Description

The invention relates to a device for winding and forwarding thread-like structures. The device is particularly applicable in the production of rayon threads, in such a way that the thread-like structure is received at one point of the device and, after a number of turns, runs off again at another point, offset in the axial direction Device, the thread-like structure can be subjected to the usual aftertreatment or mechanical processing, on the device itself or between several devices.
Bar drums are already known for a similar purpose, which either consist of two groups of drum segments built into one another or of fixed drum disks

ao arranged rods and movably guided further between such drum disks There are rods on which the thread .selbsttätig continuous sideways in a helical line is promoted, the thread undergoes a treatment, in particular with chemicals.

Such drums, which have double-acting control grooves and a differential gear, Compression springs, etc. rods to move the drum work, bring along difficulties in the production also disruptions during operation, since the drum bars and the control grooves experience severe and inevitable wear.

Other known devices in turn, in the form of long cage drums, work with groups of hollow, square shaped guide bars, two discs on each Front side of the cage drums, a common axis of rotation made up of several by universal joints interconnected parts and other elements of intricate design. As I said, these devices are very complicated; their parts are therefore also soon subject to wear, which means that these devices can be used for a longer period of time as well as an advantageous work in the production of artificial silk is not possible are.

In relation to the known devices, it is the object of the invention to provide a simple one and cheap to produce and reliable in their operation device for winding and forwarding thread-like structures, especially during manufacture of rayon threads, to be created in a continuous process, which can also be used in place of the rayon sp hone machines used guide rollers or through installation also where previously worked without guide rollers can be used. The device according to the invention is also for

various other purposes, which will be given later, for example, ver reversible.

The device according to the invention be * consists of two unilaterally mounted, on their facing inner surfaces with axial Directional fixed guide rods occupied rotatable discs with offset from one another and axes of rotation that intersect outside the disks ίο, one of which is inclined to the horizontal, the guide rods of the one disc are passed through appropriately offset slots or recesses in the other disc. So there are no more drums required with the subject of the invention movable or slidable guide bars, but only two discs with fixed guide bars. Here, in a manner known per se, an adaptation to the elongation or shrinkage of the thread-like structure can be achieved the position or the surface design of the guide bars in the simplest way be effected.

The offset angle of the disk axis center lines can expediently be changed be so that the threadline in the size of its lateral migration and also the Can regulate thread tension. The device according to the invention is required due to its small size and simplicity their work equipment only requires little space or space. This makes it possible to have several and even numerous such Winding and forwarding devices with great variability to work together in the position and position of the devices.

In the drawing, the device according to the invention is for example, in particular at their use in the artificial silk technique. Show it:

Fig. Ι a pair of discs with axially directed guide bars in side view, Fig. 2 is a view corresponding to Fig. Ι 90 ⁰ rotated,

Fig. 3 is an end view of the pair of discs according to Fig. 1,

Fig. 4 is a side view of only one disc with specially designed thread licking rods to automatically drop the thread and

Fig. 5 is a schematic representation of an arrangement of devices according to "FIG Invention in the aftertreatment z. B. of rayon threads in view.

In Fig. Ι, d ^{1 is} the shaft of a disk g ¹

with guide bars I ¹ and a ~ the shaft of a disk g ² with guide bars / ³ .

From Figs. 1 and 2 it can be seen that the cantilevered shafts a ¹ and a ^{2 of} the

Discs g ^{· 1} and ^{g 2} do not run parallel to one another in their longitudinal direction and, moreover, as can be seen in particular from FIG. 3, are arranged with their center lines · m ^{1 and} m ² offset to one another. f VHence, ie if the shaft " ¹ horizontal" and the shaft a ^{2 is} inclined to the horizontal and the center lines m ^v and m ^{2 of} the disk shafts are offset, there is a kind of double eccentricity of the disks g ¹ and g ² to each other. The latter has the consequence that if the disks with their shafts α ¹ and a ^{2 are set} in rotation using individual drives or a common drive, then the guide rods I ¹ and I of the mutually inclined disks execute axial and radial movements against each other whereby, for example, a thread structure running up at Z with appropriate eccentricity and inclination of the disks to one another, approximately offset by at least one thread size, runs around the guide rods and along them in the form of a helix and runs again more or less soon at A in the direction of the arrow.

To effect this operation, no further machine parts complicated type are in the apparatus of the invention result 9 <> conducive, as even a mere adjustment of the bearings for the shafts' ¹ and a? is sufficient to change and adjust the offset angle of the disc axis center lines and thus to regulate the thread path.

The discs can also be stored in such a way that the shaft of one disc in the then hollow shaft of the other disk is embedded, of course with preservation the necessary inclination of the shaft '<> <' axes and while maintaining the above-mentioned Eccentricity. Both shafts can be rotated in this form by a common drive element. The mode of action is the same as in the previously described type of storage. The only difference is then the fact that the drive does not come from both sides, but only from one end he follows. ""

With appropriate use of the agents contained in the invention, i. on the basis of the type and shape described, there is now also the Possibility of a regulation in addition to causing the axial displacement of the thread and to bring about adjustment of the thread tension and elongation, in a manner known per se by a corresponding one Design of the outer surface of the guide rods as well as by changing the offset angle the disc axis center

lines, whereby the means mentioned can of course be used as desired.

In the embodiment according to Fig. 4, the thread guide rods are at their free Ends at s like a knife towards the inside of the jacket formed by the guide rods beveled inwards. It turned out that the running thread, especially when it is damp, stick it lightly to the flat faces of the guide bars can and is not thrown off freely, that is, when the device rotates rapidly can be taken and then not recorded in time by the machine operator becomes, which leads to congestion of the draining material, disruptions of the work process and similar abuses result, but this is due to the inward-looking ones in this case Bevelling of the free ends of the guide rod is prevented.

In Fig. S, for example, is an arrangement of devices according to the invention shown schematically, which shows how several such devices are arranged offset from one another ■ can, for. B. for the aftertreatment of a rayon thread, this thread on or between each device and those in the aftertreatment coming liquids, vapors etc. is treated. The scheme only shows, of course a single unit. In reality, of course, there are many such in one machine Aggregates available.

In the diagram shown, the thread coming from a spinneret Sp first runs over the device Ents, whereby the thread turns are sprinkled with deacidification liquid or the device itself runs in a deacidification bath.

After the deacidification, the thread runs to and around a further device Wa according to the example shown, the thread being washed.

After washing out, the thread is now fed to the device Tr , where it is dried by hot air or in a drying room as it circulates around it. The thread can then be wound onto a bobbin Asp. The device and the arrangement of such device according to the invention can also be used for other purposes, e.g. B! for winding and forwarding fiber ribbons, strip-like structures, ribbon-like structures made of knitted or woven goods, whereby these can be drawn out or smoothed and then wound up with simultaneous processing for their particular purpose.
