APPARATUS FOR RECEIVING TEXTILE THREADS AND THE LIKE Filed Oct. 28, 1952 l 2 Sheets-Sheet 2 United States Patent 2,723,440 APPARATUS FOR RECEIVING TEXTILE THREADS AND THE LIKE Paul Jacques Corbiere, Lyon, andPaul Froger, Ecully, France, assignors .to Socie'te Rhodiaceta, Paris, France Application October 28, 1952, Serial No. 317,274 Claims priority, application France December 13, 1951 2 Claims. 01. 23-21 The present invention relates to a method of receiving endless textilearticles such asfilaments, threads, artificial horse hairs, tows, fibre yarns, yarn assemblies, cabled yarns, webs and the like (which articleswill hereinafter for the sake of brevity be referred to as threads) delivered at any speed by any sort of spinning or winding apparatus.

Such threads are generally received on bobbins or tubes of one sort or another or on travelling belts, or in cans turning about a vertical axis at high speed, in which the articles are applied in vertical layers along the walls under the action of centrifugal force. It has also been proposed to receive them in cans rotating at low speed, in which the thread falls along a vertical line fixed in relation to the axis of the cam, this method being principally employed in the case of large textile tows resulting from operations such, for example, as combing.

In the case of relatively fine threads, such for example as those resulting from the manufacture of artificial or synthetic textiles or of yarns of any nature employed in the weaving or knitting industry, it is diflicult to introduce large quantities of such threads into a simple rotating can in the manner hitherto usual in such a way that they can be withdrawn therefrom satisfactorily, because they are deposited in coils which very rapidly collapse.

The invention relates primarily to a novel method of taking up large quantities of thread of any kind and of any thickness in a rotating container from which they can thereafter be extremely readily withdrawn without having been entangled as a result of collapsing. This method is characterised by the fact that the thread is allowed to fall freely into a container rotating at low speed, and that the line of fall of the thread and the axis of the container are moved relatively to one another.

By low speed is meant any speed at which the centrifugal force is insufiicient to move the layers of thread deposited parallel to the bottom of the container and to propel them towards the walls.

The relative movement between the line of fall of the thread and the axis of the container is produced by movement of the line of fall of the thread in such a way that the line of fall of the thread remains in one vertical plane.

The movement of the vertical line of fall of the thread may be produced by any suitable mechanical device, for example by means of gearing, or through the agency of a connecting rod, cam, eccentric, belt or the like, etc., and may be of any desired nature, either continuous or discontinuous.

Any appropriate apparatus may naturally be employed to carry into effect the method according to the invention, but it has been found that particularly good results are obtained by delivering thethread by passing it over a substantially cylindrical element which is made to oscillate transversely to its axis. Naturally the vertically .downwardly moving part of the cylindrical ele- 2,723,440 Patented .Nov. 15, 1955 2 p I ment, which defines the top end of the line. of fall of the thread into the container, must always be kept vertically above part of the mouth of the container. Preferably there are two substantially cylindrical elements, of which one carries the thread along mechanically whilst the other, turning about its axis at a peripheral velocity substantially equal to that of the thread, dispatches it downwardly into the container; in this case it is the latter element which is oscillated. I

By substantially cylindrical element is meant any smooth or fluted, embossed or grooved cylinder, as also any elements having a form similar to that of a cylinder, for example wide-angled prisms, ,squirrel cages, hyperboloids of revolution, etc.

In the various embodiments hereinbefore referred to, the element by which the thread is dispatched downwardly into the container may receive its rotational movement from a mechanical device attached to a spinning machine. It may also be loose .on its shaft and be driven by the friction of the thread. It may be situated in any desired position in relation to a device by whichthethread is mechanicallydriven.

Various forms of the method and apparatus of the present invention will now be further described by reference to the accompanying drawings wherein:

Figs. 1 and 2 show, respectively, in vertical cross-section and in plan view one form of apparatus according to the invention and Figs. 3 and 4 show, respectively, in vertical cross-section and in plan view an alternative form of apparatus.

Referring first to Figs. 1 and 2 of the drawings, the thread to be deposited is designated by 1; 2 is a mechanically driven cylinder 150 mm. in diameter, and 3 is a cylinder mm. in diameter rotating about its axis at a peripheral velocity equal to that of the thread. The container 4 is a cylindrical can having one end closed, the open end being positioned uppermost and forming a mouth to receive the thread.

The thread 1 completes a whole turn about the cylinder 2 in the direction of the arrow, whereafter it passes on to the small cylinder 3, on which it again completes a whole turn before falling freely into the can 4 turning at low speed. The base 5 rests on a circular plate 6 rotating at 5 R. P. M., the centre line of the can 4 passing through the centre of the plate 6.

The cylinder 3 is actuated with a reciprocating rectilinear movement, whereby it is displaced from 3, to 3 in the direction of the arrows, so that the thread falls into the can 4 between the extreme points 7 and 8. By reason of the rotation, the thread is distributed in all directions, giving a very permeable and readily windable mass.

In a modification of this example, the cylinder 3 is driven at higher speed than the cylinder 2, thereby increasing the speed of the thread and effecting the drawing thereof.

Figures 3 and 4 illustrate another embodiment of the method and of the apparatus according to the invention, wherein the thread 9 completes three whole turns about the assembly consisting of the

rollers

10 and 11, and then falls freely over the roller 11 into the cylindrical can 12.

The cylinder 11 reciprocates round an are between the

extreme positions

11 and 11. The vertical line of fall of the thread is shifted on the transverse section of the can along a radius between the

extreme points

13 and 14 and is coiled in the form of wide convolutions which can very readily be wound.

Naturally, any arrangement other than those indicated in the foregoing may be provided to produce the required displacement of the line of fall of the thread, which is the essential feature of the method.

By means of the devices and the method according to the invention, it is possible to obtain perfectly homogeneous and windable masses of threads in containers of any form, notably cylinders, prisms, cones, pyramids or frusta thereof.

The containers in which the textile articles are received may be perforated at any desired point and these receptacles may thus directly serve for various treatments, such as recovery of solvent by means of a liquid or gas, bleaching, dyeing, etc. It is possible, for example, to dye the threads without withdrawing them from the container by employing a container in which the lateral walls are perforated and by circulating a dye solution by means of a pump through the perforations in the container.

The method and apparatus according to the invention have been found particularly useful for receiving the artificial or synthetic threads leaving spinning frames (viscose, acetate, cuprammonium rayon, superpolyamides, poly-esters, poly-urethanes, or vinyl or acrylic polymers etc.), but they may also be advantageously employed to receive threads, yarns, yarn assemblies, etc., consisting of or containing natural fibres.

Apparatus for depositing thread in a container comprising means for rotating the container at low speed, means for feeding the thread downwardly into the container including a substantially cylindrical element over which the thread is passed, and means for oscillating the substantially cylindrical element transversely to its axis so that the vertically downwardly moving part thereof is always vertically above part of the mouth of the container.

2.
