H., OF BERLIN -IJICHTEN BERG, GERMANY, A CORPORATION OF GERMANY TWISTING CONTINUOUSLY SPUN ARTIFICIAL THREADS Agplication tiled March 6, 1930, Serial No.
Mypresent invention relates to an improvement in twisting artificial silk threads. In most of the hitherto known twisting systems, especially in the case of operating 5 with artificial silk threads, twisting is start; ed with a yarn already wound up on a reel or a bobbin. The end of the thread or of the bundle of threads to be twisted is, for instance, fixed on the winding spool by passing it several times around the latter, while the apparatus is at rest; then the thread is subsequently guided through the ditferentrunning otl' mechanism (draught rollers, thread-guides, eyelets, travellers, etc); tinally, the twisting spindle, "the winding-on and running off mechanism are put into operation.
'hen spinning and twisting artificial threads simultaneously, the application of .20 these methods will, however, not be possible, since the spinning operation does not permit any discontinuity or interruption. Since the winding-on devices of all of the known mechanisms can take up only a limited length of threadit'is necessary that a device, when full, may be replaced by a fresh device so that twisting may proceed without disturbance of the spinning process. This can be done in known manner with a spinner-ct operating with low speeds of draught (-10 to 60 meters per minute) as generally used in wet centrifugal spinning processes by rinsing the end of the thread bymeans of a liquid through the funnel-like thread-guide into the spinning pot. In view of the very high speeds of draught (150,to 200 meters per minute) in dry-spinning processes, however, and in View of the extremely small weig'ht per unit length ofthread spun by 40 the dry-spinning method complicated devices are in most cases necessary for the same purpose; for instance, in box spinning according to a dry spinning process it is necessary to use a current of compressed air.
According to my invention, it becomes possible to start easily with the usual twisting systems the twisting of a thread delivered at a high speed or to interchange the collecting devices after having taken up the desired quantity of twisted yarn without loss of 483,695, and in Germany March 28, 1929.
fibers. For this purpose, use is inade of an auxiliary thread of sutficient strength and length, and of a fineness corresponding with the tit-re of the threads to be twisted in each case. This auxiliary thread is doubled, and its ends are introduced into the twisting machine while the loop of the thread, is held firml with the fingers of one hand. The twisting machine is set into operation whereby the doubled thread immediately becomes twisted. Meanwhile, the artificial thread issued by the spinning device and wound on a lap roller or running to a collecting device, drawn into a loop which is then passed through the loop of the auxiliary thread. The loop of the auxiliary thread is then released by which manipulation the main thread is attached-t0 it and shortly afterwardsis drawn into the winding device. At the same time the length of the artificial thread between the auxiliary thread and the lap spool or the collecting device is broken. Theartificial thread is held securely by the closed loop of the auxiliary thread, and is guided by the-latter onto the winding-on-device. This terminates the operation which allows to start the twisting of the thread issued from thespin-neret or to guide the thread from a collecting device already full to a new one without interruption of the spinning process.
In the annexed drawings there are illustrated by way of example some modes of executingmy invention with various twisting systems;
Figs. 1 and 2 illustrate the application 0 my invention in box twisting, Fig. 3 in ring twisting and Fig. 4 in fiyer twisting of artificial threads. Figs. 5 and 6 show the same principle applied in interchanging the collecting devices in a ring twisting machine; however, itmay be used in an analogous manner in other twisting machines.
Referring to Fig. 1, a designates the thread issued from the spinning nozzle. It passes around a roller 0 and is at first wound on the lap roller 6. In order to introduce the thread into the centrifugal twisting machine, the ends of the doubled auxiliary thread d are introduced through the funnel h into the centrifu e 9 against the wall of which they are held y centrifugal force of the running machine. At the same time, the doubled thread d, the loop 6 of which is held with the fingers of one hand, is twisted. Now, through this loop e is passed (see Fig. 2) a loop 7 drawn carefully from the main thread a and at the beginning also held with a finger at f. The loop 6 is then released, whereupon it closes and holds the loop f of the main thread; the loop f is also released, and the main thread is detached from the lap roller 6, and is drawn by the auxiliary thread d into the box 9. The twisting of the artificial thread is thus commenced.
Fig. 3 shows the application ofthe same process in ring twisting. The doubled auxiliary thread d is secured to the winding-on spool i, and passed through the traveller m and the thread guide n. The loop e is held with two fingers and the spindle is is set in motion, whereby the doubled thread is twist-Iv ed. A loop of the main thread a is drawn at f and passed through the loop a of the auxiliary thread, the further procedure being the same as that described above.
Fig. 4 illustrates the application of. the same process in flyer twisting In this case also the doubled auxiliary thread d is first secured to the winding-on device 1', there-upon passed through the eyelets of the fiyer g and held at its loop 6. The flyer spindle p is set in motion and the loop f of the main thread is passed through the loop 6, the further operations being the same as those already described.
In Figs. 5 and 6 i designates a full spoolv and 2' the empty spool to which is to be transferred the thread a issuing from the spinning apparatus. In the ring twisting apparatus, illustrated by way of example, several spindles is are arranged in a row, the thread is 7 caused to reciprocate vertically in known a ring l.
manner during the twisting operation by means of the ring rail 8, and wound on by means of the traveller m which moves in the thread I guide, around which, during the twisting operation, the balloon of the yarn is formed.
When the spool 11, is full, the doubled auxiliary thread d is wound on the adjacent empty spool i passed through the traveller m and the eyelet n. The loop u of the auxilia'ry thread cl is held between two fingers of the right hand; the spindle is is then set in rotation whereby the double thread d is twisted. At the same time, with the third finger of the right hand, the loop *0 is drawn out from the main thread a and passed through the loop u, the main thread is cut by scissors t and the loop u is released which immediately closes. The free end of the main thread a is securely held by the auxiliary thread andguided on the empty spool.
c is the draught roller and n the In this way the thread is transferred from the full spool to the adjacent empty spool without interruption of the spinningprocess. In the case of spinning at several places at the same time, there bein a spinning'pla'ce, between each pair of a acent twisting devices, the threads can be transferred in the same manner from a collecting device either to the device on its right or to that on its left, pro vided that the number of twisting devices exceeds by one the number of the corresponding spinning places. Instead of a ring twisting device any other of the known twisting devices may be used.
What I claim-is In a process of twisting a continuously spun artificial thread the steps which comprise doubling an auxiliary thread to form a loop, introducing the both ends of'the auxiliary thread into the twisting device, pulling out a loop from the main thread-to be twisted,
setting the twisting device'in operation to twist the "auxiliary thread, and passing the loop of the main thread through the loop of the auxiliary thread. Y
In testimony whereof, I aflix my signature.
