Combined machines are now being used in the artificial silk manufacture which .twist the threads andat the same time wind them on cylindrical or conical take-up spools. These spools are usually driven either by cylindrical padded rollers or single padded conical rollers which have secured thereon paper tubes. With either driving means, the thread lying on the take-up spools contacts therewith and the resulting friction and pressure may cause considerable damage to the delicate threads.

Moreover, by driving the conical take-up rollers or spools by cylindrical rollers, certain parts of the tube are apt to slip, depending upon the amount of yarn that has been taken up on the larger or smaller diameter of the conical spool. This slippage will damage the yarn and owing to the varying take-up will cause an uneven twist.

The slipping can be eliminated by using as the driving means a conical member or cylinder provided that the winding is so arranged that the points of the conical drives and the points of the cones coincide at every winding thickness.

Such winding may be obtained by diminishing or increasing the oscillation of the thread guiding means. Since the winding thickness of the cones is not the same on the length of yarn but increases towards the thicker end of the conical spool, the inclination of the outer layer of the threads will increase constantly. Owing to this inclination the layers will tend to slip off, which slippage interferes considerably with the after-treatment of the yarn.

Accordingly, it is an object of this invention to Figure 1 is a diagrammatic view of the driving arrangement; and Fig. 2 is also a diagrammatic view but showing the relationshipv between the twisting spindle and the take-up means.

Referring now to the drawing there is shown a twisting spindle 1 driven by any suitable means such as a belt 2. From the spool 3, upon which the thread or yarn is wound preparatory to twisting. the'thread or yarn 5, is passed through a (Cl. 117-26) I suitably secured to the member 7, and then passes to a thread guide 8 secured to an oscillatory member 9.

To avoid the destruction of the yarn body by 50 the thread guide lying on the yarn, a lever 10 is pivotally secured to a support 11, an end of which 12 lies below the thread guide 8 and the other end 13 between the thread brake on the running thread. Should the thread at any time break, that end of the lever 13 resting on the moving thread falls down and the other end striking the thread guide 8 raises it so that it will not contact with the yarn body.

The tube 14 of any suitable material such as card-board is mounted on spindle 15 which is suitably secured to an arm 16 pivotally secured at 1'?- to a support 18. A friction disk 19 is secured to the spindle in any suitable manner at a positioned a disk 22 which, contacting with the cone and disk 19 transmits rotation from the shaft 21 to the spindle 15. This disk is rotatably mounted on an arm 23 pivotally'secured at 24 on the support 18 immediately below the pivotal 35 connection of the arm 16.

Since the thickness of the thread increases, the rotation of the spindle must be decreased in order to maintain constant the peripheral speed of the thread body. Means. are therefore pro- 9 vided to gradually shift the cone from right to left on the shaft 21 and the mantle line of the cone must be curved to obtain the desired result. The cone 20 is shifted from right to left by means of a forked member 25 splined to a fixed shaft 26. The forked member is shifted by means of a spring-pressed threaded half-nut 27 which is pivotally secured thereto and which contacts with a lead screw 28 secured to a shaft 29. This shaft is rotated by shaft 21 through suitable gearing 31.

The operation of the device is as follows:

' A spun spool of thread is placed on the twisting spindle and the thread is passed through a guide, over a thread brake and is placed on the spool 14 by means of an oscillating guide. The spool is rotated thru disks l9 and 22 by means of the cone 20. To maintain the peripheral speed of the thread body constant, the cone is gradually shifted from right to left'by means of the 110 lead screw, and the disks 19 and-22 remain in contact with each other, and the disk 22 in contact .with the coneby virtue of the pivotal mounting of the arms 16 and 23 to which they are respectively connected. When the half nut has traversed the length of the lead screw, it is pressed against the shaft 29 and by virtue of a suitable stop means 30 the disk 22 is moved away from the cone thereby stopping the winding mechanism. 7
