1 In the manufacture of synthetic thread, or in the processing of synthetic or natural threads, a thread advancing device is used for causing the thread to move through a predetermined distance, during a predetermined time. One form of thread storing and advancing device includes a plurality of elongated, skewed rolls, and means for rotating said rolls about their longitudinal axes. The thread is applied to a device of this type by winding the end of the thread a few times about one end of said device. The operation of applying the thread to the thread storing and advancing device is referred to as lacing and one object of the invention is to produce improved apparatus for, and an improved method of, lacing a thread onto a thread advancing device.

In some instances, the thread advancing device includes a relatively large number of rolls and is supported at both ends thereof. To lace a thread onto a device of this type by manually winding the end of the thread around the exterior of all of the rolls is very difficult.

In other instances, the thread advancing device is supported in cantilever manner and the operator can stand near the free end of the device and can reach over and wind the thread as near to the other end of the device as possible. However, when a cantilever supported thread storing and advancing device is relatively long or has a relatively large diameter, or both, the lacing operation again becomes very difficult.

It is therefore a further object of the inven-v tion to produce an improved apparatus for, and method of, lacing the end of a thread onto a thread advancing device whereby the lacing operation is greatly facilitated, regardless of whether the thread advancing device is supported at both ends or not and regardless of the length or of the diameter of such device.

. A still further object of the invention is to produce an improved lacing apparatus which is semi-automatic, which is inexpensive, which is durable and which can be operated with minimum skill and effort.

. When the relatively large number of thread storing and advancing devices which are used contribute very materially to the advance of the industry.

vice and my improved method of lacing are car ried out will be understood from the following specification and the accompanying drawings in which;

Fig. 1 is a fragmentary and diagrammatic side elevational view of a thread manufacturing or treating apparatus embodying my invention, certain parts being omitted, the thread advancing and storing device being mounted in cantilever fashion. 1

Fig. 1A is a view looking in the direction of line lA-|A showing the parts omitted from Fig. 1.

Fig. 2 is an enlarged, fragmentary sectional view on line 11-11 on Fig. 1.

Fig. 3 is a fragmentary and diagrammatic view. looking in the direction of line III-III on Fig. 1, illustrating the ineffective position of the lacing device embodying my invention. 5

Fig. 4 is similar to Fig. 3 showing the effective position of the lacing device.

Fig. 5 is an elevational view showing a form of linkage for actuating the lacing device from one of its positions to the other. Fig. 6 is similar to Fig. 1 except that it shows the application of the invention to a thread manufacturing or treating apparatus of the type in which the thread storing and advancing device is supported at both of its ends.

A synthetic thread manufacturing apparatus of the type shown in Fig. 1 includes a supporting frame l0, an inner end plate 12 carried by said frame, a central fixed post [4 carried by said end plate, an outer end plate [6 carried by said fixed post, and a plurality of rolls, RI R2, R3, R4, R5, R6, R1 and R8, arranged in a circle aboutthefixed post l4 and having their ends journalled for rotation in self aligning. bearings l1 provided in said plates 12 and I6. Gears [8, driven by a motor M serve to rotate the rolls about their axes.

The axes of some or of all of the rolls are skewed with reference to the axisof'the center post M so that a thread laced about one end of the thread advancing device will, when said rolls are rotated, advance in a spiral path until it reaches the opposite end of said thread storing and advancing device. The assembly thus far described constitutes-a thread storing and advancing device which may form part of a continuous process synthetic thread manufacturing apparatus or which may be used for processing synthetic or non-synthetic threads. In the embodiments of Figs. 1 and 6. the axes of tharolls areso skewed. that a threadlaced about the thread advancing device will move from right to left as viewed in the drawings.

When the apparatus is used for the manufacture of synthetic thread, a spinnerette I9 is used for emitting an appropriate solution into a precipitating bath 2!! to form a filament 22 which ispassed over one or more godet wheels 24. After leaving the go'det wheel, the filament is wound about the right hand end of thethread advancing device and the rolls are rotated to cause the filament'to move spirally from right to left rela tive to the rolls Rl to R8.

In order to provide for easy and expeditious lac- The ring 26 is. located nearthe centrics, selectively, to the position of Fig. 3 or to the position of Fig. 4,

In Fig. 6 I have shown the application of the invention to a thread storing and advancing de vice which is supported at both oi its ends instead of being cantilever mounted as shown in Fig. 1. Since the structure of Fig. 6, except for having; a supporting frame! Ill" at each end thereof, is identical with thestructure of'Figs. 1 to 5, it is deemed unnecessary to describe the structure again.

From the-foregoing it will be seen that, to lace a thread onto the thread storing and advancing device; it. is merely necessary to turn the excentries 38' to-the position of Fig. 4 and to drop the 'endof thefilament-onto the rotating flat ring 26. i As. soonvas a. satisfactory bundle 28 has been 1 formed, it is pushed onto the thread storing and advancing device and is rotated so that, ;when-the.- 5

end of the filament is dropped onto the ring, the thread will form a bundle 2'8 around-the ring. 'llhabundlathus formed is pushedoff the ring and ontozthe adjacent end-of the thread-advancing da vice. Due to the skewing of the rolls, the bundle 28will movev from right to leftand the trailing filamentxwill vform: a single file spira1 30rwhichciroumscribes the rolls. and; which moves: longitudtof: the: thread: advancing device. When the bundle 2-8'has reached-the left'ha-nd end of the thread advancing device, it is out and removed and the trailing, endof. the filament is threaded V onto-4a coning, twisting, or other. take-up device notrshown In order to prevent the'filament from entering between the ring 2:6: andthe; end plate 12; the. ring is' provided with. are outer vertical guard; 32., The ring: is prevented: from lateral movement by any'suitablemeans-such as; an inner, vertical, flangev 3t which is disposed? in the spaca'between. theend; plate [2- and the a'dj acent ends of the rolls Rl to R8,...
