagement with the free ends of said fingers.
Claim 12
Dependent Claim 228 words
A thread storage and delivery device for transferring a thread from a spool to a working point of a textile machine, said storage device including a storage drum having peripheral wall means onto which the thread is tangentially wound to form on said drum a thread supply, said thread being tangentiAlly wound onto said drum adjacent one axial end thereof, and retarder means disposed adjacent the other axial end of said drum for controlling the axial withdrawal of thread from said drum, said retarder means including a base ring disposed in surrounding relationship to the periphery of said drum whereby the yarn passes from said yarn supply beneath said base ring for withdrawal axially of said drum, comprising the improvement wherein said retarder means includes a plurality of thin elongated resilient fingers having one end thereof fixedly secured to said base ring, said fingers extending axially from said base ring toward said other end of said drum and being inclined relative to said base ring so that the adjacent fingers overlap one another in the direction of the periphery of the drum, said fingers being inclined and extending in the direction of relative rotation of the yarn during its withdrawal from the drum, the other ends of said fingers being free, and said drum having a shoulder thereon disposed in engagement with the free ends of said fingers.
Claim 13
Dependent Claim 25 words
A yarn storing device according to claim 10, wherein said resilient fingers are inclined inwardly relative to the base ring along an imaginary conical surface.
