Abstract: <PICT:0429485/IV/1> <PICT:0429485/IV/2> <PICT:0429485/IV/3> In spinning and after-treating artificial silk, the silk is wound on circumferentially driven hoop-shaped winding carriers 34 mounted at the side of the spinning machine 1 adjacent the spinning bath 2, on a member which may be rotated when the winding is completed to move the wound hoops into a position for delivery to an after-treatment tub 4, and to bring a fresh set of hoops into the winding position. Mounting-supports 5, Fig. 3, on the frame of the machine support a shaft 6 on which are arranged bearing members 7, 8 one of which, 7, provides a mounting disc 9 for the shaft 6, and each of which has oppositely disposed arms 10, 11 connected by shafts 12, 13 carrying rollers 14, 15.  The bearer members 7, 8 are connected by shafts 18, 19 and 20, 21, the latter pair extending through adjacent spinning units along a common shaft 6.  The bearer member 7 houses two chain drives 23, 24 connecting shafts 18, 20 and 19, 21.  The shafts 20, 21 project through a gear wheel 25 on the shaft 6 and carry driving pinions 26, 27.  A number of winding carriers 34 are supported and circumferentially driven in the position I, Fig. 1, by rollers 33 on the shafts 19, 21 which are driven from the drive shaft 30 by gears 31, 27 and the chain drive 24, and silk 36 issuing from a row of nozzles 35 is wound on these carriers.  On completion of the winding the entire structure is turned through 180 DEG  by the main shaft 28 and gears 29, 25, so that the wound carriers move to the position III, Fig. 1, and a fresh set of carriers supported on rollers 32 on shafts 18, 20 are brought to the winding position, the rollers 32 being actuated by gears 31, 26 and chain drive 23. The supporting structures are enclosed by a casing 38, Fig. 1, with a closure lid 39.  The lid 39 may be opened by means of a crank drive 42, 43 so that the wound hoops pass into the after-treatment tub 4 and a fresh lot of hoops may be placed in position ready for subsequent movement into the winding position. In a modification the lid is hinged at the top end and a small subsidiary lid opening downwards is arranged below it.  The lower part 41 of the casing joins with one wall of the spinning bath 2, and the casing has a window panel 44 and a flue 45. The tub 4 communicates by flues 46 with the flue 45.  In place of the casing 38 the hoops 34 may be held to the supporting structure during rotation by prolongation of the arms 10, 11.  A further after-treatment tub may be arranged beneath the first tub, the upper one being pivotally mounted on trunnions so that the hoops may be tipped from one tub to the other, or two tubs may be arranged side by side, the hoops either passing directly into the first tub or rolling on the lid of this tub into the second tub. To ensure shock-free movement of the supporting members, a disc 50, Fig. 4, with recesses 51 is mounted on the shaft 6, one of the recesses co-operating with a pawl 52 arranged laterally on a chain wheel 53 rotatably mounted on the disc 50.  A chain 54 passes round the wheel 53 and is connected at one end to a crank 55 and at the other to a counterweight 56. Rotation of crank 55 by means of shaft 70 actuates chain wheel 53 to rotate disc 50 and house the shaft 6.  When crank 55 reaches B, the rotational movement is stopped and chain wheel 53 turns idly back, pawl 52 sliding on disc 50 to co-operate with the other recess. After each displacement a spring pressed locking lever 57 co-operates with one of two notches 58 in the raised rim of disc 50.
