Abstract

Apparatus having opposable, relatively oscillating surfaces between which the overlapped ends of bundles of fiber strands or slivers are placed for splicing. The splice produced is characterized by the tangling of generally parallel fibers resulting from the action of a component of the oscillation transverse to their direction, and also from the presence of crimp in the fibers.

INVENTOR THOMAS E. M RINER SPLICER FOR NONWOVEN FIBERS BACKGROUND OF THE INVENTION The field of this invention generally relates to the manufacture of yarn. More particularly, it relates to means for splicing or hitching together the nonwoven, nontwisted fibers, strands or slivers as they pass through the stages of the manufacturing process from the preliminary state (the greasy state in the case of wool, for example) to the finished yarn.
The fibers, strands or slivers, which pass through a sequence of carding machines, fiber drafting and combing machines, frequently break at various points in the sequence, which necessitates constant attendance by machine operators. Several methods for splicing have been employed but have been found objectionable for various reasons. One method is to tie the ends to be spliced with a knot. While a knot has sufficient strength to carry the fibers into a fiber-drafting machine, also called a pin drafter or a gill box, it cannot pass successfully through the machine and has a tendency to pull out its pins or otherwise cause machine damage. A further objection is that a knot introduces a defect in the form of neps in the fibers that may require removal at a later stage of manufacture. Machines of this type are generally inoperative with most kinds of knots.
Another splicing method requires the use of an adhesive to join the fiber ends. This also tends to result in defects and has other disadvantages.
A third method, which can be performed successfully, is to overlap and hold together the leading and trailing ends of the fibers to be joined, and to hand-feed them as they enter the next processing machine in the sequence. However, this method is not reliable because it may result in machine damage when incorrect practices are employed in overlapping the strands.
Fibers of wool, for example, have a diameter generally between 18 and 34 microns, and also possess a natural crimp. Ideally, such fibers should be spliced by a straight-line tangle that is by overlapping them while maintaining them in closely parallel positions, causing them to tangle as a result of their close proximity and the mutual engagement of their crimps. This should be accomplished with minimum fiber breakage and minimum formation of neps or conditions leading to an increase in the nep count. The strength of the splice should be adequate to carry the fibers into the next succeeding machine. Moreover, the splicing should be accomplished with speed to avoid a machine shutdown.
Similar criteria apply to the splicing of other kinds of fibers, either natural or synthetic, and whether the crimps are naturally occurring or synthetically produced.
The methods hitherto commonly used in splicing are heavily dependent on manual steps and fail to satisfy many of the foregoing criteria.
SUMMARY OF THE INVENTION This invention provides novel apparatus capable of satisfying the criteria for ideal splices on natural and synthetic fibers, strands and slivers which for purposes of the following description are referred to simply as fiber bundles. This apparatus is preferably hand-held and includes a pair of opposable pressure plates and drive means for causing relative oscillation of the plate surfaces. The fiber bundles to be spliced are overlapped and placed between the plates which apply pressure to the fibers transversely to their direction of extent while providing an appreciable component of oscillatory movement that is perpendicular to both the direction of the fibers and the direction of the applied pressure.
This apparatus rapidly performs a splice of sufficient strength for the above purposes, without making knots or significantly increasing the nep count. Any defects produced by the machine are generally of such nature that they can be gilled out in one pass through a fiber-drafting machine. Splicing may be performed without stopping the machine, thereby tending to facilitate a more fully automatic manufacturing process.
This apparatus takes full advantage of any available crimp in the fibers and also any lateral surface protuberances, irregularities and discontinuities thereon, such as the serrations on wool fibers, whether naturally occurring or artifical, to give strength to the splice. It also does not break the fibers.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a side elevation of a preferred embodiment of the invention of the open position.
FIG. 2 is a similar elevation showing the same embodiment in the closed position.
FIG. 3 is a detail elevation showing the positions of the fibers to be spliced in the closed machine.
DESCRIPTION OF THE PREFERRED EMBODIMENT The apparatus of FIGS. 1 and 2 is supported on a metal frame 12 which may be hand held by a handle 14 attached thereto by a bolt and nut 16. The frame may be fabricated in any convenient manner and may comprise one or more parts fastened together by welding or in any other convenient way. The bottom of the frame comprises a rectangular baseplate 18 at one end of which is an integral backplate 20 for fastening the handle, braced by side gussets 22. These latter have holes for pivotally attaching a pair of arms 24 by means of pins 26.
The other ends of the arms 24 are pivotally attached at 28 to a bracket 30 which is rigidly attached by bolts 32 to a motor housing 34. The same bolts 32 fasten a thumb plate 35 to the housing 34. The housing internally supports an electrical motor (not shown) having an armature shaft 36 with an eccentrically positioned, headed drive pin extension 38 freely turnable in a hole in a rectangular upper plate 40. The upper plate is thereby supported on the shaft 36 and is driven eccentrically by it. The upper plate is restrained from rotation as a whole, while every point of its surface is caused to describe a circular path of the identical small diameter. It has been found that a diameter of about oneor two-tenths of an inch is successful, for example. The housing, motor and plate may be constructed in substantially the same manner as the corresponding parts of an orbital sanding machine of the type now in common use for furniture finishing and the like. A power cord 42 extends to an electrical outlet. An off-on switch 44 has connections extending from the housing 34, and is fastened to the backplate 20 and completes a circuit from the cord 42 to the motor.
The bracket 30 has two limit pins 46 projecting from it on each side in position to limit the pivotal movement of the arms 24 relative to the housing 34. As shown in FIG. I, the pins are located so as to insure a sufficient wide opening for easy insertion of the overlapped ends of fiber bundles 48 and 50 to be spliced when the thumb plate 35 is depressed. As shown in FIG. 2, the pins are also located so as to permit self-leveling of the upper plate 40 on the baseplate 18 when the thumb plate is released.
The base and upper plates are preferably both covered with sheets of sandpaper 52 and 54, respectively (FIG. 3), either clamped by conventional means or adhesively attached to their respective surfaces. Sandpaper of 60 grit has been found satisfactory. In the alternative other coverings may be employed, such as card clothing, felt pads, rubber or plastic material, leather, steel or combinations of the foregoing or similar materials, with flat surfaces or with ridged or otherwise textured surfaces.
In operation, the machine is carried to the location where a splice is required, the thumb plate 35 is depressed to move the parts to the open position shown in FIG. 1, the overlapped, parallel fiber bundles 48 and 50 are manually inserted in the position shown with the overlapping region entirely within the machine as shown in FIG. 3, and the machine is closed to the position shown in FIG. 2. In this position, the pressure of the upper plate is brought to bear directly upon the overlapped fiber bundles and is produced by the weight of the pivoted parts, principally including the housing 34 and the motor. By the use of auxiliary springs (not shown) this gravitational pressure may be either augmented or diminished in order to produce the optimum net pressure to hold the fibers close together while the machine is operating.
Next, the motor switch 44 is turned on, causing the upper plate 40 to oscillate at a substantial rate, thereby shaking or rubbing the fibers together. In normal use, the machine is left on for a few seconds only, after which it is shut off and opened to remove the completed splice 56 (FIG. 2). The splice has sufficient strength for the purpose indicated above as a result of the fact that a component of the oscillation, produced in the fibers by their frictional engagement with the upper and baseplates, is normal to their direction of extent, in addition to being normal to the direction of applied pressure.
It has been noted that various factors have an influence on the character and strength of the splice obtained. One of these is the speed of oscillation. Experiments were conducted on machines ranging in speed from 4,200 rpm. to 9,000 r.p.m. with good results. In general, slower speeds resulted in an increase in the time of operation required for an acceptable splice. The machines used in successful tests had diameters of oscillation ranging from about 0. 109 inch to about 0.181 inch.
A further influence on the time required for splicing is the grade of the fiber bundles being spliced. In general, woolen card slivers required more time than strands of wool top, and the finer diameter grades of wool required less time. As typical examples, for a 66's grade wool and using a 4,200-r.p.m. machine, top required about 5 seconds as against about seconds for a card sliver. For 80s grade wool, top required about 2 seconds and for 50s grade wool, top required about seconds.
The pressure on the fibers is also a factor as noted above. It should be sufficient to hold the fibers in intimate contact but not so great as to interfere with vigorous partially random fiber agitation laterally to their direction of extent.
The extent of the overlap of the fiber bundles has a bearing on the strength of the splice when the overlap is small. For example, the strength of a typical splice increases substantially with increasing overlap of wool slivers, up to about 3 inches. Above this figure, increasing overlap does not significantly increase strength and is therefore usually unnecessary.
The moisture content of the fibers has also been shown to influence the strength of the splice and the time required to make it. This is particularly true in the case of wool, with which it has been shown that fibers with about 15 percent moisture content will splice substantially more readily than fibers with about 5 percent moisture content. To increase the moisture content, a variety of means may be readily employed. These means may be integral with or fastened to the machine of FIGS. 1 and 2, or they may be entirely separate. They include, for example, various dispensers for water in the form of drops, spray, vapor or steam jets, such as those used on domestic steam irons, and such means may be fitted with dials to control the dispensers as a function of the grade of wool being processed. The moisture may impinge directly on the fibers in the overlapped region when the device is open as in FIG. 1, or it may reach the fibers when the device is in closed position through suitable holes in the opposing plates.
In a similar manner, provision may be made to introduce heat to produce an optimum condition for forming the splices.
Various modifications may be made in the foregoing apparatus, if desired. For example, while a circular orbital or two-dimensional type of motion is used in this embodiment, a straight reciprocal or one-dimensional motion may also be employed, in which case the dimension in which the motion occurs lies transverse or normal to the direction of extent of the fibers. Also, while only the upper plate reciprocates in this embodiment, both plates may be made to reciprocate but in opposite directions or out of phase with one another. Further, the surfaces of the plates may be congruently curved.
While the device shown is electrically driven, other kinds of power may be employed in the alternative. For example, compressed air or hydraulics may be used to drive the motor, this form of power being readily available in or near the processing machines in present use.
The foregoing machine and process may be used to splice such diverse fibers as wool and synthetics, including Dacron, nylon, rayon, polypropylenes and polyesters of the type used in yarns.
