METHOD OF STARTING THE SPINNING IN BOX SPINNING MACHINES Filed May 11, 1931 iwwm vm Y (ML mum I Patented x r. 19, 1932 UNITED STATES PATENT OFFICE LADISLAUS VON TOTHFAL'USSY, OI BERLIN-CHARLOTTENBURG, AN D RICHARD NAAOKE,
OI ZILLEBTHAL, GERMANY, ASSIGNORS TO SIEMENS-SCHUCKERTWERKE AKTIEN- GFSELLSCHAFT, OF BERLIN-SIEMENSSTADT, GERMANY, A CORPORATION GE GE MANY METHOD of STARTING TEE SPINNING IN BOX SPINNING MACHINES Application filed May 11, 1931, Serial No. 538,418, and in Germany May 7, 1980.
Our invention relates to box spinning machines, and more particularly to a method for starting the spinning of the threads) in box spinning machines or centrifugals provided with drawing mechanisms.
In box spinning machines or centrifugals provided with drawing mechanisms, i. e. in such machines which spin staple fibres, certain difficulties arise when commencing the spinning. Ifthe free end of thefroving is supplied to the quickly rotating box from the delivery rollers, as customary in the artificial silk or rayon industry, the thread usually breaks at once. The reason is thatat the moment when the thread is first subiected to a tensionedstrain by the centrifugal force of the rotating spinning box the thread is still without twist and thus unable to withstand the sudden strain. This is particularly liable to happen when the boxes rotate at high speeds.
It has already been proposed for starting the spinning of artificial silk on ring spindles to use a piece of auxiliary thread, one end of which is connected to the spinner, and the other end of which is connected by hand with the roving delivered to the spinner, for instance by twisting the auxiliary thread around the roving. This method may be also used for box spinning machines, but in that case the difficulty arises that the guide thread after it has been introduced into the spinning box, and if held at the other end by the operators hand in order to join it with the roving, becomes twisted too much, especially at high box speeds so that it usually breaks through this over-twisting before it' can be secured to the roving. To make such connections successfully requires an extremely high skill which it is not readi- 1y acquired, and which thus makes'the'spinning dependent on high grade manual skill of the operators.
These disadvantages are avoided according to the present invention by using an auxiliary thread which is coiled on a storage bobbin and which, after it has been introduced into the spinning box in the customary manner,
is quickly thrown over the delivery roller of the drawing device so that it immediately commences to run over this delivery roller into the spinning box. It thus receives in addition to its own twist only the twist which is normally to be imparted to the roving. As
soon as the guide thread has thus been elevation of a drawing and box spinning de-' vice embodying my invention, and
Fig. 2 represents a front elevation of the delivery rollers of the drawing device, and of the storage rollerv for the guide thread. Referring to Fig. 1, 1 and 2 are pairs of rollers of the drawing mechanism, 3 is the thread guiding funnel, 4 the spinning box or centrifugal, and 5 the roller or reel, carrying the auxiliary thread. According to our invention spinning is started by unwinding the auxiliary thread 6 from the storage reel 5 and passing it through the thread guide 3 into the spinning box, for instance by the known method in which an auxiliary liquid is employed. The auxiliary thread is then placed between the delivery rollers 2 of the drawing mechanism as indicated by the arrow 7. The delivery rollers 2 then continue to feed the auxiliary thread into the box. The roving is then passed through the drawing mechanism, joins and unites between and at the back ofthe delivery rollers with the auxiliary thread, and has in this way imparted to it a twist immediately on issuing from the drawing mechanism, so that itattains here already the requisite strength. As soon as this has happened the auxiliary thread may be cut off before it runs on to the delivery rollers.
Holding devices for the storage rollers or reels may be provided on the frame of the spinning machine. but the reel may also be portable and be attached easily rotatable to a belt carried by the attendant.
5 In order that the auxiliary thread may run correctly over the upper delivery roller, a thread guiding eye 8 or the like may be provided in front of this roller..
Fig-. 2, showing a front elevation of the delivery rollers of the drawing mechanism, illustrates the arrangement of the thread guiding eye 8 on the arm 9 which carries the axle or shaft for the upper pair of delivery rollers for two spinning stations.-
In order that the auxiliary thread may easily be passed around the end ofpressure rollers, which latter are mounted on the free ends of their respective axles or shafts, a rounded cap or dome may be provided at the outer face of these rollers. In Fig. 2 these lateral end caps are marked by the reference numeral 10. In a preferred embodiment of our invention the pressure rollers are journalled on the free ends of stationary axles or studs so that the caps 10 are provided on the stud ends and are likewise stationary. Tests with the new method and apparatus have proved that it is possible to start the spinning satisfactorily even with the finest theads at the highest delivery sneeds and at-the maximum speed of the box. In order that the auxiliary thread may easily be distinguished when subsequently unwinding the cheese, the auxiliary thread may accord- I ing to our invention be given a special color. If the cheese is unwound from the outside towards the inside, the end may thus be found at once. The auxiliary thread may then be removed entirely. 40 We claim as our invention:
Method of starting the spinning of threads in box spinning machines, consisting in introducing into the spinning box an auxiliary guide thread, then placing said thread betweenthe delivery rollers of the drawing device for the roving, and then passing the roving through the drawing device. whereby the roving is automatically entwisted with the guide thread before the roving is drawn into the box.
- In testimony whereof we 'afiix our signatures.
