In the known construction of reels for continuously winding threads the thread is wound while it is being laterally advanced, so that it formsa helix on the reel. On the reel, the threads, ribbons, or the like are treated with chemical agents and, if required, dried. The treatment or the different stages thereof require 'a minimum length of thread on the reel and a minimum period of treatment. For a given speed of draught and given dimensions of the reel, these minima depend on the lateral advance of the threads per revolution of the reel, in other words, on the pitch of the helix formed by the thread. The known reels of this kind do not permit control of the. pitch of the helix of thread, when the speed of draught and the dimensions of 'the reel have once been fixed, so that the length of thread on the reel and the period of after-treatment cannot be varied. This lack of flexibility becomes particularly troublesome if the reel is to receive threads and ribbons of different titers in succession, as is frequently necessary in spinning artificial silk or ribbons by the dry or wet spinning. process.

According to this invention, reels for continuously winding threads or the like, of the kind wherein the yarn is wound temporarily on the reel and is automatically laterally advanced, are so constructed that the lateral advance of the thread per revolution, 1. e., the speed with which the thread is guided across the reel, can be controlled so that the advance can be selected to suit the breadth of the yarn or to produce during the different stages of treatment a. winding in the form of a helix of a fine or coarse pitch.

In a preferred construction, the pitch of the helix can be varied while the reel is in operation so, for instance, at the beginning of the-spinning process, more particularly when spinning several threads one beside the other.

The controlling device depends on the form of reel used. The reels contemplated by this inven tion are primarily designed for receiving artificial silk, ribbons, or the like, which are to be subjected to an after treatment. They may be used, however, for the continuous treatment of any threads, yarn, ribbons or strips of films which are caused to pass the reel in a single layer only.

In order to more fully explain our invention, we shall describe, by way of example, several devices for controlling the advance of the thread, suitable for various kinds of reels for continuously winding threads. The devices fall under two heads:

(a) The threads are laterally advanced by means of rotating carriers of drum form which need not have continuous surfaces but may consist of groups of bars. The axles or guiding or driving disks of these carriers are inclined to- 60 wards each other and are also mounted in slight eccentricity. The advance of the device depends upon the amount of the inclination and the eccentricity of the axles or guiding or driving disks.

Therefore, according to this invention the advance of such reels is made controllable by providing the possibility of varying the eccentricity and/or the inclination of the axles or guiding or driving'disks of the carriers, it being understood that a slight eccentricity and a slight inclination is the necessary condition that an advance takes place. Figs. 1 to 16 relate to this kind of reel.

(b) The threads are advanced by means of devices which are coupled with the reel in such a manner that the desired advance of the thread is produced in the course of a given number of revolutions of the reel.

In this kind of reel, the advance of the yarn is controlled by means of a variable gear between the axle of the reel and a device by which the thread is laterally displaced.

This kind of reel is described in German Patent Specification Nos. 236,584, of February 20, 1910, to Vereinigte Glanzstofiabriken, and 415,479, of October 25, 1923, to C. R. Linkmeyer.

In the accompanying drawings, Fig. 1 shows a reel according to this invention in which the device for varying the advance can only be regulated when the reel is out of operation. The reel comprises two series of bars II and II mounted one within the other. The bars I I are connected by flexible joints 40 with the spokes 6 of driving disks which are fixedly mounted on a shaft I by means of a device which permits the regulation of the advance and which is shown in detail in Fig. 2. The shaft I rotates in bearings on standards 20 and is driven by a belt pulley 29. The bars II are fixed on hollow axles I which surround the shaft I and are rotatably mounted on the standard 20, and driven by the bars II'. The motion of the hollow axles I is transmitted by gears 31, gears 38 and shaft 39 from one to the other.

Fig. 2 shows in section the device which permits the regulation of the advance of the reel by changing the eccentricity or the inclination between the driving disks or end members of the reel sections that include the respective groups of bars II and II'.

The axle I is housed in a-bearlng bush 2 of inside dimensions necessary to give the axle the desired play. The ball bearing 3 is fixed on the bush 2 by the threaded ring 4. The casing 5, carrying the spokes 6, encloses the ball bearing 3 which is covered by the lid 1 and further tightened by two felt washers 8 in order to protect the ball bearing 'from being soiled by treating liquids. The screws 9, symmetrically arranged on each side of the disk, serve for adjusting the inclination and the eccentricity of the disk, the spokes 6 of which carry the groups of bars constituting the drum; Thus when the disk is at rest, it may be given any inclination and eccentricity by changing the inclination of the bush 2 in relation to the axle I.

" Figs. 3 and 4 represent diagrammatically in elevation and in plan, respectively, a complete reel with a device for regulating the speed of advance of the thread, as described with reference to Figs. 5 and 6.

On the stationary sleeve Ia, there is eccentri- .cally mounted the drum II by means of ball bearings. The motion of driven gear wheel 26 is transmitted to the bevel gear drive 21 and, by

ary sleeve I a carries a second independent drum II' which, as shown, has an upwardly directed eccentricity. The bars of drum II are arranged between those of drum II and serve to drive that drum, whereby both drums rotate at the same peripheral speed. The guiding or driving disks of the drums are inclined to the axle so as to form equal but opposite angles, whereby the thread is wound on the reel in the form of a uniform helix.

Fig. 5 is a horizontal section through a device by which the speed of advance of the thread can be controlled while the reel is in operation, and Fig. 6 is a section of Fig. 5 on the line G6.

In the stationary sleeve Ia there is rotatably mounted a shaft I' having a threaded portion I2.

The sleeve is slotted parallel to its axis along diametrically opposite lines and in each slot slides a bearing piece I3 which may be ofstone and has inclined faces. These pieces are screw-threaded to engage the screw-threaded portion I2. By turning the hand wheel I4, the pieces 4 are removed axially. An eccentric bush 2 has projecting portions I5 which rest on the inclined surfaces of the pieces 4; when it is desired to alter the speed of advance of the thread by changing the inclination of the casing 5, the bearing pieces I3 are moved axially to cause the bush 2 to rock about the axis of the pins I6. The ball bearing 3 is held in place on the bush 2 by the screw ring 4. The ball bearing is enclosed by the casing 5, a lid 1 and the eccentric rings 4. As there must be some play between the casing 5 as well as the lid I and the eccentric rings 4, elastic felt washers 8 tighten the enclosure of the ball bearing. The degree of inclination. obtained is indicated by pointer I I, moving in front of the dial I8. The nut I9 serves to lock the device in the adjusted position. v

Another form of reel having inclined eccentrics for controlling the speed of advance of the threads is based on the. following principle:

The eccentric arrangement of the axes of the disks or end members of the two groups of reel bars produces relatively radial displacements of adjacent bars of the two groups as the reel is rotated, and the inclination of the axes of thedisks produces relatively axial displacements of the bars of the two groups. The maximum advance of the thread per revolution of the reel is determined by the angle of inclination of the axes, and this should be so selected as to permit the maximum required speed of advance of the thread. Although the extent of the relative axial displacements of the two groups of bars is fixed by the selection of the angle of inclination of the axes of the supporting disks for the groups of bars, the advance of the thread depends upon the correlation of the radial and axial displacements of the groups of bars. Angular adjustment of the eccentricity of the two supporting axes alters the relative timing of the radial and the axial displacements of the two groups of bars. When the eccentricity is such that one group of bars is projected radially to support the threads during a period when the supporting bars are displaced only inone direction, the advance of the thread is a maximum. Similarly, when the eccentricity is such that the thread-supporting group of bars moves in opposite directions and by equal displacements, the advance of the thread will be zero. A consideration of the relative radial and axial displacements will show that any desired advance rate between zero and the maximum can be obtained by a 90 angular adjustment of the eccentricity.,,

standards and driven by the belt pulley 29. v

The group of bars. II is mounted in fixed connection on the shaft I'.- The bars I I' are connected by flexible joints 40 to spokes 6 that include the device for changing the advance of the reel and are driven by the bars II.

Figures 9 to 12 illustrate a device operating on the aforesaid principle, Fig. 9 being an axial section, Fig. 10 a horizontal section on line Ill-III of Fig. 9, Fig. 11 a cross-section on line I I-I I of Fig. 9, and Fig. 12 a cross-section on line I2--I2 of Fig. 9.v

The standard 20 serves as a bearing for an eccentric bush 2, on which is mounted a bearing bush 2' obliquely bored for the maximum required speed of advance of the thread. This bush 2' is held in position by the threaded ring 2I. The ball bearing 3 is mounted on the bush 2 and is held in position by the threaded ring 4, the casing 5 and its cover I. By means of a lever 22' fixed on the bush 2', the latter can be turned through an angle of 90, as indicated by a pointer II moving over'a dial I8, the. lever being fixed in the desired position by a nut 23.

Figures 13 and 14 represent diagrammatically,

' in elevation and plan, respectively, another form of reel in accordance with the invention.

35 The axle I rotates in bearings on standards 20 and is driven by the belt pulley 29. The drum II is fixed to the axle and drum 3!] is driven by drum II. Drum 30 comprises two annular disks eccentrically mounted on the axle and carried by standards 35, which are capable of being rotated about a vertical axis by being mounted on turntables 3|. One of the turntables 3| has a pin 32 which, when moved by rotation by means of the hand wheels I4, gives the supporting disks of drum II' any desired inclination. The degree of adjustment of the speed of advance of thread is indicated on a dial I8, by a pointer II.

Figures and 16 represent, in elevation and in horizontal section on line I6-I6 of Fig. 15, respectively, a device for controlling the lateral displacement of the threads.

On the base plate 33 there is mounted rotatably the disk 34 having a pin 32'and adjusting wheels I4. 0n the disks 34 there are fixedstandards 35 carrying annular disks 30' in eccentric relation to the axle I and vertically above the center of the disks 34. The two disks 34 are connected together by rods 36. The tubes carrying the spokes Ii are fixed to the disk 30 and carry the drum bars on pivots 42.

Figure 17 shows diagrammatically a reel in which the lateral advance of the thread is produced by an endless carrier supported by rollers. The speed of advance of the thread depends on the ratio between the speed of revolution of the axle I and the threaded spindle I2, which drives the rollers 24. Thus, the advance of the thread may be made controllable by connecting the axle 1.
