Abstract
Abstract A thread delivery and, if necessary, storage device, preferably for textile machines and particularly for elastic threads to be used therewith. A coil member is provided to which a thread is continuously fed, moved axially, and then continuously removed tangentially. Rollers are arranged around the shaft of the coil member, each of said rollers being rotatable around its own axis and one thereof being driven. The axis of one of the rollers is pivotally mounted and normally slightly tilted, relative to the axis of the coil member both to effect the axial movement of the thread and to effect the desired control. The amount of thread wound on the coil member, and its axial location, determines the pivotal position of the tilted roller, and the passing of said tilted roller in one direction or the other of a given tilted position operates a switch or other control means to bring about the desired control over the operation of a driving motor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
216 words
In a thread delivery and, if necessary, storage apparatus, preferably for textile machines and in particular for elastic thread, said apparatus having coil means defining a longitudinally extending axis and to which a thread can be fed tangentially and on which thread windings can be transported axially, said coil means including a stationary support member and a plurality of rollers mounted thereon for rotation about their respective axes, the axes of said rollers extending in a direction approximately parallel with the longitudinal axis of said coil means, at least one of the rollers being drivable and the axis of at least one of the rollers being tilted tangentially relative to said longitudinal axis, drive means operatively interconnected to the drivable roller for driving same, and control means for controlling said drive means in dependence upon the amount of thread stored on the coil means, the improvement comprising mounting means coacting with one of said rollers for permitting swinging movement of said roller in a direction at least radially relative to the longitudinal axis of said coil means, swingable movement of said swingable roller being caused by the thread windings wound on the coil means, and said control means being operatively connected to said swingable roller, whereby swinging movement of said swingable roller controls said control means.
Claim 2
Dependent Claim
216 words
In a thread delivery and, if necessary, storage apparatus, preferably for textile machines and in particular for elastic thread, said apparatus having coil means defining a longitudinally extending axis and to which a thread can be fed tangentially and on which thread windings can be transported axially, said coil means including a stationary support member and a plurality of rollers mounted thereon for rotation about their respective axes, the axes of said rollers extending in a direction approximately parallel with the longitudinal axis of said coil means, at least one of the rollers being drivable and the axis of at least one of the rollers being tilted tangentially relative to said longitudinal axis, drive means operatively interconnected to the drivable roller for driving same, and control means for controlling said drive means in dependence upon the amount of thread stored on the coil means, the improvement comprising mounting means coacting with one of said rollers for permitting swinging movement of said roller in a direction at least radially relative to the longitudinal axis of said coil means, swingable movement of said swingable roller being caused by the thread windings wound on the coil means, and said control means being operatively connected to said swingable roller, whereby swinging movement of said swingable roller controls said control means.
Claim 3
Dependent Claim
56 words
An apparatus according to claim 1, further including guide means associated with said swingable roller for controlling the swinging movement thereof for causing a variation in the tangential position of one of said rollers in response to radial movement of said swingable roller for balancing the axial feed of the thread winding along the coil means.
Claim 4
Dependent Claim
36 words
An apparatus according to claim 2, wherein said guide means causes a tangential displacement of said one roller relative to the longitudinal axis of said coil means in response to radial displacement of said swingable roller.
Claim 5
Dependent Claim
40 words
An apparatus according to claim 2, wherein said guide means causes both a radial and a tangential displAcement of said swingable roller for balancing the effect of movement of said swingable roller on the axial feed of the thread windings.
Claim 6
Dependent Claim
78 words
An apparatus according to claim 1, wherein the thread is tangentially fed onto the coil means adjacent one axial end thereof and is withdrawn from the coil means adjacent the other axial end thereof, one end of said swingable roller being swingably supported by said mounting means adjacent said one end of said coil means, and the other end of said swingable roller being disposed adjacent the other end of said coil means and being freely radially swingable.
Claim 7
Dependent Claim
65 words
An apparatus according to claim 5, further including guide means associated with the other end of said swingable roller for simultaneously causing both radial and tangential displacement thereof, said guide means including a projection secured to one of said swingable roller and said support member, said guide means further including an elongated recess formed in the other of said swingable roller and said support member.
Claim 8
Dependent Claim
28 words
An apparatus according to claim 3, wherein said guide means causes the circumference of said coil means to remain substantially constant when said swingable roller is radially displaced.
Claim 9
Dependent Claim
72 words
An apparatus according to claim 1, wherein said coil means includes a disk member disposed adjacent the withdrawal end of said coil means, said disk member having a radially projecting bulge, and said drive means being drivingly connected to said disk member for causing rotation thereof in the same direction as said rollers, whereby said disk member guides the withdrawal end of the thread by means of friction around the coil means.
Claim 10
Dependent Claim
32 words
An apparatus according to claim 8, further including a brake ring disposed adjacent the withdrawal end of said coil means for controlling the withdrawal speed of the thread from the coil means.
Claim 11
Dependent Claim
19 words
An apparatus according to claim 9, wherein the brake ring is arranged on and rotates with the disk member.
Claim 12
Dependent Claim
40 words
An apparatus according to claim 10, wherein said drive means is interconnected to said disk member for causing rotation thereof at a speed whereby the peripheral speed of the brake ring is greater than the peripheral speed of the rollers.
Claim 13
Dependent Claim
128 words
An apparatus according to claim 1, wherein said coil means includes a pair of spaced, stationary support members fixedly interconnected by a central shaft extending therebetween, said central shaft defining the longitudinal axis of said coil means, and said plurality of rollers being substantially uniformly spaced around said shaft and extending between and being rotatably supported on said first and second support members, one end of said swingable roller being pivotally connected adjacent one support member, the other end of said swingable roller as disposed adjacent the other support member being freely radially swingable relative to said central shaft, and said control means including switch means operatively interconnected to said one end of said swingable roller for actuation thereby in response to swinging movement of said swingable roller.
