WIN DING CORDAGE.

Application led August 9, 1924. Serial No. 731,076.

To all whom t may concern.'

Be it known that l, HENRY A. BoDWELL,

a citizen of the United States of America,

and resident of Andover, in the county of Essex and State of. Massachusetts, have invented newand useful Improvements in Winding Cordage, of which the following is a specification.

This invention relates to winding cordage andto a Wound mass or package of cordage adapted to be evenly unwound from its interior layers outwardly.

In a preferred form the cordage package or mass may be of any cross-wound type, such as a/ball, cheese or cop characterized by self-sustaining structure comprised of the cordage itself. The cordage referred to 1n this specification comprises any filament or association of filaments whatever such as, for example only, spun, laid, twisted or braided yarns, cords or twines, sewing threads, rope, Wire or wire-rope, strips, tapes or braids.

The well-known forms of packages made by winding with quick-pitch axial or surface traverses on a cylindrical or conical support, producing a ball, cheese or cop having the so-called Fiji, lVardwell or Universal wind, is convenient for most uses, comprising a self-sustaining mass in which each layer of accretions of the winding cordage consists of many runs of the cordage extending` in the axial direction from one end to the other end of the package, which is cylindrical or frusto-conical, the ends transverse to the axis being comprised of the cusps at reversals of the runs of the component spiral elements severally building up into each layer. When interiorly supported by a headless tube, cone or quill, as in usual practice, such yarn packages are of ancient and approved use, having the quality of evenly unwinding from their exterior end or side faces without weakening the structure of the remainder of the winding.

But there are many situations in which it is advantageous to provide for unwinding cordage of the kind referred to from the interior outward; for example, for the purpose of preventing tangling or ballooning,

or in order to'pe'rmit the cordage packages to be unwound from cells or containers little or no larger than the wound package without substantial variation of tension from part' to part of the unwinding operation; or to provide for unwinding several balls or masses dem from within the same container. ball or package capable of unwinding from withiny which shall also have the structural and other advantages of the quick-traverse cross-Wound structure is thus highly desirable. The ordinary traverse, cross, or Fiji-wound package when its core, tube or quill is withdrawn to permit unwinding from within is not suitable forthese purposes because its structure is such as then to permit the whole wound mass to be broken across, or to be extended lengthwise joined together in tan- 1 witl` loss of compact solidity, respectively by y breaking stresses acting orosswise of'the axis of wind, or tensile stresses acting along the axis. These qualities of the Wound packages prevent their commercial use effectually, too large a proportion of such unsupported packages being so deformed before use, in making or in shipment, as to prevent unwinding from Within with the necessary regularity and freedom from snai-ls. In large fields of use, such as for twine packages for wrapping or bundling, and particularly for the harvester binders, there is little or no use of this described type of package for the mentioned reasons. j

This invention therefore has among its objects to provide a cordage package or wound mass for interior unwinding free from these disabilities at no substantial increase of cost, as well as an art of making this article of manufacture and apparatus for practicing the method or art.

The invention will be explained in connection with one exempliflcation only of the article, method and apparatus as shown in the accompanying drawing, in which;

Fig. l is a transverse section through the center of a cordage package embodying the present invention;

Fig. 2 is an elevation of broken away supply of twine for v applied reinforcement may ,Fi/g. 3 is a front elevation of a suitable old Winding machine showing simple apparatus for carrying out this method;

Fig. 4. is a side elevat-ion of a feeding guide; and

Fig. 5 is a detail transverse section on the line 5-5 of Fig. 4.

The cordage package A, Figs. land 2, may be made up of a plurality of cross- Wound or Fiji-laid layers of relatively steep angular pitch, the spiral runs being reversed at the ends of the layers as usual, as at r, Fig. 2. In the form shown cusps or reversals r of the layers appear at the end surfaces of a cylindrical i package, the yarn concerned coming to View presently at the other end of the package. Thus a relatively rigid, Self-sustaining package may be made from which'the yarn is unwound from the inner or central layers. The cordage packagey may have any desirable relation of length to diameter, and may be conical, ovoid or spherical, if desired, but in any form is characterized by layers of windings of relatively7 quick-pitched traverses.

Machines for winding yarn for making such cordage masses are well known, a machine for this purpose of one of the types in large vpresentuse being indicated in broken lilies in Fig. 3. Such machines ordinarily include a winding spindle 1 upon which the yarn is wound as laid by the. traverse guide 2 for the spiral or cross layers, the cam 3, for example, reciprocating the traverse guide 2 perpendicular to the plane of Fig. 3 in relation to the rotation of spindle 3.

It will be understood that the spindle 1 is adapted to provide a temporary support during winding only, the wound package being removed when complete. Instead of providing an interior tube or cone to support the dotted package, it is herein provided that the package shall contain one or more flexible reinforcing inclusions held in place by being caught between adjacent layers of the cordage. Preferably these inclusions are nearly but not quite coextensive with the axial length of the package, only a iew thousandths of an inch in thickness, and circumferentially discontinuous, so that when uncovered upon unwinding, the reinforcing inclusions are left free and will not disturb further unwinding. For these purposes a suitably shaped sheet of thin, tough and flexible paper is preferred as shown at B. These should be of such a width as to nearly cover the axial Width of a cordage layer, and such length as nearly to cover the circumferences of the winding cylindrical mass when applied to layers near the exterior of the winding mass. For a cylindrical package, the sheets of paper at B are preferably rectangular. As shown at b the lirstoverlap on being wrapped about the forming winding.

mied through the guide by hand orl gravity comes into contact with the surface of the package at the nip or place of contact of the winding run of cordage and the previously laid surface. The guide '4 may be suitably supported so that its lower e'nd lies in such relation to any surface concentricv with spindle l as to accomplish this. For

example, a guide 4 of suitable length is pivoted at 7 on any suitable attachment to the winding machine, such as a member of a frame bearing a horizontal member 5 and an upright 6. The lower end of guide 4 thus rests on the winding surface and moves on an arc passsing near the axis of spindle l, and clearing the locus of motion of traverse guide 2. The leading edges of the inclusions, layers or sheets of material B drop into the nip between guide 2 and the winding surface, to be caught and held by the cordage t as the rotation of the winding mass draws the paper or other inclusion B from the guide 4. Sheets B may be fed to the forming cordage mass at intervals of a predetermined number of revolutions of the winding spindle if desired, so that they may be accordingly spaced in the finished package to provide resistance to tensile strains. Sheet Jfeeding devices of any desired type may be used for feeding the sheets B to the guide 4, but manual feeding is ei'ective for the purpose.

A cordage mass or package provided with the layer or layers B is not subject to the objections inherent in cross-wound packages. Such a reinforced package effectively resists all breaking or tensile strains tending to distort it from' its original condition, and is capable of unwinding uninterruptedly, the discontinuous flexible sheets B going free without snarling the unwinding run ot cordage when unlocked by unwinding.

It will be observed that the circumferential discontinuity of the inclusions B is useful to permit the cordage of a layer, as at b2, Fig. 2, to pass above and exterior to the reinforcement at any axial position of the winding run of cordage at the time when the edge of the inclusion B maybe placed on the winding mass. l

, Since the packages are intended for inside unwinding, it is desirable to prepare the outer layer to resist slackening. For

i uo

this urpose the end of the yarn or twine or ot er cordage may be tucked under a previous run, as usual, at m, and the reversal cusps of the last few yarns laid' are preferablly fastened down. A preferred way of doing this is to provide, as indicat- .ed by the shaded area lw a stiffening of some adhering and penetrating substance Alof a harmless nature adapted also to stick together the adjacent runs of the cordage. ,A dab of hot wax or paraffin applied with a brush at the two points at each end of the package is preferred and recommended for this purpose.
