No. 55,241 Claims priority, application Germany Sept. 14, 1959 20 Claims. (Cl. 242-131) the form of strand lap units or thread lap units depends on the number of the working stations available in the machine and the type of processing which is provided at each working station for a strand or thread or a plurality thereof as feed. In this connection there exists the minimum requirement that at least one fiber strand or thread must be fed to each working station. Furthermore, it is required that the bobbin feed has as long a running length as possible which means that the bobbin must be of such large dimension that the size of the bobbin will not cause any qualitative faults in the prodduct to be processed while on the other hand it will not prevent each individual bobbin and all of the bobbins mounted on the creel from being properly handled individually.

While the heretofore known creels with boards, bars, ledges, or the like, extending in the longitudinal direction of the respective machine for mounting bobbin holders are able to meet the above mentioned requirements at least partially, they have as a rule always caused certain drawbacks concerning a proper simple andconvenient handling of the bobbins as soon as either the number of the bobbins or the size thereof becomes so great that it was not possible any longer so to mount the bobbins on the creel that they could easily be observed. This was particularly the case when the spacing from working station to working station of the machine was narrow which means that the available space for the mounting of the bobbins or the bobbin feed is small. The said drawbacks are most apparent when mounting the bobbins by means of creel pins or creel spindles. This is due to the fact that in such an instance the lower as Well as the upper end of the bobbin has to have a long holding member extending in longitudinal direction of the machine for receiving the foot and the upper end of the said spindles or pins which assure a stationary position of the bobbins. A similar situation prevails also with the so-called spindleless mounting, and to a certain degree also with the mounting by means of suspended bobbin holders. Even though with these known mounting types a bobbin feed of larger bobbins can be provided by arranging the bobbins in a plurality of rows one after the other or one above the other, the difiiculty as to handling the bobbins still prevails because the rear row of bobbins arranged behind each other or the upper row of bobbins arranged above each other as a rule are diflicult to get at. In this connection it should also be borne in mind that the size of the bobbins has increased not only as to their diameter but also as to their length which makes the handling of bobbins in a creel with stationarily arranged bobbin receiving members considerably more difiicult. The increase in the dimensions of the bobbins is, however, desired on one hand in view of the obtained higher working speeds to thereby cut down the time interval from mounting to mounting of a new bobbin, at least as far as the heretofore known relationship to the working speed of 3,055,610 Patented Sept. 25, 1962 the machine is concerned. On the other hand, an increase in the dimensions of the bobbins is also favorable with the heretofore customary working speeds because the time interval from one mounting to another mounting of a bobbin becomes greater so that the operator will have more time available for other operations at his machine with the respective working stations, or the operator will be able to take care of a greater number of working stations without aifecting the total result.

It is, therefore, an object of the present invention to provide a creel which will overcome the above mentioned drawbacks.

It is another object of this invention to provide a creel which will make possible the mounting of bobbins of greater dimensions with regard to diameter and length than heretofore while nevertheless assuring the possibility of properly handling such bobbins, especially those having a greater distance from the operators station.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

(FIG. 14 is a view partly in section-showinga carriage adapted to be inserted into stationary guides of a creel and comprising a C-shaped holding arm for receiving a can with inserted fiber strand lap.

FIG. 15 is an elevation partly in section of a C-shaped holder having its lower transverse leg provided with supporting or bearing means for rotatably mounting thereon a disc or disc-shaped plate adapted to receive at least one cake-shaped fiber lap.

FIG. 16 is an elevation partly in section ofan L-shaped carriage having its vertical leg provided with hinged arms General Arrangement The objects outlined above have been realized according to the present invention by mounting on the creel or holding member stationary guides extending transverse to the creel or holding member for receiving carriages carrying at least one bobbin holder, each of said carriages being adapted individually and whenever required to be moved from the normal working position of the bobbins into a servicing position easier accessible to the operator, which carriages may be returned from the servicing position to their normal working position.

Such an arrangement yields the great advantage that the ordinary working position of the bobbins is not any longer to be fixed or stationary which means that each bobbin can be moved into a servicing position which allows a handling of the bobbins or servicing of the bobbin holders from a plurality of sides without in any way afiecting the ordinary working or feeding path of the fiber strand or thread from the respective bobbin.

Advantageously, the arrangement is such that the carriage guides on the holding member are spaced from each other by a distance corresponding to the number of bobbins said carriaige may be able to receive and support. The smaller the number of bobbins to be supported by a carriage, the better will be the accessibility and serviceability in the working position and in the servicing positon.

The guides for the carriages may, of course, be designed in various manners. Thus, each of the guides may consist of a plurality of mutually spaced ears, L-shaped angles, or the like, connected to the holding member. It is furthermore possible to make each of said guides in the form of a long rail, bar or the like connected to the holding member. If particularly long movements of the carriage are desired, each of the guides may be composed of at least two telescopically engaged and displaceable bars, rails, or the like, one of which is connected to the holding member. A still more favorable construction will be obtained if each of the carriage guides consists of at least one L-shaped angle angled off downwardly from the holding member in transverse direction thereof.

The various possibilities mentioned above will at any rate assure that the carriages provided with bobbin holders will individually be movable in said guides toward the servicing side of the machine.

The carriage supporting said bobbin holder, particularly in conformity with the creel according to the present invention, may, of course, be designed in various manners. Common to all modifications is the feature that the carriage comprises a holding arm adapted to receive at least a fiber strand or thread lap unit in a suspended manner or without a mounting spindle. According to one of the various possible modifications, the holding arm of the carriage is designed as straight bar, rail, or the like, on which a bobbin holder for an individual bobbin may be suspended. Furthermore, it is possible to design the holding arm of the carriage in a C-shaped manner and to mount a suspended bobbin holder each at the upper and lower transverse arm in such a way that two individual bobbins will be suspended one above the other.

A further development of the present invention consists in designing the holding arm of the carriage in an I-shaped manner and suspending a bobbin holder each at the two ends of the transverse arm in such a way that two individual bobbins will be arranged one behind the other in suspended manner. It is furthermore possible to design the holder of the carriage in a double T-shaped manner and to suspend one bobbin holder each at the two ends of the upper transverse arm and at least a further bobbin holder at the lower transverse arm in such a way that at least three individual bobbins will be suspended above each other in two groups.

Also the bobbin mounting without spindles allows a number of variations of the carriage. Thus, the holding arm of the carriage may be designed in a C-shaped manner and receiving means each for the lower and upper end of a bobbin sleeve may be mounted at the ends of the transverse arm in such a way that the individual bobbin will be arranged without spindle. Furthermore, there exists the possibility of designing the holding arm of the carriage in an E-shaped manner and to mount one receiving member each for the lower and upper end of a bobbin sleeve at the ends of their respective superimposed transverse arms in such a way that two indiivdual bobbins will be arranged without spindles one above the other.

It is furthermore possible to design the holding arm of the carriage in a double-T-shaped manner and to provide one receiving means each for the lower and upper end of a bobbin sleeve at the two ends of the respective transverse arm in such a way that two individual bobbins will be arranged without spindles one behind the other.

As will be evident from the above, one of the various possibilities will be adapted at any rate for the most favorable arrangement of the creel in conformity with the respective prevailing conditions of operation. In this connection it is also to be understood that the term individual bobbin is intended to cover a bobbin with a single strand, as for instance a fiyer bobbin, and also a bobbin with a double strand, as they may be wound for instance upon a cylindrical form of a finisher of the worsted yarn pie-spinning art.

For purposes of guiding the strand or strands or threads between the bobbin and the receiving roller pair of for instance a drafting system, the customary and known strand guiding means in the form of long bars or individual pigtail guides may be employed. Furthermore, a strand guide with one or two strand guiding members may be mounted on the longitudinal arm of the holding arm so as to be adjustable as to height. According to a particularly favorable construction of the present invention, the length of the longitudinal arm of the holding arm is by means of a strand guide engaging said arm adjustable and arrestable. In this way, simultaneously with the guiding of the strand, also the position of longitudinally adjustable longitudinal arms of the carriage will be assured so that the arrangement may in a single manner be adapted to bobbin sleeves of different length. A further possibility for the design and employment of the carriage consists in that the holding arm of a carriage is designed in a C-shaped manner and that a can with inserted fiber strand lap is adapted to be placed upon the lower transverse arm. It is furthermore possible to design the holding arm of the carriage in a C-shaped manner and to provide the free end of the lower transverse arm with receiving means adapted rotatably to receive a plate for at least one cake-shaped fiber strand lap. This last mentioned arrangement makes possible the employment of a creel according to the invention also in connection with a two cylinder spinning arrangement, this all the more inasmuch as the tendency in this particular arrangement aims at making the path of the bobbin feed as long as possible so that while heretofore the winding off of a vertical cake-shaped fiber strand lap might lead to difiiculties, such difiiculties can not occur when employing a carriage according to the invention because the cake-shaped fiber strand lap rests in horizontal position upon said plate.

Similarly, the creel according to the invention may also be employed in connection with the unwinding of cakeshaped thread laps which are delivered in practic by modern bobbin machines. A construction of the carriage suitable for this purpose provides that the holding arm of the carriage is C or E-shaped or equipped with further transverse arms while the uppermost transverse arm is connected to the longitudinal arm. The transverse arm or arms arranged therebelow are mounted on the longi a 5 tudinal arm in superimposed position and are each tiltable individually. The respective free ends of these transverse arms are provided with receiving means adapted rotatably to receive a dish or plate for at least a cake-shaped thread lap".

A spinning machine equipped with a creel according to the invention regardless of whether intended for prespinning, fine-spinning, reeling, or twisting, will meet the above mentioned requirements with regard to the maximum dimensions of the bobbins and also with regard to the ease and speed of operation desired. This applies to individual bobbins as well as to the entirety of the bobbins mounted on the creel. The diameter of the bobbins may now be selected so great that for instance two bobbins arranged adjacent or behind each other will have their outer circumference ahnost in contact with each other. The increase in the bobbin length is even when arranging the bobbins one above each other of no disadvantage as to the possibility of handling said bo bins because the creel may be arranged so low that the bobbins arranged in the lower bobbin row will have at least a portion of their length below the drawing-in roller. With a heretofore customary creel, such an arrangement would considerably handicap the handling of the drawing-in rollers. However, with a creel according to the present invention such an arrangement of bobbins within the range of the drawing-in rollers is no handicap at all because by displacing the carriage with the bobbin'ho-lders thereon, any part can easily be made accessible.

These advantages present themselves already with machines of customary width to a great extent and become even more favorable the less the width of the machine. Inasmuch as the tendency to reduce the width of the machine already plays an important role in-practice, it is particularly in such instances that the creel according to the present invention will best meet the above mentioned requirements without entailing any drawbacks.

Structural Arrangement Referring now to the drawings in detail, the arrangement shown in FIG; 1 illustrates a two-side ring spinning machine equipped with a creel according to the invention. The left machine side as well as'the right machine side is equipped with a drafting mechanism comprising a pair of feed rollers or drawing-in rollers 1 as well as'with machine columns 2. These columns 2 are, in a manner known per se, arranged at the central longitudinalbeam of the machine which has been indicated in-the drawing only below the drafting mechanism. The machine columns 2 form the pillars for the creelwhich latter cmprises a cantilever 3 extending to both sides of a machine column 2 and which further comprises the creel boards 4 and 5 connected to arm 3 and forming the holding members.

According to the creel of the present invention, guiding means are stationarily arranged on said holding members and extending transverse thereto. Displaceably mounted in said guides are carriages which are individually displaceable and provided with at least one bobbin holder. According to the arrangement of FIGS 1 and 2, the creel board 4 as well as the creel board 5 are provided with guiding rails 6 having a hollow profile and a downwardly opening slot. Reciprocably mounted in the hollow profile of each guiding rail 6 is a carriage '7, 8 which in the embodiment illustrated is designed for spindleless mounting of two individual bobbins one behind the other. The guiding rails 6 are mounted on the creel boards 4 and 5 serving as holding members and extending in longitudinal direction of the machine. The said guiding rails 6 are arranged in spaced relationship to each other in such a way that the distance between the gniding-railso in the particular embodiment shown corresponds to two spindle spacings because

individual bobbins

9, 10, 1'1 and 1 2 with single strand are involved. In

this way, the diameter of an individual bobbin may be selected almost as large as the magnitude of two spindle spacings because regardless of such a large diameter of the bobbin, an easy accessibility and serviceability of the bobbins will be assured by the design of the creel according to the invention.

As will be evident from FIG. 1, the carriage 7 with the

individual bobbins

9 and 10 occupies its normal working position above the drafting mechanism while the carriage 7 is fully moved into its guiding rail 6; In contrast thereto, the carriage 8 with the individual bobbins 1 1 and 12 occupies its servicing position, which means that the carriage '8 has been pulled outwardly toward the servicing side of the machine so that the individual bobbin 10 is freely accessible from the servicing aisle. Also the individual bobbin 11 may be moved into a position which will assure suflicient and easy accessibility for any handling thereof. Inasmuch as each of the guiding means may be designed as two telescopically displaceable guiding rails 13 and' 14 in the manner shown in FIG. 3, the extensibility of for instance the carriage 8 may be further increased whereby also the accessibility to the individual bobbins 11 will be improved.

Already the above discussed embodiment illustrates that the requirements previously set forth as to be met by a modern creel of spinning machines will be met in every respect. With regard to the design of the details, there exist, of course, various possibilities. .Thus, for instance, the guiding means may consist of a plurality of spaced hooks, ears, L-shaped angles or the like connected to the respective holding member 4, 5-. I'he carriage will then be di-splaceably mounted in said hooks, ears, L-shaped angles or the like. Generally, the guiding means are arranged in such a way that they form an angle of approximately to the longitudinal axis of the creel boards 4 and 5. However, it is also possible to vary this angle so that it will amount to less than 90 in which instance the pulling out of the carriage toward the servicing side of the machine will be eifected along a more or less diagonal path while the advantages outlined above will still be retained.

It is furthermore possible slightly to incline the guiding rails 6 or the telescopically inter-engageable guiding rails '13 and 1 4 or other guiding means toward the longitudinal central plane of the machine in order to prevent the carriage with its bobbin holders from accidentally, for instance by vibrations of the machine, leaving its working position as it is shown in FIG. 1. It is also to be understood that instead of the

individual bobbins

9, 10, 1 1 and 12 mounted on the carriage 7, 8 also'bobbins with double strand may be employed so that in such an instance two double strand bobbins mounted for instance on the carriage 7 would deliver their fiber'strands to four drafting fields of the drafting mechanism. This means that in such an instance also the diameter of each double strand bobbin could be enlarged correspondingly while nevertheless the accessibility to the bobbins would be retained to its full extent in view of the fact thatthe carriage can be pulled out.

, FIG. 4 shows a further embodiment of a creel according to the invention. In this instance the holding member extending in longitudinal direction of the machine and the guiding means extending transverse to said holding member consists of one and the same piece. The arrangement is such that each of the guiding means consists of at least one L-shaped angle member angled off down wardly. from the holding. member itself. Mounted on the machine columns 2 are supporting arms 3 extending to both sides, similar to the arrangement in the previously described embodiment. With the arrangement according to FIG. 4, the holding member 15 serving as creel consists of a plate-shaped material as for instance sheet metal, or suitable synthetic material as for instance polyamides. The marginal portions 16 of the holding member 15 are rolled or'bent inwardly in order to impart the necessary strength to the holding member 15 extending from supporting arm to supporting arm. As will be evident from FIGS. to 7, L-shaped angles 17 are angled off from the holding member itself toward the bottom side of the holding member 15 so that in each instance two oppositely located angle pieces 17 forming an image to each other will serve as guiding means for a carriage with bobbin holders. It is furthermore possible to design each guiding means of an angle member of sufiicient length. It is, of course, more favorabl to employ the construction shown in FIGS. 5 to 7 according to which two angled-off angle members 17 and 17' extend over the Width of the holding member 15. Between each two angled-off L-shaped angle member 17 there is a wide web which will improve the rigidity of the holding member 15. Of course, if desired, three or more stampedout angles may be mounted over the width of the holding member 15 for creating guiding means for a carriage. If the stamped-out cuts and angles are effected at such a spacing which corresponds to a fraction of customary spindle spacings, it is possible to employ a holding member 15 designed in this way with guiding angles 17 on machines of different spindle spacings. If, for instance, the distance from center line to center line of the guiding means in longitudinal direction of the holding member amounts to 40 millimeters, the holding member 15 may be employed in connection with machines having spindle spacings of 80, 120, 160 millimeters etc. and serve as portion of the respective creel because in each instance guiding angle members 17 corresponding to the spindle spacing are availabl into which carriages with bobbin holders may be displaceably inserted.

The carriages insertable in the guiding means of various constructions may likewise be designed in various forms as illustrated already in FIGS. 1 and 4. In each instance a carriage is designed in such a way that it comprises a holding arm having suspended thereon or being adapted in a spindleless manner to receive at least one fiber strand or thread lap. The simplest embodiment would consist in a straight bar, rail or the like on which a bobbin holder would be suspended for an individual bobbin. If such a straight bar, rail or the like is inserted into guiding means of a corresponding profile, which guiding means may be mounted on a creel or board 4, a holding member 15 or other holding means extending in longitudinal direction of the machine, the bobbin suspended on the carriage will in each instance be movable from its ordinary working position into a servicing position which will be accessible from the servicing aisle considerably easier than the ordinary working position of the bobbins. For instance, the upper transverse arm of the carriage shown on the left-hand side of FIG. 4 may in itself correspond to the simplest construction of a carriage. In this way, a single row of individual bobbins for one machine side may be mounted on a creel.

The supporting carriage 18, illustrated on the left hand side of FIGURE 4, comprises a C-shaped holding arm, the upper transverse leg 19 of which, as well as the lower transverse leg 20, supporting each a bobbin holder 21 respectively suspended thereon. In this way, two individual bobbins can be mounted in suspended manner one above the other on the creel for supplying the material to be drafted. As will be evident from FIGURE 4, the space requirement of the bobbins is relatively small because, in addition to the relatively short extension in the depth of the machine, the extension of the creel as to height is very favorable.

As will furthermore be evident from the drawing, the individual bobbin 22 of the lower row of bobbins extends rather closely to the feed or drawing-in roller pair 23 in as much as the accessibility of this roller pair is assured in spite of the bobbin suspended ahead of the same, because the roller pair 23 may, at any time it is to be handled, be laid free by pulling out the carriage 18 and thereby moving away said bobbin 22'.

The right hand side of FIGURE 4 illustrates a carriage 24, the holding arm of which is T-shaped. Both ends of the transverse leg 25 of said carriage 24 support each a suspended bobbin holder 26 so that, in this way, two bobbins '27 and 27' may be mounted on the creel in suspended manner one behind the other. If, in addition to the transverse leg 25, the lower end of the longitudinal arm 28 has mounted thereon in any suitable manner an additional transverse leg (FIG. 4a), an I-shaped design of the holding arm will be obtained so that, in addition to the illustrated bobbin holders 26 with bobbins 27, said lower transverse leg could support at least a further suspended bobbin holder so that at least three individual bobbins could be mounted in superimposed rows as thread or strand (FIG. 4a). The location of a bobbin holder at the lower transverse leg could, of course, be effected in conformity with the respective requirements.

Similarly, at both ends of the lower transverse leg, there could be provided one suspended bobbin holder each for two individual bobbins.

The above described constructions of carriages for the suspension of bobbins may, of course, be adapted to the respective conditions of operation. Depending on the construction of the carriage guides for the carriages to be moved therein, and in conformity with the space available on the creel, and the size of the bobbins, the construction of the carriages may be varied as to the respective material of which they are made and also as to their cross sectional shape. Thus, it is possible, without difficulties, to produce the carriages of round stock, but naturally other profiles may be employed. Similarly, the carriages may be punched out of plate-shaped material and their upper edge could be so shaped that they will be displaceable in the guiding means on the creel. The plate-shaped material may be metal or synthetic material as, for instance, polyvinylchlorides.

FIGURE 8 illustrates the T-shaped carriage 24 of the right-hand side of FIGURE 4 on a larger scale. The said carriage 24 is punched out of a rigid plate of synthetic material and has its upper end provided with a suitable guiding means 29 which will assure a reliable support of the carriage 24 and the displaceability of said carriage in the guides 17' of the creel 15. Naturally, the carriage 24 may also be of different design. The selection of the material and of the cross-sectional shape may, of course, be adapted to the respective requirements.

For instance, the carriages 24 may be punched out of a light metal plate or steel sheet metal and may be provided with a suitable guiding profile.

Preferably, such materials are of metal which, on one hand, is resistant to the usual humidity in a spinning plant, and, on the other hand, will have as sm0oth a surface as possible in order to cut down to a minimum the possibility of dust or lint collecting thereon.

The C-shaped arm 18 shown on the left hand side of FIGURE 4 for the mounting of two suspended individual bobbins may, in almost identical shape also be employed for the spindleless mounting of an individual bobbin. This is possible without difficulties if, instead of the illustrated bobbin holder 21 supporting or bearing means (e.g. members 33 of FIG. 11) is provided for the upper end of a bobbin sleeve and if the free end of the lower transverse leg 25 is provided with supporting or bearing means aligned with said upper or supporting bearing means (e.g. members 35 of FIG. 11) aligned with said upper supporting sleeve (FIG. 4b). It will be appreciated that, with such an arrangement, it is possible, without difliculties, to mount the lower and upper end of a bobbin sleeve of an individual bobbin without a spindle between said two supporting or hearing means. If, instead of the c-shaped design of the holding arm, an E- shaped holder is provided and if supporting or hearing means for the upper and lower end of a bobbin sleeve are mounted on the ends of the respective transverse -legs arranged above each other, there exists the possibility of mounting two individual bobbins in Superimposed position without spindles (FIG. 40). Furthermore, it ispossible to give the carriage an I-shaped design and to provide one supporting or hearing means each for the lower and upper end of a bobbin sleeve at the ends of the respective transverse legs so that two individual bobbins can be mounted without a spindle one behind the other. Such a design is shown in FIGURE 1 and on a larger scale in FIGURE 11.

According to FIGURE 11, the I-shaped carriage 30, which corresponds to the carriages 7 and 8 in FIG- URE 1, is composed of two T-shaped sections 31 and which may have identical dimensions. The two sections 3 1 and '31 are arranged in such a way that they form an image to each other and they are connected to each other in any suitable manner. The thus-formed double I-shaped carriage 30 has the two ends of its upper transverse leg 32 provided with supporting or bearing means 33 each for the upper end of a bobbin sleeve. The two ends of the lower transverse legs 34 are each provided with supporting or bearing means 35 for the lower end of a bobbin sleeve. The design of the upper as well as of the lower supporting or bearing means for the spindleless mounting of bobbin sleeves may, of course be adapted to the various prevailing conditions without the necessity of exchanging the carriage itself. It is also possible to adapt the construction to various lengths of bobbin sleeves as is clearly evident from FIGURE 11. According to the particular embodiment shown in FIG- URE 11, the longitudinal legs of the T-shaped sections 31- and 31' are designed so as to overlap each other and are provided at uniform and identical distances with bores through which, after the carriage has been adjusted for the desired length, there will be passed suitable connecting elements for securing the two

sections

31 and 31 with regard to each other in the desired position. According to FIGURES 11 to 13, a strand or thread guide 36 is employed as connecting means for the T-shaped

sections

31 and 31. The member 36 is composed of substantially two identical members 36" and 36", each of which is provided with a thread or strand guide 37. The back side of the two members 36' and 36" is provided with two knobs 38 and two recesses 39 offset to each other on the two members 36' and 36" so-that the knobs 38 of one of said members 36' and 36 will engage the recesses 39 of the other member when both members are inserted in corresponding bores for connecting the T-shaped portions 31 and'31'. If in this connection, thebores are provided with a unilateral slit extension the width of which corresponds to the diameter of the stems carrying the knobs 38, it will be appreciated that after pas-sing through the knobs 38 of the twosections 36 and 36" and after subsequently pulling the two T- shaped parts 31 and 31' away from each other, the said two parts 31 and 31' will maintain their position and thereby the adjusted length of the longitudinal arm in conformity with the length of the respective bobbin to be mounted; In addition thereto, it is nevertheless possible to adjust the strand or thread guides 37 as to height which guides are mounted on carriage 30. In thisway, the guides 37 may be arranged at the most favorable level with regard to the bobbins and also with regard to the feeding or drawing-in rollers of the drafting mechanism.

FIGS. 8. to illustrate a similar construction of a thread or strand guide. However, according to FIGS. 8 to 1-0, the strand or thread guide 40. comprising the two sections 40* and- 40". serves exclusively for guiding the strand or thread and is not intended for connecting the two legsections- Alsoin this instance it is possible to adjust the strand or thread guide so as to cause the same to occupy the most favorable position with regard to the bobbin. This adjustment is effected by passing the If two sections 40' and 40 into corresponding bores of the longitudinal leg 28.

Further embodiments of a carriage for mounting bobbins with different supply on a creel are shown in FIGS. 14 to 16. FIG. 14 illustrates a carriage adapted to be inserted into the stationary guides of a creel, which carriage comprises a C-shaped holding arm 41 having its lower transverse leg arranged for receiving a can 42 with inserted fiber strand lap; A feed of fiber strands in cans is. known per se in connection with spinning machines, however, the employment of carriages 41 makes possible the mounting of such feeds in cans on ordinary creels if these are designed in conformity with the present invention and if the creels are provided with corresponding guides. The lower transverse leg 43 may, of course, be shaped in conformity with the shape of the can. In the example illustrated in the drawing, the lower transverse leg 43 is provided with a holding edge 44 engaging a corresponding edge of the can 42 so as to secure the posi tion of can 42 as soon as at the upper edge of can 42 an extension 46 adjustable as to height will engage the longitudinal leg 45. If desired, the lower transverse leg 43 or the edge 44 thereof may be designed in form of a plate fitting the depression in the bottom of can 42 in which instance the extension or catch 46 would be superfluous.

FIG. 15 likewise shows a C-shaped holder 47 having the free end of its lower transverse leg 48 provided with supporting or bearing means 49 for rotatably mounting thereon a disc or dish-shaped plate '50. Said plate 50 is adapted to receive at least one cake-shaped fiber lap for withdrawing the thread or strand therefrom. In this way, it is possible to mount on the creel also the cake-shaped bobbin feed of the two-cylinder spinning art. This arrangement represents a favorable way of mounting the cake-shaped bobbin feed and also represents a more gentle treatment of the lap which, due to the fact that it rests horizontally on plate 50, will be subjected to con siderably less stress than would be the case if said lap has to be unwound in the heretofore known manner over its entire circumferential surface from start to end of the lap;

The cake-shaped lap units as furnished by modern Winding machines may without difficulty be mounted on a creel for withdrawing the strand or thread therefrom if a holding arm 51 in-.conformity with FIG. 16 is employed. Such holding arm 51 may be 0- or E-shaped or may be provided with additional transverse legs while'the uppermost transverseleg which is to be passed into the guiding members of the creel is fixedly connected tothe longitudinal leg 52, whereas the

transverse legs

53, 54 and S5 therebelow are each tiltably mounted on the longitudinal arm 52 and have their respective free ends provided with supporting or hearing means 49 on which similar to FIG. 15 a dish shaped plate' 56 is rotatably mounted. At least one cake-shaped lap will in horizontal position rest on each of the plates 56. In this way, a'proper thread'or strand'feed will be obtained by means of an easily accessible creel for instance for use in connection with twisting machines. When employing carriages'of the type illus trated in FIGS; 14 and 16, there exists the further possibility of doubling the fiber strands or threads in a required number, especially when the carriages are designed accordingly.

Of course, also in the last mentioned instances the carriages movable by means of theirupper legs in the guides of the creel are so designed that the position of the carriages in the guides will be properlysecured but that there will also-be possible a slight displaceability. With all above mentioned and describedembodiments, a slight play may be provided between the carriages and the guiding means therefor in order to allow said carriages with thebobbins mounted thereon to adjust themselves to the most favorable position which may for instance be brought about by the pull of the strand or thread being withdrawn from the bobbin. It is furthermore possible in certain instances to do without the displaceability of the carriages within the guides. In other words, the above mentioned carriages may in certain instances be arranged stationarily or so as to be able to carry out a pendulum movement about their upper transverse legs and may be mounted on the longitudinally extending holding member of the creel. The various carriages described above may also form a part of the creel.

It is, of course, to be understood that the present invention is, by no means, limited to the particular constructions shown in the drawings but also comprises any modifications within the scope of the appended claims.
