BEAM WARPER OR THE LIKE WITH THREAD I GUIDE COMB-FOR MULTI-LEVEL cREEI-L Filed June 1. 1966 United States Patent 4 Claims. til. 28-54) ABSTRACT OF THE DISCLOSURE The improvement in a beam warper and a multi-level creel therefor, the warper having a thread guide comb and thread deflector means spaced therefrom, the thread guide comb having aligned groups of tine pins, the tine pins in each group being equal in number to that of the creel levels, and having respectively different lengths, includes a thread deflector bar extending parallel to and spaced from the comb at the rear of the comb relative to the thread travel direction and intermediate the comb and the thread deflector means, the creel having means providing a deflection point for the threads passing from the creel to the bar, each of the tine pins having its tip located above the straight geometrical line connecting the deflection point at the corresponding creel level with the bar, the tip of each time being located below the corresponding geometric line relating to the next higher creel level.

My invention relates to beam warper or the like with so-called step-type thread guide comb for multi'level creel. More particularly, the comb of the invention relates to the type having groups of tine pins equal in number to the number of creel levels, the time pins of each group having respectively different lengths.

As is known, the threads extending from the creel to the beam warper are guided in so-called thread guide combs so that they run up onto the warper beam with a predetermined clearance or spacing there/between. The placing of the threads into these combs has heretofore been effected by hand and, in fact, most of the threads extending like converging rays to the comb from a vertical creel row of wound thread spools are individually laid into the spaces between the tine pins of the combs. To facilitate this laying-in work, there has been proposed heretofore that the tines of the combs be made of different lengths so that each respective group of tines corresponds to a level of a respective different height in the creel rows of thread spools or the like. For example, if the creel has eight levels of thread coils, then eight threads respectively extend from one vertical creel row. They converge like rays toward the beam warper, the thread extending from the uppermost level of the creel being laid into the thread guide comb between the longest and the next longest tines thereof, the thread extending from the creel level next to the uppermost level being laid between the second longest and third longest tines of the comb, and so forth. In spite of this facility achieved by this so-called step-type comb, the laying-in of the thread is nevertheless very toilsome and requires a great amount of skill. In practice, the so-called step-type comb of the construction known heretofore has therefore only had significance as a means for optically subdividing effectively the individual thread arrays so that when a thread break occurs a better view of the sequence or order of the laidin threads can be obtained when the broken threads are replaced.

It is an object of my invention to facilitate the layingin of threads into a comb of a beam warper or the like.

With the foregoing and other objects in view, I provide in accordance with the invention an improvement in a beam warper and a multi-level creel therefor, wherein the warper has a thread guide comb with aligned groups of tine pins, the tine pins in each group being equal in number to that of the creel levels and having respectively different lengths. The improvement comprising a thread deflector bar extending parallel to and spaced from the comb at the rear of the comb relative to the thread travel direction. The creel has means providing a deflection point for the threads passing from the creel to the bar, each of the tine pins having its tip located above the straight geometrical line connecting the deflection point at the corresponding creel level with the bar, the tip of each tine being located below the corresponding geometric line relating to the next higher creel level.

The features which are considered as characteristic for the invention are set forth in the appended claims.

Although the invention is illustrated and described herein as embodied in beam warper or the like with thread guide comb for multilevel creel, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.

The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of a specific embodiment thereof when read in connection with the accompanying drawing, in which:

FIG. 1 is a diagrammatic side-elevational view of a beam warper and creel assembly in accordance with my invention;

FIG. 2 is an enlarged view of a fragment of FIG. 1 showing the comb and deflector bar of the invention; and

FIG. 3 is a front view of FIG. 2.

Referring now to the drawing and first particularly to FIG. 1 thereof, there is shown a beam warper 1 facing two rows 21, 22 of thread coils in a creel 2. Individual threads from the creel 2 extend over the deflection points 3a to 3] through a thread guide comb 4 and over a deflector bar 5 to the warper beam 8.

In FIG. 2, there is shown in enlarged view the comb 4 and the thread guide or deflector bar 6, omitted from FIG. 1, which facilitates the laying-in of the thread in the comb 4. The deflector bar 6 is securely mounted in a holder 7 which is in turn secured to the back or ridge 4a of the comb 4. The comb ridge or bar 4a is readily seen in FIG. 3 as supporting the individual comb tines, which may be secured thereto by any suitable means. In the particular embodiment shown in FIG. 3, there is provided a step-type comb for a creel with six levels, six tines being provided for each level group; namely the tines 41 to 46 belong to the level group A, the tines 47 to 52 belong to the level group B and so forth. Furthermore, the deflector bar 6 is secured, as shown in FIG. 3, to the comb bar or ridge 4a by means of the holder 7 so that the deflector bar 6 is located behind the step-type comb 4 as viewed in FIG. 3.

For laying-in the threads from the creel into the comb 4 of the beam warper 1, the threads respectively of one vertical row of the creel, for example the row 21, are seized or gripped and are placed together above the thread deflector bar 6. The threads extending from the individual levels of the creel pass then in suitable straight paths from the respective deflection points 3a to 3) at the creel 2 to the thread deflector bar 6. In principle then, there is produced, as is easily recognizable in FIG. 2, the indicated ray-like thread distribution formed by the thread lines 6a to 6 However, in FIG. 2, the lines 6a to 6f are more widely spread relative to one another so as to more clearly show the converging relationship thereof. As is further shown more clearly in FIG. 2, in accordance with the invention, the tines 41 to 46 of each level group are of such predetermined length that the point of each tine lies both above the straight connecting line or thread portion from the deflection location of each thread at the creel to the thread deflection bar 6 and also beneath the straight connecting line or thread portion to the next higher creel coil level. That is, the tip of the tine pin 46 is above the connecting line or thread portion 6 but below the connecting line or thread portion 6e. Also the tip of the tine pin 45 is above the connecting line 6e but below the connecting line 6d, and so on for all the remaining pins and connecting lines. Thus, by means of the thread deflector bar 6, it is assured that the rays of threads extending from the creel to the beam warper will always remain in the same position. Consequently, it is particularly advantageous for facilitating the laying-in of the thread between the comb tine pins, for the spacing of the thread deflector bar 6 from the step-type comb 4 to be of such selected dimension that the difference in length of the adjacent tine pins of the comb, that is between the

pins

45 and 46 on one hand, between 44 and 45 on another hand, and between 43 and 44 on still another hand, and so forth, is at least 2 mm. It is furthermore advantageous with respect to the laying-in of the thread in the comb, that in accordance with a further feature of the invention, the dilference in length between the next-tolongest tine pin 42 and the longest tine pin 41 of each level group is greater than between the other tine pins of a level group, as can be seen quite clearly from FIGS. 2 and 3.

The laying-in of the thread extending from the creel into the step-type comb occurs in the following manner:

The threads extending from coils located one above the other in a vertical row of the creel 2, for example the row 21, are grasped, by hand for example, and placed substantially in the direction of the arrow 10, as shown in FIG. 3, against the longest tine pin 47 of the adjacent level group B and then permitted to slide down onto the lay-up or deflector bar 6 as shown in FIG. 2. Thus, the positions indicated by the dots 61 to 66 are assumed by the individual threads as shown in FIG. 3. Then the entire thread array is passed to the left in the direction of the arrow 11 toward the increasingly longer time pins. Thus the individual threads are automatically hung in the spaces between the tines provided therefor. That is, the thread 66 lying at the lowest level remains hanging in the space between the longest time pin 47 of the adjacent level group B and the shortest tine pin 46; the thread 65 passes into the space between the tine pin 46 and the next longer tine pin 45; the thread 64 passes into the space between the tine pin 45 and the next longer tine pin 44, and so forth until the thread 61 passes into the space between the tine pin 42 and the longest tine pin 41 of the level group A. When all of the threads are then loosened or when the thread array slides down farther, the laying-in operation of the thread array of a vertical row of the creel is thereby completed in only a fraction of a second.

As soon as all the threads are laid in the individual levels A, B and so forth of the step-type comb in this manner, the threads are passed over the deflector or reversing roller 5 to the warper beam 8. The thread deflector bar 6 can consequently be removed, for example, by being slid down, detached, pulled out or the like. It is however also possible to form the deflector edge of the deflector bar solely as a thin rod mounted laterally or transversely to the thread array. The individual threads of the creel can be passed beneath the deflector edge of such a deflector bar during the operation of the warper. Independently of the fact that the thread deflector bar 6, during operation of the beam warper, is removed or is not removed, the path of the thread array is restricted, during the operation of the beam warper, between the dot-dash lines 9a and 9b of FIG. 2.

By means of the invention, it is possible to reduce the 4 laying-in time of the threads in the warper comb to fractions of the time necessary heretofore for laying-in the threads. Furthermore, it has rendered superfluous the necessity for servicing personnel to learn by special instruction how to carry out this laying-in operation since this laying-in can be effected virtually blindly with a minimum of manipulation. Consequently, the invention is suitable not only for beam w-arpers, broad drum warpers and the like, but rather for laying-in all threads extending in a converging ray-like array on a thread guiding comb.
