  • the invention relates to a precision yarn winding machine.
  • An example of a precision yarn winding machine is shown on page 348 Fig. 2 of the second edition of the American Cotton Handbook.
  • this type of machine there is a driven spindle which carries the yarn package whilst the yarn is guided by a device which moves to and fro along the outer surface of the yarn package in such a way that a cross wind package is produced.
  • the device which moves the yarn to and fro the so-called yarn guide, is mounted at the end of a rod, the traverse bar, which slides to and fro in a slot or the like in the swinging traverse frame.
  • This traverse frame must be capable of moving in order to make it possible for the yarn guide to continue to execute its movement in the immediate vicinity of the outer surface of the yarn package as the diameter of this yarn package grows.
  • the traverse frame is for this purpose capable of swinging around a shaft which is parallel, or practically parallel, to the spindle.
  • This shaft is driven together with the spindle and is capable of rotating in bearings in the frame of the machine as well as in the traverse frame, without causing rotation of the traverse frame.
  • This shaft carries a device, usually called a traverse-cam, but which in fact is a body possessing a slot situated on a cylindrical surface, this surface being concentrical with the shaft.
  • a projection of the traverse rod is situated in the slot of the traverse cam, whilst the slot is shaped in such a way that the rotating traverse cam causes this projection, the traverse rod and the yarn guide to move to and fro in the desired way in the traverse frame.
  • the type of winding is determined by a suitable choice of the relation between the rotational speed of the spindle and the rotational speed of the shaft carrying the traverse cam.
  • the position of the traverse frame is determined by the fact that the smooth and more or less spherical part of the yarn guide rests against the outer surface of the yarn package.
  • the traverse frame possesses a freely rotatable roller, the so-called roller bail, by means of which this traverse frame rests against the yarn package.
  • the invention relates to a new construction of such a precision winding machine.
  • the relative movement of the spindle carrying the yarn package and the frame in which the device determining the spot where the yarn is wound on the yarn package moves to and fro, this relative movement being necessary in order to allow for the growing diameter of this yarn package is a rectilinear translational motion.
  • the invention embodies various advantages, which will be discussed below.
  • the traverse frame should exert not more than a slight pressure on the yarn package, this pressure being either constant or varying according to a pre-determined function of the yarn package diameter.
  • the traverse frame in the usual machines the traverse frame must be perfectly balanced, and must moreover be provided with means to cause the desired pressure to be established.
  • a conical yarn package is to be wound, and the traverse frame is provided with a pressure roll by means of which it rests against the yarn package, then the entire length of this roll will rest against a gen'eratrix of the conical yarn package in one position of the traverse frame only.
  • the pressure roll Wlll rest against the yarn package, in theory only in one point, and in practice with only a small part of its length. The result of this is that the density of the package is not the same throughout this package. If the traverse frame is not provided with a pressure roll, the yarn guide will move along a generatrix of the yarn package in one posltion of the traverse frame only; in all other positions of this traverse frame the yarn guide describes trajectories which deviate from a generatrix, thus causing the pressure exerted by the yarn guide on the yarn package to vary; this is equally undesirable from the point of view of the formation of a package of constant density.
  • the density of the package is desirable for the density of the package to be constant throughout as inconstant density causes difiiculties in uniform dyeing in the case of package yarn dyeing, whilst, moveover, the forces necessary for unwinding the yarn package over the end will not be: constant, this causing trouble, especially in knitting machines.
  • the usual precision winders have the disadvantage that the forces exerted by the traverse cam on the traverse rod possess components, the directions of which are such, that they result in torques exerted on the traverse frame around the shaft of the traverse cam, these torques tending to move the traverse frame either towards the yarn package or away from this package. The said forces vary during each complete revolution of the traverse cam and thus cause varying forces to be exerted on the yarn package.
  • a winding machine When a precision winding machine is executed according to the invention, the balancing of the traverse frame is, as a rule, superfluous, as it is possible to cause this frame to execute its motion in a horizontal plane; the traverse cam cannot exert forces on the traverse frame, as a consequence of which the forces exerted on the yarn package by the traverse frame show less variation; a roller bail, if such a device is present, will continue to rest against a generatrix of the yarn package, independent of the diameter of this package, whilst the trajectory of a yarn guide resting 3 directly on the yarn package coincides "continuously with such a generatrix. Moreover, a winding machine according to the invention is capable of winding yarn package of various forms, especially of winding pine apple cones,

  • The'yarn to be wound passes to the yarn guide 103
  • An accidental advantage of the machine according to the invention is found in the'possi-' through the loop guide, a slub catcher and the tension device, which are not shown in the figure.
  • the yarn guide is mounted at the end of a traverse bar 105.
  • this slide carries two smallrollers .129, 204 one on its lower side and one on its upper side, these rollers being rotatable about vertical shafts.
  • the upper roller 129 is situated in a lower slot of the lever 120 (which has an H-shaped cross section'as shown in Figure 2a) and thus couples the slide to the lever.
  • the lower roller 204 is situated in the slot 122 of a cylindrical body 119 which serves as traverse cam. This body is mounted on, and driven by, the shaft 123, which shaft is driven by the spindle 117 by means of the gears 127.
  • the body 119 When the spindle 117 and the shaft 123 are rotating, the body 119 will, by means of the slot 122, move the slide 128 to and frobetween the g'uidebars 118. The slide will then drive the lever 120,; which consequently the traverse rod decreases as the traverse frame'is' moved farther from the spindle owing'to the'for'ces exerted by the yarn package building up.
  • The-rate of this decrease, and consequently the shape of the pine-apple cone are determined by the position of the fulcrum-112 of the lever 120. The nearer the fulcrum 112 19 situated to the spindle, the more acute will the conical surfaces 113 and of the yam package become.
  • The-ratio of the apexangles of these cones will, moreovenbe-influenced by a displacement of this fulcrum in a direction parallel to the spindle.
  • the fulcrum can be a fixedshaft
  • the position of the fulcrum 112 must be adjustable-.

  • roller bail 102 and of the spindle 1-17 are situated in one plane, this plane being parallel to the direction of displacement of the traverse frame 1 .11. Consequently the roller bail will be in contact with the yarn package along a generatrix of this package independent of the position of the traverse frame, and will be capable of executing the same pressure on all parts of this package.
  • balanc'-' ing can be effected in a simple way.
  • the traverse frame should be provided with a device of a well-known type permitting the traverse frame to move in the direction away from the spindle only.
  • a device of a well-known type permitting the traverse frame to move in the direction away from the spindle only.
  • the form of such a device is immaterial to the invention, and any good friction pawl is suitable for this purpose.
  • the forces on the traverse frame can be reduced still further by modification of the driving mechanism of the traverse bar.
  • This modification requires that either the one or the other of the two couplings of the type which permits a relative rotation and sliding motion of the parts coupled, i.e., the coupling between the said traverse bar 105 and the lever 120 or the coupling between the slide 128 and the lever 120, is replaced by a coupling of the type which permits only a relative rotation of the parts coupled, while the coupling between the lever 120 and the first frame 124 is replaced by a coupling which not only permits a relative rotation of these parts but at the same time permits a sliding motion of said lever along its fulcrum.
  • This latter coupling may be embodied in the manner illustrated in Figure 1A in which the lever 120 can slide along the shaft 112 owing to the fact that the lever 126 is provided with a slot 37 which is capable of sliding along the pin 112.
  • Another possible embodiment of this coupling is used in the machine shown in Figure 3, where the lever 120 slides in a small fork 348 which is rotatable about the pin 112 which projects from the bottom side of this fork.
  • the way in which the lever 120 is made to move to and fro is immaterial to the invention.
  • the method of driving shown in Fig. 1 is convenient, since it permits the application of the standard form of the traverse cam. It would also, however, be possible to drive the swinging lever by means of a normal cam disc, or a disc provided with a slot of suitable shape, driven, for instance, by a vertical shaft. It would also be possible to combine the driving mechanisms of the lever 120 of a number of winding machines situated vertically above each other. A similar combined driving of machines situated side by side would also be possible. It is a disadvantage of such a combined driving of the traverse movement, that either all spindles of the machines coupled in this way must be stopped simultaneously, or a special coupling device must be mounted, permitting the disconnection of such a lever from the combined driving mechanism.
  • the yarn package For certain applications it is desirable for the yarn package to possess a rounded shape. To form such a shape it is necessary that the decrease in the traverse length should be more than proportional to the displacement of the traverse frame. According to the invention this can be effected by means of a construction in which the traverse frame, whilst being shifted by the yarn package, displaces the fulcrum 112 of the lever 120. In this case a construction is preferably applied in which the swinging lever slides along the fulcrum 112, because then smaller forces are exerted on the traverse frame by the device causing the displacement of the fulcrum.
  • Part 101 is the traverse frame with the traverse bar 105 driven by the swinging lever 120, this lever being capable of sliding in a fork 348 rotatable around a shaft 112.
  • This shaft is carried. by a bell crank lever 343 mounted on a shaft 344, which shaft is rotatable in the frame of the winding machine.
  • the second arm of this bell crank lever carries a small roller 345, situated in a slot 346 of a plate 347 mounted on the traverse frame.
  • the position of the fulcrum 112 will not at first change.
  • the machine then winds the yarn package with normal conical ends.
  • the lever 343 will move the fulcrum 112 in the direction of the spindle.
  • the traverse length will then decrease at a rate which is higher than would be the case if it were influenced by the displacement of the traverse frame only.
  • the shape of the yarn package can be influenced in the first place by the shape of the slot 346.
  • the plate 347 is interchangeable.
  • fulcrum 112 at the end of the bell crank lever can be made adjustable, for instance by providing this end with a number of openings in which the fulcrum 112 can be fixed, whilst in addition it would be possible to make the position of the shaft 344 carrying the bell crank lever adjustable in the frame of the machine.
  • Fig. 3 shows only one method for automatically adjusting the fulcrum of the swinging lever 120. Other methods are, however, feasible. These methods need not result in a rounded shape of the yarn packages; many other shapes of yarn packages can be wound on machines with adjustable fulcrum of the swinging lever.
  • this slotted bar is perpen dicular to the direction of displacement of the traverse bar, then the two ends of the yarn package are conical surfaces, the generatrixes of which are perpendicular to the surface of the tube on which the package is wound. lf the said rod is perpendicular to the spindle, then the end surfaces of the yarn package are planes perpendicular to the spindle. If the slotted bar is ad usted in other positions, other shapes of yarn packages will be wound.
  • Fig. 4 shows an example of such an embodiment.
  • Part 101 is the traverse frame, 105 the traverse bar, and 120 the slotted bar, mounted on the traverse bar 105 and cooperating with the roller on the slide 128 which moves to and fro between the guide bars 118.
  • the bar 120 is adjustably mounted to the traverse bar 105 by means of bolts and nuts (not shown) which permit the slotted bar to be adjusted in various positions.

  • the slotted bar 120 can have various positions relative to the spindle, and can thus cause the winding of the yarn package with constant traverse length of various forms.
  • the bar 120 is prevented from turning over by means of a fork 532, which slides-over a fiat supporting rod in the frame 124. Due to the fact that the bar 120 cooperates with the roller 109 at the underside of the traverse bar, the traverse bar 105 will be moved to and fro with rotation of the traverse cam.
  • the bar 120 is mounted on the slide 128 by means of a bolt and nut 533, and can be fixed by means of a second bolt 535 in a circular slot, in the position suitable for causing the desired shapes of the yarn package to be wound.

It is obvious that this device can be dispensed with if the properties of the yarn to be wound permits this, in which case the yarn guide is replaced by a kind of convex yarn-guide which is capable of sliding over the surface of the yarn package.

  • FIG. 9 A form of the winding machine according to the invention for this purpose is shown in Fig. 9.
  • This machine corresponds in general to the machine shown in Fig. 1, with this difference, however, that the fulcrum 112 about which the lever 120 with H-shaped section swings is situated at the same side of the traverse frame 101 as the spindle.
  • the traverse length increases as the traverse frame 101 moves away from the spindle 117, as the distance between the small roller 109 at the lower side of the traverse bar 'and the fulcrum 112 about which the lever swings also increases during this'displacement of the traverse frame.

  • Fig. 10 shows such a machine. If it is desirable to wind a yarn package the traverse length of whichis smallest on the inside, then the fulcrum must be situated on the' other side of the traverse frame, i.e. the side'where the spindle is situated.
  • the yarn speed must, as a rule, be rather low, it may occur that the yarn speed sets a limit to the rotational speed of the spindle.
  • winding at a constant yarn speed is preferable to winding at a constant speed of the spindle, or at any rate it is desirable that, during the winding of the complete-yarn package, the-speed should be kept nearer to the maximum than in the case of constant spindle velocity yarn speed.
  • the application of friction drives with continuously variable transmission ratio is a known solution for this purposethe transmis-- s1on ratio being adjusted by the traverse frame whilst changing its position. In the machine according to the invention such variable spindle velocity can be obtained in a very simple and effective way.
  • FIG. 7 A first form of a machine with variable spindle velocity according to the invention is shown in Fig. 7.
  • the spindle 117 carries at one end the disc 171, which is capable of I sliding along the spindle, but which, owing to the presence of a key, can not rotate with respectto this spindle, whilst a spring presses the disc in the direction-of the shaft 175.

If the yarn speed is restricted to a low value, it is then, as a rule, admissible to arrange the relative position of ball carriage 112 and traverse frame 101 in such a way that the yarn speed is kept completely constant. In many cases, however, the traverse mechanism would then obtain excessive rotational velocities when the diameters of the yarn package are still small.
  • the extent of the adaptation is limited, and only such a change in the transmission ratio is possible as would cause the yarn speed to be equal to the maximum admissible yarn speed when the diameter of the yarn package is largest, and, when the diameter of the yarn package is smallest, would cause a rotational velocity of the spindle which does not surpass the maximum rotational velocity permitted by the traverse mechanism.
  • the point of contact between ball and disc must be situated at a distance from the centre of the disc which is larger than that separating the pressure roll from the axis of the spindle.
  • the transmission gear provided with balls has the important advantage that the balls are capable of free rotation in opposite directions, rolling on disc and shaft. when the ball carriage is displaced for the purpose of changing the transmission ratio.
  • the traverse frame is not subjected to noticeable forces exerted by the ball carriage.
