The invention relates to methods of and machines for spinning and aftertreating artificial silk.

In the method of spinning and aftertreating artificial silk according to this invention freshly spun artificial silk is wound on winding carriers of a form similar to a hoop or felly after the carriers have been moved, by means of a common rotatable supporting structure, into a position for actuating and winding the same which is situated on the side of the artificial silk spinning machine adjacent to the spinning bath vat and in which the carriers are supported and actuated at their circumference and from which position the winding carriers on being wound with artificial silk are moved, by turning the supporting structure, to a position of delivery situated on the rear side of the spinning machine from where the carriers are passed into aftertreatment means, the supporting structure moving during this turning movement a fresh set of empty hoop-shaped winding carriers having been previously inserted therein into the position for actuating and winding the same.

This method offers the considerable advantage that the artificial silk need not be touched with the hands from the moment of generation to the very end of the aftertreatments to which it is subjected, as during all the operations carried out in connection with the aftertreatments the material is permanently accommodated in one and the same machine.

In the accompanyingdrawings the method according to the invention is illustratively exemplifled, in which a constructional form of the ma- 'chine for carrying the method into eifect is shown by way of example only, this machine also forming part of the invention. In the drawings- Fig. 1 shows a sectional elevation of the machine;

Fig. 2 is an end view of the rotatable supporting structure showing the drive of the latter to be arranged at this end;

Fig. 3 shows a fragmentary side elevation partly in an axial section along the line AB in Fig. 1;

Fig. 4 shows an elevation of a modification of the rotatable supporting structure;

Fig. 5 shows an axial section of the drive, and

Figs. 6 and '7 each represent a sectional elevatlon of two different modifications of a detail, viz. the arrangement of two aftertreatment vessels instead of one only.

Referring particularly to the Figs. 1 and 2 of the drawings, the numeral I refers to the frame of the machine at one side of which the spinning bath vat 2 and the water gutter 3 are arranged, whereas at the other side of the machine frame a tub 4 containing an aftertreatment liquid such as wash water or a desulphurizing solution is positioned. 'On the upperside of the machine frame 5 l mounting supports 5 are secured in which a hollow shaft 6 has its bearings. Between each two adjacent mounting supports 5, on the hollow shaft 6 two bearer members i and S for one and thesame supporting structure are arranged (Fig. 10 3), one of which being in the form of a hollow body providing at the same time a mounting disk 9 for the hollow shaft 6 in the adjacent support 5. The other bearer member 8 is rigidly secured to the central shaft 6 at the side of the other mount- 15 ing support 5.

The bearer members i, 8 are each provided with two diametrically oppositely disposed arms ii! and H (Fig. 1) each for receiving the respective end of two shafts l2 and 53 on which rollers l4 and 20' 15 respectively are mounted. The individual bearer members i, 8 resemble a spider with the arms I0 and i l extending in the cross direction to the other arms. In addition to being interconnected by the shafts I2 and I3 at the shorter arms, the two bearer members i and 8 of one and the same supporting structure are joined at their longer arms by two shafts H3 and i9 (Figs. 1 and 3) and besides by two further shafts 20 and 2!, the latter shafts extending through one of the adjacent supporting structures or else even through several such structures as arranged on the same common hollow shaft 6.

In the mounting support 5 shown to the left in Fig. 3 the two through- shafts 20 and 2| are passed through the mounting disk 9 of the bearer member I of the next following supporting structure. The individual hollow bearer member l accommodates two chain drives 23 and 26 for operatively interconnecting on the one hand the shafts l8 and 2t and on the other hand the shafts l9 and 28. This construction has the advantage of providing an adequate and safe supporting, i. e. bearing engagement for the through-shafts as many times in the length of the machine as required.

The two shafts 20 and 2!, which are positioned nearest to the central shaft 6, are provided on their ends shown to the right in Fig. 3 which project out of a gear wheel 25 secured on the hollow shaft 6 (see also Fig. 2) with driving pinions 26 and 21 respectively. A gear wheel 29 secured to a shaft 28 (Fig. 3) cooperates with the gear wheel 25 for common actuation of the supporting structures carried by the central shaft 6. On a shaft 30 (Fig. 3) a gear wheel 3! is fixed which meshes with the pinion 721 on the shaft 2 l, as shown, for rotating the shaft 2 l. By periodically turning the supporting structure, i. e. the row of such structures, through angles of 180 the pinions 26 and 21 are alternately moved into engagement with the stationary driving wheel 3i, so that each time one of the shafts 2t and 2! and together with it that one of the two shafts l8 and H? which is coupled to the respective shaft 20 or 2| are actu ated by means of the correlated chain drive 23 or 24.

Consequent thereon, rollers 32 and 33 respectively are turned depending on which pair of operatively interconnected shafts 20, I8 or 2|, H! are actuated, the rollers 32 and 33 serving for supporting and driving Winding carriers 34 of a form similar to a hoop or felly, as will be seen in the Figs. 1 to 3. It will be readily'understood, that a comparatively large number of winding carriers 34 can be arranged side by side in the length of the individual supporting structure, the winding carriers being merely supported at their raised circumferential edges.

In the position of the supporting structure shown in Fig. l the winding carrier supported by the rollers 33 of the pair of shafts 2! and I9 occupies a position designated by I for actuating and winding the carrier. To this end, the shaft 2! is coupled to the drive shaft 33 by interengagement of the wheels 2i and 3! (Fig. 3), the winding carrier thus being circumferentially actuated by the rollers 33 turning together with the respective shafts 2! and I9. In this manner the artificial silk thread 36 emanating from the nozzle 35 is wound on the winding carrier 34 turning in the direction of the respective arrow shown in Fig. l by means of a guide 3?.

On this winding carrier 3 3, that is, the entity of winding carriers occupying the driving and winding position I respectively being wound with artificial silk, the supporting structure, i. e. the entire row of supporting structures as provided are turned through an angle of 180 by the main shaft 28 (Fig. 3) in the direction of the arrow designated by II. By this rotational displacement the wound winding carriers 34 are moved from said position I into the position of delivery as indicated by III in Fig. 1 from whence they are passed on towards the aftertreatment tub 4, as will be hereinafter more explicitly explained.

On the termination of the said rotational displacement of the supporting structure, a fresh set of empty winding carriers, which had been previously placed on the supporting structure at the delivery position III occupies the driving and Winding position I. This fresh set of winding carriers then rests on the rollers 32 of the two shafts I8 and 2B which on the termination of said rotational displacement of the supporting structure are moved into operative engagement with the drive shaft 36, the two longer arms of the bearer members I, 8 and the two shorter arms thereof having mutually changed their positions. At the same time the shafts l9 and M are disengaged from the drive shaft 30 during the said rotational displacement of the supporting structure, so that the driving movement of the winding carriers supplied with material is stopped and the still oncoming artificial silk is passed over to the winding carriers having been moved into driving and.

winding position due to the rotational displacement of the supporting structure, these carriers being thus wound with material.

The supporting structures present in the machine are inclosed by a casing 38 (Fig. l) partly of arcuate cross section and provided with a closure lid 39 situated in the vicinity of the position III for delivering the filled and inserting empty winding carriers.

In the constructional example of the machine shown in the drawings the casing serves for securing the fellies against dropping off the supporting structure. It is, however, possible to construct the supporting structures without departing from the spirit of the invention, in such manner, that the fellies stick to the supporting structure by themselves, without the aid of the casing, until they arrive at the lowermost position at the rear for dropping off by being released from the supporting structure. For this purpose it is only necessary to prolong the arms l0 and II and to render these arms slightly yieldable, in order to provide for the carriers to be retained in position during the rotational displacement without cooperating with the casing but to be free to drop oiI in the respective position at the rear.

As the follies are brought to the position for leaving the supporting structure, the casing must be opened to leave the way free for them to be removed. To this end the closure lid 39 is connected to the lower part 41 of the casing through the intermediary of a shaft #8 so as to be adapted to be rocked into open position by means of a crank drive 42, 43. The casing joins with its lower part 4! with one of the longitudinal walls of the spinning bath vat 2 and is provided above the other longitudinal wall of this vat 2 with a window panel 44 and at the ceiling with a flue 55 for educting the gases which accumulate in the spinning and winding space inclosed by the casing as Well as in the ,aftertreatment tub 4 in the di rection of the respective arrow. The flue communicates with the said uncased space by conduits 46 arranged on a common level.

During the rotational displacement of the supporting structure the wound winding carriers 34 being moved out of the actuating and winding position I are held in position on the supporting rollers and the rollers M or I 5 respectively by the arcuate portion of the casing, whereby the windingv carriers are prevented from rolling out of the supporting structure as they are swung over to the delivery position. On opening the lid 39 by means of the crank drive 62, 43 the wound fe-llies occupying the position of delivery III disengage from the supporting structures by gravitatively rolling on the open lid 39 which had been previously rocked to enter the tub 4 with the cover 5'! of the latter being removed. In this way the winding carriers are permitted to roll or slide into the tub 4 inside of which they come to stand on hearing strips 48.

In Fig. 1 two intermediary positions of the winding carriers on their way from the position of delivery III to the tub 4 containing the aftertreatment liquid for the artificial silk are indicated by chain dotted lines. After in this fashion a set of fellies wound with materials has been removed from the supporting structures into the tub 1, a fresh set of empty hoop-shaped winding carriers is put in their places on the supportingstructure. This is accomplished by at first placing the fellies on the lid 39 having been rocked back into a convenient position and then closing the lid, thereby the fellies are inserted into the supporting structure, that is, between two arms of the spider, as will be readily understood.

During the next following rotational displacement of the supporting structure, which takes place after a period of time necessary for winding a set of'winding carriers, the winding carriers which had been previously inserted in empty condition are carried along by the supporting structure in such a manner, that the carriers roll on the lower arcuate portion of the casing until they are raised to a level permitting the carriers to rest against the rollers 32 or 33 on the shafts I8 and 28 or 9 and 2| respectively, in which condition of supporting the winding carriers arrive at the driving and winding position.

It is of eminent importance that the rotatable supporting structures inclusive of the fellies, which parts together are of a considerable weight and the former being eccentrically loaded, are moved out of position free of shocks and entered into position of rest free of shocks again. Furthermore it is essential that the supporting structures are every time adjusted to and retained in the same respective positions of rest accurately.

In the Figs, 4 and 5 a device well adapted for thispurpose is shown. On the central hollow shaft 6 a disk is fastened the circumference of which is provided with two oppositely disposed recesses 55. One of these recesses cooperates with an actuating pawl, 52 which is arranged laterally on a chain wheel 53 rotatably mounted on the disk 50. Alternatively, two actuating pawls 52 may be connected with the chain wheel 53, one each for cooperation with either of i the two recesses 59 of the disk 59. Round the chain wheel 53 a chain 54 is passed the one end of which is attached to a crank while from the other end a counterweight 56 is suspended. The parts 50 to 54 form oonjointly a locking device operating in one direction of driving only.

During turning the crank 55 in the direction indicated by the arrow in Fig. 4 the chain wheel 53 is actuated by the chain 54, thus rotating the disk 59 and consequently also the central shaft 5 in unison therewith by means of the actuating pawl 52. In this manner the bearer members of the supporting structures and thus the structures themselves are also actuated, the former being, as aforementioned, firmly connected to the shaft 6. i

In Fig, 5 only one bearer member I is shown which is, however, devoid of hollow arms as the chain drives 23 and 24 between the pairs of shafts i8, 20 and l9, 2! respectively are here arranged at the side of the bearer member I.

The rotation of the chain wheel 53 and thus that of the supporting structures is positively effected at least during half a revolution of the crank 55 from A to B, whereupon the driving motor is stopped or a coupling is disconnected respectively which serves for connecting the motor with the shaft IE1. Consequently, the chain wheel 53 is idly turned back by action of the counterweight 56 into its initial position A. This position represents at the same time the starting position for the next following positive operation of the shaft Iii.

During this operation the pawl 52 slides on the disk 50 in order to enter into engagement with the opposite recess 5| after each displacement of the supporting structure by an angle of 180 a spring-pressed locking lever 51 cooperates with one or the other of two notches 58 in the disk 50 by which means the supporting structure is secured in the respective position of rest. Both of the diametrically opposed notches 58 are situated in a raised rim on the disk 50.

The described driving arrangement serves the purpose to impart to the supporting structures of a large size a gradually accelerated starting movement and a gradually decelerated stopping movement during the rotational displacements of the same in order to provide for the structures to depart from and to arrive at the respective positions of rest free of shocks. In carrying out these displacements it is important that the shaft Hi carrying the crank 55 moves at certain intervals in a positive manner through at least half a revolution and is adapted to pass the dead center position B and that, by action of a counterweight, such as a spring or the like, the crank 55 is returned into the initial position A in a dependable manner.

In the modified arrangement of the aftertreatment means shown in Fig. 6, in addition to the tub 4 a further tub 4 is provided for cases where the aftertreatment of the artificial silk wound on the winding carriers is effected in two successive working phases in two separate tubs. The first working phase takes place in the upper tub- 4 into which the'fellies 34 wound with the artificial silk are fed from the delivery position III by opening the lid 39 provided on the casing 38 and a further pivotal lid 58. In this construction the lid 39 is rocked upwards by means of the crank drive 42, 43, as evident from the drawings, whereas the lid 60, which is mounted on a shaft 6! and connected with a crank drive 63, 64 by means of a tension member, is rocked downwards by means of the latter crank drive. The tub 4 is tiltably arranged by means of trunnions 59.

After the artificial silk has been subjected to an aftertreatment in the tub 4 while still in position on the winding carriers, which had been con- 'veyed into this tub from the position of delivery III, the tub 4 is rocked into the chain dotted position thus permitting the winding carriers to roll out of the tub 4 and to drop into the tub 4' which had previously been uncovered and in which the artificial silk is to be subjected to a second aftertreatment on the winding carriers. On the winding barriers being removed from the position of delivery III into the tub 4, a fresh set of empty winding carriers can be inserted in the supporting structures at the said position.

In Fig. 7 a further modification of the aftertreating arrangement is shown wherein the second tub 4' is positioned at the side of the tub 4 approximately at the level of the latter. This arrangement provides for completely aftertr-eating the artificial silk as supplied to the individual tubs in position on the winding carriers 34 in the respective tub. In this arrangement the wound winding carriers 34 can be passed from the position of delivery III into the tub 4, the cover 41 of which had been previously removed by opening the lids 39-and provided on the casing 38 or by passing the winding carriers across the cover 41 of the tub 4 on opening the lid 60 into the tub 4' after the cover 49 of the same had been removed. The possibility of passing the wound winding carriers selectively from the position of delivery III into one or the other of the two tubs is of particular importance in all cases where the aftertreatment of the artificial silk requires more time than the spinning and winding operations.

Naturally more than two tubs may be provided for the aftertreatment.
