OF AUBURN, NEW YORK, A CORPORATION OF NEW YORK APPARATUS FOR MAKING 'ooM mEn PAPER AND FIBER CORDAGE Application filed July 30,

This invention relates to improvements in cordage or rope structures and more especially, though not exclusively, to paper twine, that is, twine made up of a combination of paper and fiber. The'invention also relates to the method and apparatus for making such cordage. While'the inventions relate particularly to paper twine they are also applicable to other rope structures, including cable-laid ropes.

It has heretofore been proposed to produce twines of this general type having a fiber center covered with paper, but in practically all instances there has been imparted to the covering of paper a twist or creasing and the primary ob ect of the present invention is to produce a paper wrapped twine or piece of cordage in which the paper and fibrous elements are not .twisted together but in which the paper, in the form of a strip, is wrapped spirally around the fiber elements, the several convolutions of paper thus formed being substantiall fiat but having their adjacent edges over a'pping so as to completely and entirely cover the fibers.

In the accompanying drawings,

a paper covering to rope.composed of three drawn on to the exterior of the body of fibrous elements in such fashion as to be laid thereon in; substantially flat, spirally arran ed overlapping convolutions. The mec anism employed consists of means for feeding the fibrous elements to the twisting mechanism, and means for supporting and guiding the paper stripon to the exterior surface of such elements as the latter are being twisted, such paper supporting and guiding means being so arranged with respect to the longitudinal center of the fibrous elements that the paper will be wrapped, Without twisting, crimping or folding around the twisted fibrous elements so as to entirely cover the latter.

The mechanism may, of course, be varied in some of its details from the structures shown in the accompanying drawings, but it is essential in both the apparatus as well as in the method, that the paper be applied ing the paper, or without effecting a twisting together of the fibrous elements and paper strip. Further by applying the paper at the time said elements are being twisted, the twisting motion serves to feed the paper.

From a commercial standpoint, it is more convenient and more economical to employ the apparatus shown in the accompanying drawings. .Referring to Figs. 1 to 5 the fibrous elements which, in this instance are slivers to be assembled or twisted to form a yarn, are fed by the pins 10 on the bars 11 of the ordinary rope making machinery to and through the fiber nipper 12 which may be of substantially any construction now found in common use. From the nipper 12 the slivers pass to a second nipper 13 from whence they pass, in the form of the finished product, to the bobbin 14. In accordance with usual practice it will be understood that as the fibers pass from the nippers 12 they are operated upon by suitable mechanism which functions to twist them together. In fact all of the mechanism, except that for applying the paper strip to the twine, may be constructed and arranged in accordance with well known practices of the art today.

In the present instance, however, suitable means are provided for applying a covering of paper in the form of a continuous strip to the fibers forming the twine. This mechanism may take various forms, but in order to facilitate the application of the paper to the cordage being made it is preferred that said paper he applied at the time the fibers are being twisted together, whereby the twisting motion of the fibers will tend to feed the paper on to the twine. With this object in view the paper is preferably applied to the yarn between the nipper 12 and nipper 13, preferably at a point 'just in front of nipper 13.

This paper applying mechanismpreferably comprises a suitable source of supply such as the roll of paper 15 carried in a bracket 16 on the frame of the machine from which the paper passes over a roller 17 journaled in a receptacle 18 on a bracket 19 in such fashion that the lower portion of said roller will be submerged in a liquid whereby the paper passing over the roller will be dampened to facilitate its conforming to the contour of the cordage being produced. From the roller 17 the strip of paper passes successively over frusto-conical rollers 20-21 suitably mounted in brackets on the framing machine, these rollers being so arranged as to guide the paper on to the twisting fibers at such an angle to the longitudinal center of the cordage being produced that said strip in being wound on the cordage will be laid thereon in a series of spirally arranged convolutions 22, the juxtaposed edges of the convolutions overlapping one another so as to completely and entirely cover the cordage or twine. I

-By applying the paper strip to the cordage in this manner said strip, while spirally arranged on the cordage, is not twisted about its longitudinal center, so to speak. On the other hand, the paper is substantially flat at any point throughout its length. This 1s preferred to having the paper creased or folded, or twisted, in any manner, because with the paper substantially flat it has been found that the cordage is much more flexible and elastic thereby possessing stretching facilities.

As has been stated, the greater portion of the machine may be of the usual construction found on the market today and it is deemed necessary to go into a detailed description of such parts of the machine.

Further, it will be apparent that one or more layers of paper may be applied to the cord-- age and, also, the application of such strip or strips of paper may be accomplished by mechanism different from the specific arrangement shown in the present instance. The point of primary importance is to lay the paper around the rope without twisting, creasing or folding the strip.

In Figs. 6.and 7 there is illustrated the-- mechanism for appl ing the paper covering to yarns being ma e up of a plurality of twines. In this arrangement the twines are fed from bobbins 3O from which they pass through eye-plates 31 and thence to the nippers 12 and 13 at which point they are twisted together. From the nipper 13 the finished yarn passes to the bobbin 14. As in the case of the machine shown in Figs. 1 to 5 the paper strip in the form of a roll 15 is supported in the bracket 16 on the main frame of the machineand the paper in said roll passes over the dampening roller 17 and thence to the 'frusto-conical rollers 20 -21 which guide it on to the twisting twines at a point intermediate the nippers 12 and 13.

In the rope-laying machine shown in Fig. 9 the rope strands 40" are supplied from the reels 41 from which they pass through the layer frame 42 and thence to and through the guide block 43 which guides said strands to the ropenipper 12. Beyond the rope nipper 12 there is the paper-nipper 13 and at a point slightly in advance of said nipper 13* the strip of paper is guided on to the twisting rope by the frusto-conical rollers 20 21 this strip of paper being supplied from the roll 15 journaled in a suitable bracket 16 on the frame which roll the paper passes over the moistening roller- 17 between the supply roller 15 and the frustoconical guide roller 20 In each of the three instances illustrated it will be seen that paper is laid on the finished product in spirally arranged con volutions that are substantiall uncreased transversely of the strip. T is is true whether the cordage consists simply of a multiplicity of fibers twisted together, or

whether it is a plurality of elements formed of twisted slivers. In each instance the substantially flat paper will not detract from the flexibility or elasticity of the finished product so that the latter possesses greater combination of means for supplying a plurality of fiber elements, means for twisting said elements together to form the body portion of the cordage structure, a support for a continuous strip of paper, and means for maintaining said strip of paper substantially flat and guiding it from said support to the exterior surfaceof the fibrous elements as the latter are being twisted together, said guiding means comprising tapered conical rolls so located with respect to the twisting fibrous elements as to lay the strip of paper on to said elements in a series of substantially flat spirally arranged convolutions.

2. I combination of means, including a nipper,

for feeding and twisting a plurality of unspun fibers together to form a unitary core for the twine, and means for feeding a flat strip of paper to the fibers as they are being twisted together but after they have passed through said nipper, the rotation of the fibers while being twisted drawing the paper thereon whereby said strip of paper will be wound around the twisted fibers in a series of substantially flat spirally arranged convolutions.

3. In a machine for making twine, the combination of means, including a nipper, for feeding and twistin a plurality of unspun fibers together to form a unitary core for the twine, and means for feeding and wrapping a strip of paper on the fibers after they have passed through said nipper, said paper being wrapped in a continuous series ofsubstantially flat convolutions spirally arranged on the surface of the fibers, the rotation of fibers while being twisted drawing the paper tape thereon.
