This invention is for improvements in and relating to yarn bobbins, cones, spools and the like. In winding yarn packages on to a cone or other centre, it not infrequently occurs that the 5 ends of two lengths of yarn have to be knotted together. In the case of comparatively soft yarn or threads, it is possible to continue winding in the ordinary manner after a knot has been 7 formed, with the result that the knot is wound into the body of the package. This is not practicable, however, in the case of hard yarns or threads such as natural silk in the gum or artificial silk (which for knitting are usually wound in frustro-conical packages) for reason that when the thread is subsequently being unwound, as for example in machine knitting, it catches beneath the knots and is out or broken.

An object of the present invention is therefore to provide a yarn package of the type from which the yarn or thread, particularly hard thread, is adapted to be drawn off endwise, in which knots or other irregularities in the thread are so disposed as not to catch the thread that is being withdrawn.

With this object in view this invention, as viewed from one aspect, provides a method of winding packages of yarn, particularly hard yarn such as natural silk in the gum or artificial silk, which consists in so winding the yarn on to a centre (e. g. a cone or tube) that any knots present in the yarn are brought on to or over an end face of the centre and lie thereon at a less radius than the minimum radius of the yarn windings. Hence, during unwinding the yarn may be drawn freely off the package without catching the knots. More specifically, there is utilized in this method a centre having its diameter abruptly stepped downwards near one end (the small end in the case of a cone) to provide a flange or shoulder and any knots present in the yarn are brought on to the said shoulder.

The invention also includes a yarn package wound on to a centre, e. g. a cone or barrel tube,

having an inwardly directed flange at or near the drawing-off and on to which flange the knots, if any, in the yarn are brought.

In order that the invention may be better understood, reference will now be made to the accompanying drawings in which Figure 1 is a perspective view of a silk cone according to this invention.

Figure 2 is a perspective view of a cylindrical yarn package according to this invention.

Figure 3 is a plan view of a package such as is shown in Figure 1 or Figure 2.

Figure 4 is a perspective view of a conical centre according to this invention, while Figure 5 is a section therethrough.

Throughout this description, like reference numerals indicate like parts.

In the exercise of this invention, a silk or other thread is wound in the form of a package l0, having an exposed end face H (which in the case of a frustro-conical package or cone as shown in Figure 1, may be a small end face so that it is possible to withdraw the yarn endwise), upon the exterior periphery of an elongated central body IZ. This body has an end face [2a which extends inward from the threadreceiving exterior. In the operation of winding the thread upon the said exterior, between the end face H211 and the other end of the centre, when a knot or other irregularity it in the thread is reached, the winding operation is temporarily interrupted and the length containing said irregularity is laid across the end face 120. so that the knot I3 is exposed thereon at a radius less than the minimum radius of the yarn windings at that end of the package. Therefore, the knot is so disposed that it will not interfere with the withdrawal of the yarn from that end.

It is preferred to form the inwardly directed end face I211 as a shoulder near one end of the central body. Such a shoulder may be formed either upon a conical body as is shown in Figures 1, 4 and 5, or upon a parallel body H2 as is shown in Figure 2, according to the type of package.

The central body may be made of compressed paper (preferably having a varnished face) wood, metal, or of any other substance commonly utilized for such an article. In the case of a cone, instead of being uniformly tapered down to its small end hi, it is stepped near said end as shown in Figures 4 and 5. By virtue of this step, a narrow inwardly directed flange or ledge lZa is provided from the centre of which the end portion of the cone projects. This end portion may be of open frustro-conical formation or it may terminate in a substantially hemispherical top pierced with a central hole.

Such a cone centre may be either formed in one piece or the ledge l2a may be produced by attaching a separate top piece. In the example shown in Figure 5, the cone consists of a frustroconical body indicated by the number I2b having inserted into it a further conical body H20 which projects from. the small end thereof. In this manner, a ledge |2a equal to the thickness of the peripheral walls of the body l2b is produced.

I claim:-

1. A method of winding packages of yarn, par-- ticularly hard yarn such as natural silk in the gum or artificial silk, which consists in winding the yarn onto a centre having an end face and bringing any knots present in the yarn onto or over said end face so that they lie thereon at a less radius than the minimum radius of the yarn windings.

2. In producing wound packages of yarns of the kind adapted to have the yarn drawn off them endwise of the package, the step of locating such knots as are present in the yarn at an end face of the package and at a radius less than the least radius of the yarn windings at that end.

3. In winding onto a centre a yarn having a knot in it, to produce a wound package from which the said yarn is to be drawn off endwise, the step of bringing said knot to the face of the drawing-off end of the package and positioning it at a radius less than the minimum radius of the package coils at that end.

4. In producing a wound package of silk, from a thread orvyarn having a knot or knop therein, by winding onto a centre, the steps of interrupting the winding at the knot or knop and passing the length of thread containing it across the end face of the package so that the said knot or knop is exposed at said face at a radius less than the package windings.

5. A method of producing a wound package of yarn which comprises employing a centre having its diameter abruptly stepped downwards or reduced near one end thereby to provide a flange or shoulder, winding the yarn onto said centre between the flange. and the other end, but passing any knot or knots present in the yarn across the face of said flange.

6. A method of producing a wound package from yarn having at least one cross-sectional irregularity therein, which comprises taking a centre-body of elongated form, winding the yarn thereon in a package having an exposed end face, and during the winding laying that portion of the yarn, in which the irregularity occurs, transversely of the end face with the said irregularity at a radius less than the minimum radius of the package windings at that face.

7. A method of producing a wound package from yarn, an intermediate length of which includes an irregularity, which package includes a central elongated body having an end face directed inwards from a yarn-receiving exterior, which method comprises winding the yarn onto said exterior in the form of a package having an end face, adjacent said inwardly directed end face, exposed, and disposing the said irregularity on the said inwardly directed end face.

8. A wound package of yarn comprising an elongated central body having a yarn-receiving exterior and at one end an end face directed inwards from said exterior, yarn wound around said exterior in the form of a package having an end face, adjacent said inwardly directed face, exposed, and a portion of the yarn containing an irregularity extending across the said inwardly directed end face between successive coils of the winding.

9. A wound package of yarn comprising a centre with the yarn wound thereon, and having in the yarn a knot which is exposed at an end face at a radius less than the least radius of the windings at that end.

10. A wound yarn-package of the kind adapted to have the yarn drawn oif it endwise, which yarn contains a knot, comprising a centre having an end face adjacent the drawing-off end of the package on which centre the yarn is wound between said end-face and the. other end of the centre, with the knot upon said end face.

11. A wound package of yarn having one end face of the yarn windings exposed, comprising a centre surrounded by the wound-on yarn, in which yarn there is a knot that is exposed at said end face at a radius less than the minimum radius of the package windings thereat.

12. A wound package of yarn having the end face of the yarn windings exposed, comprising a centre surrounded by the wound-on yarn which centre is abruptly stepped down in diameter near one end thereby forming a shoulder, which shoulder is exposed at the said end face and having a crosssectional irregularity occurring in the yarn between successive windings thereof laid across and exposed on the face of said shoulder.

13. A frustro-conical package of wound yarn having the small end face of the yarn windings exposed, comprising a tapered centre having an inwardly directed peripheral step near one end, which centre is surrounded with theyarn windings between said step and the other end, and

having a portion of the yarn in which an irregularity is present extending across the face of said step. 7
