Abstract
Abstract A thread is wound in successive loops at the same end of a stationary holder having an even number of rollers arranged in a circle. Alternate rollers rotate in opposite directions to reduce friction. A rotary thread guide builds up a coil on the rollers from which the leading loop is taken off and supplied to a textile machine, while new trailing loops are laid by the rotary thread guide. When the number of loops of the wound coil is sufficient, the motor driving the thread guide is stopped, and then started again when a minimum number of loops remains on the rollers.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
144 words
Thread-storing device for temporarily storing a thread supplied to a textile machine, comprising holding means having a main axis and including supporting means, and at least a pair of holding members mounted on said supporting means for angular movement in opposite directions about two axes spaced from said main axis; drive means for angularly moving said holding members; winding means at one end of said holding means and including a thread guide rotatable about said main axis for winding a supplied thread at said one end about said angularly moving holding members so that wound loops slide on said holding members in one axial direction from said one end of said holding means toward the other end of the same; and takeoff means adapted to be operated by the textile machine for unwinding from said holding members the loop leading in said axial direction.
Claim 2
Dependent Claim
144 words
Thread-storing device for temporarily storing a thread supplied to a textile machine, comprising holding means having a main axis and including supporting means, and at least a pair of holding members mounted on said supporting means for angular movement in opposite directions about two axes spaced from said main axis; drive means for angularly moving said holding members; winding means at one end of said holding means and including a thread guide rotatable about said main axis for winding a supplied thread at said one end about said angularly moving holding members so that wound loops slide on said holding members in one axial direction from said one end of said holding means toward the other end of the same; and takeoff means adapted to be operated by the textile machine for unwinding from said holding members the loop leading in said axial direction.
Claim 3
Dependent Claim
18 words
Thread-storing device as claimed in claim 1 wherein said drive means rotate said holding members in opposite directions.
Claim 4
Dependent Claim
31 words
Thread-storing device as claimed in claim 1 wherein said supporting means include at least two parallel shafts; and wherein said holding members are elongated tubular rollers mounted on said shafts, respectively.
Claim 5
Dependent Claim
44 words
Thread-storing device as claimed in claim 1 wherein said drive means include motor means, and transmission means connecting said motor means with said holding members for rotating the same; wherein said motor means are connected with said winding means for rotating said thread guide.
Claim 6
Dependent Claim
61 words
Thread-storing device as claimed in claim 4 wherein said motor means is mounted at said other end of said holding means on said supporting means, and includes a hollow shaft extending along said main axis, and being connected with said winding means for rotating said thread guide; and wherein the thread is supplied to said thread guide through said hollow shaft.
Claim 7
Dependent Claim
49 words
Thread-storing device as claimed in claim 5 wherein said winding means includes a disc secured to said hollow shaft and having a peripheral bore axially extending through said disc and constituting said thread guide, said bore being spaced from said main axis a greater distance than said holding members.
Claim 8
Dependent Claim
52 words
Thread-storing device as claimed in claim 6 wherein said disc has a peripheral flange axially projecting in said one axial direction and circumferentially extending about said one end of said holding means and of the corresponding ends of said holding members; and wherein said axially extending bore is formed in said flange.
Claim 9
Dependent Claim
60 words
Thread-storing device as claimed in claim 1 wherein said two axes are parallel to said main axis and spaced the same radial distance from said main axis; and wherein said thread guide is radially spaced from said main axis a greater distance than said radial distance so that said thread guide moves along a circular path about said holding members.
Claim 10
Dependent Claim
81 words
Thread-storing device as claimed in claim 1 wherein said holding means comprise at least another pair of holding members so that an even number of holding members is provided, all said holding members having axes located equally spaced along a circle having the center thereof in said main axis and being parallel to the same; wherein said driving means include motor means, gear means driven by said motor means, and a gear on each holding member driven by said gear means.
Claim 11
Dependent Claim
39 words
Thread-storing device as claimed in claim 9 wherein said supporting means include a housing in which said gear means and said gears are located, and a plurality of shafts secured to said housing and rotatably supporting said holding members.
Claim 12
Dependent Claim
123 words
Thread-storing device as claimed in claim 1 wherein said supporting means include at least two shafts having said two axes, respectively, and wherein said holding members are tubular rollers mounted on said two shafts, respectively, said tubular rollers and shafts having free ends located in the region of said one end of sAid holding means, said free end of each tubular roller having a starting surface having a diameter gradually reduced in said one axial direction and merging into the remaining outer surface of said tubular roller; and wherein said thread guide moves along a circular path about said starting surfaces of said tubular rollers so that the wound loops slide from the same to the remaining outer surfaces of said tubular rollers.
Claim 13
Dependent Claim
64 words
Thread-storing device as claimed in claim 1 wherein said winding means includes a disc having a circular peripheral outer rim having an axial bore therethrough forming said thread guide; wherein said disc is connected with said drive means and rotated by the same; and wherein the thread taken from said leading loop by said takeoff means slides along said peripheral outer rim without rotating.
Claim 14
Dependent Claim
93 words
Thread-storing device as claimed in claim 1 wherein said winding means and thread guide are rotated by said drive means; further comprising a plate guided for axial movement along said holding members resting on said leading loop and moving toward said other end of said holding means with said leading loop when said winding means winds more thread loops on holding members than are taken off by said takeoff means, and moving toward said one end of said holding means when more thread is taken off than is wound on said holding members.
Claim 15
Dependent Claim
62 words
Thread-storing device as claimed in claim 13 wherein said drive means include motor means having a start switch and a stop switch on said supporting means spaced in axial direction; and wherein said plate operates said start switch and stop switch, respectively, in two end positions in which a minimum and a maximum, respectively, of loops is wound on said holding members.
Claim 16
Dependent Claim
33 words
Thread-storing device as claimed in claim 14 wherein said start and stop switches are magnetic switches; and wherein said plate includes a permanent magnet for actuating said magnetic switches in said end positions.
Claim 17
Dependent Claim
69 words
Thread-storing device as claimed in claim 1 wherein said drive means also drive said winding means and thread guide; and further comprising means for stopping said drive means when a predetermined number of loops has been wound on said holding members, and for again starting said drive means when a predetermined number of loops has been unwound and taken off said holding members while said drive means is stopped.
Claim 18
Dependent Claim
