The present invention has for its object the provision of a novel and improved Winding machine for winding packages of yarn or thread which by the interchange of a few simple parts can be adapted for winding an unusually large variety of packages. A further object of the invention is the provision of a winding machine which is durable in construction, and involves no complex mechanical motions for controlling and varying the traverse of the thread across the rotating package. Still another object of the invention is the provision of a winding attachment which can be easily adapted to existing types of winding machines so as to increase the variety of packages which they are capable of winding.

The invention also provides a winding machine in which the fast moving parts are of light construction which are subjected to little wear and the nature of the package produced is determined by the shape of the thread guiding surfaces. The invention further provides an improved winding machine for Winding thread onto a rotating core of cylindricalor tapered shape in helical coils of any desired, constant or varying pitch to form self-supporting packages and in which the thread is guided by being passed over or. through a plurality of slots or elongated thread guiding surfaces which are relatively movable and have their slots or other thread guiding surfaces intersecting so that their relative movement accurately and positively controls the position of the thread along the rotating package. In accordance with the illustrative embodiment of the invention which is shown as applied to a winding machine for winding packages supported on and rotated about a fixed axis, means are provided for rotating the cylindrical r conical core at a relatively high speed and the traverse of the thread or yarn along the rotating core is controlled by a plurality of thread guiding members, one of which generally moves back and forth along the package while another is either fixed with reference to the surface of the package or may be angularly moved about an axis substantially normal to that surface. One of the thread guiding members is preferably in contact with the surface of the package and is mounted on a swinging frame so that it may move away from the cor axis and yet remain in contact with the surface of the package as the package builds during the windin operation, and it may also be provided with means for equalizing its pressure against the package surface so that its pressure is uniformly distributed over the package.

The thread guiding member in contact with the package surface is preferably provided with an elongated thread guiding surface which may be in the form of a slot and this surface may be straight, curvilinear, angular, continuous or in: terrupted and may be held in a fixed position with reference to the rotating package surface or it may be mounted so that its thread guiding surface is movable angularly with reference to the package axis and surface.

, The cooperating thread guiding member generally comprise a slotted member moving back and forth across the surface of the package, its speed of reciprocation or oscillation relative to the rotation of the package spindle being determined by the numberof coils of thread which are to form one of the hellcal'layers of the package. The thread guiding surface or slot of this member may also be straight, angular or curvilinear and is preferably so positioned relative to the first thread guiding member that the two thread guiding slots or surfaces lie closely adjacent to each other with their slots superposed and at arelatively great angle.

As the two cooperating thread guiding members and their surfaces or slots are relatively moved the point of crossing of these surfaces or slots changes, and as the thread passes through both slots or over both surfaces under some tension, its position along the surface of the package being wound is determined by and corresponds to this point of crossing thereby causing the thread to be traversed alon the package. The traverse of the thread may, obviously, be varied either by changing the relative position of the slots or by a combination of such changes. In this way a very precise control may be had of even a complex wind solely by varying the shape of the relatively movable thread guiding means, and a wide variety of packages such as can be produced otherwise only by an equally wide variety of machines can be produced by a single machine and a relatively few interchangeable parts.

It will be understood that the foregoing general description and the following detailed description as well are exemplary and explanatory of the invention but are not restrictive thereof.

Referring now in detail to the illustrative embodiment of the invention as shown in Figures 1 to 5 and 13 to 15 of the drawings, the invention is applied to a winding machine adapted to wind thread or other strand material onto a core from any desired supply through thread tensioning devices and under control of thread guiding means. A main stationary housing 6 supports the rotatable driving spindle 2 and a rotatable shaft 3 upon which is fastened the main traverse cam l connected to reciprocate the thread guide 5 carried by a guideway frame 5 which is mounted in the usual manner for swinging about the shaft 3, against the tension of a spring 8. A second thread guiding plate I, is provided between theguide 5 and the surface of the package being wound on spindle 2.

Thread guide 5 is connected for reciprocation by the main traverse cam tthrough the traverse tube 9 which is sli-dably mounted on the guide rod l0 carried on the swinging frame 6. At one end tube 9 carries a cam follower H which runs in the cam groove l2, while at its other end it is connected to the bracket is which supports the thread guide 5, this thread guide being held in a fixed vertical position by means of the guideway members it and i5 so that it reciprocates in close proximity to the package surface engaging thread guiding plate 7;

Thread guiding means 5 is formed with a thread guiding slot to, which is more or less vertical, and plate l" is formed with a thread guiding slot la which is more or less horizontal, these slots crossing each other in all their positions.

Means are provided for varying the angular position of the slot in the plate 7 as the package increases in size during the winding operation and for this purpose a bracket It supports a short stud it upon which is rotatably mounted a double grooved pulley 2i bracket l8 being mounted on the guideway framed, and bracket 2i supporting oneend each of the flexible steel bands 22a and 22b respectively fastened to the spindle bearing housing 23, the other ends of the steel bands 22a and 22?) being wrapped around and fastened in the grooves 20a and 20b of the pulley 2|], As the pulley 20 is moved bodily in one direction by swinging of the frame 6, as the package builds, it rolls along the flexible bands 22a and 22b, unwinding one band from the surface of the pulley as the other band is Wound on the pulley, thereby rotating the pulley 22 and its arm 24 which is linked to an end of pivoted plate I by means of link 25. A lever 24 provided with a series of holes 24 is fastened to one side of the grooved pulley 20, and link 25 is connected at one of its ends to one end of the thread guide plate I, while its other end is pivotally mounted in one of the lever holes 24. On the other side of the pulley 2|) is mounted another lever 21 near the end of which is adjustably mounted a counterweight 28a, shown in detail in Figures 15a, 15b, 150 to overcome the effect of the swinging frame balancing spring 8, thereby counteracting the effect of the spring 8 on the pressure between the guide plate I and the package.

As illustratively shown in Figures 1 to 5, the thread guiding plate I is pivotally mounted to incline the thread guideway by means of a pivot stud I33 which projects from an adjustable bar 31 said bar being adjustably fastened to the yoke 3| by screws 38 and 38' and said yoke 3| being fastened to the plate I near its ends. The pivot stud I36 is mounted in a cradle bearing I38 from which extends the vertical pivot stud I32 which is supported in the split bearing |3| of the bracket I33, said bracket I30 being adjustably secured to the inner face of the bar 33 extending the length of the guideway and secured in suitable alined position by means of the supports 35 and 35' mounted on studs 34 and 34 projecting upwardly from the guideway frame 6. Yoke 3| is spaced from plate I for most of its length so as to provide a narrow parallel-sided slot in which the thread guide may reciprocate. Between the ends of yoke 3| and bar 33 are provided series of holes for screws 38 and 38 and 54 and 54 respectively. The adjustable bar 31 and the bracket I36 are provided with slots for longitudinal adjustment, thus the adjustable bar 31 is adjustably fastened to yoke 3| by means of screws 38 and 38 and the bracket I30 is adjustably fastened to bar '33 by means of screws 54 and 54 so that the longitudinal positions of the axes of pivot studs I32 and I36 may be varied to accommodate the winding of different lengths of packages and permit the pivots I32 and I36 to be positioned substantially centrally of the package being wound, also to permit the pivots I32 and I36 to be positioned either side of the central position of a package being wound.

An advantage of providing means to pivot the guide plate I either side of a relatively central position is that it is possible to use a single slanting reciprocatingguide such as 5 with an adjustably longitudinally positioned horizontal pivot which provides for the plate I to swing with one end, such as the nose end, in a relatively lesser radius and are and the other end, such as the base end, in a relatively greater radius and are for thepurpose of producing a package with less taper at one end such as the nose and more taper at-the other end such as the base.

By comparing the two settings, it should be noted that with a relatively central position of the horizontal pivot and a single slanting traverse guide, a package is built up with the same taper in each end, and with a position of the horizontal pivot nearer the nose, a package is built with less taper at the nose and more taper at the base and using the same single slanting traverse guide in both instances.

Guide plate I is connected with the means for angularly shifting its position by means of the link 25 which is pivotally connected to a pivoted stud 4| projecting from one of the holes 24 in the lever arm 24 connected to the double pulley 20, while the other end of the link 25 is pivotally connected to a short stud 43 projecting from and pivotally mounted on the end of the guide plate I, so that the angular position of the guideway is controlled in all its positions by the position of the swinging frame 6 through the steel bands 22a and 22b, pulley 20 and the associated parts.

Means are also provided for steadying the plate I so that it tilts in a plane which is fixed with reference to the swinging frame 6 and for this purpose an arcuate guideway I28 is formed with a curved slot I2I which fits over an end of the guide plate I, the radius of curvature of the slot corresponding to the radius of the plate I, and this guideway I28 is securely supported on the swinging frame and fixed thereto by means of the support 35 so that it is beyond the nose of the package and does not interfere therewith.

Thus the guide plate I is tangent to the surface of the package and is pivotally mounted about an axis normal to the tangent plane so that it may be tilted to vary the traverse of the thread on the packages as the thread is moved a constant distance by the thread guide 5, thereby varying the shape of the package wound.

Figures 1 and 2 show the arrangement of the parts at the beginning of winding of a tapered end package such as is shown in Figure 21. Figure 3 shows the parts more in detail, the slot in guide plate I being in its initial horizontal position, while the thread guide 5 is shown in its two extreme positions of reciprocation, the full line position being the right hand end of its traverse While the dotted line showing of thread guide 5 shows the thread guide at its extreme left hand position. It will be noticed that the movement of the thread guiding slot 5a along the horizontal guide plate slot Ia (which is longer than the package to be wound) is equal to the movement of the thread guide 5 as measured along the traverse rod I0.

Figures 4 and 5 show the positions of the parts when the winding of the tapered end package has been completed and the traverse of the thread along the package is considerably shorter than the traverse of the thread guide 5. It will be noticed in these figures that the swinging frame 6 has been moved to the right (Figure 5), guide plate I is still tangent to the surface of the package, the steel bands 22a and 2211 have caused rotation of the double grooved pulley 20 to cause a rotation of the guide plate tilting lever' arm 24 which has caused a corresponding clockwise (Figure 4) tilting of the guide plate I about its pivot I36 so that the guide slot Ia is now inclined at a considerable angle with respect to the axis of the package. The extreme positions of reciprocation of the thread guide 5 are shown in Figure 4 and it will be seen that the distance between the extreme positions of the intersection of the thread guide slot 5a with the guide plate slot la is considerably less than the distance between the extreme positions of the thread guide 5, and that this shortening has taken place at
