  • the coneholder 20 is brought down into contact with the drive-.roll'15 the follower roller 47 slides down to the bottom. of the inclined groove or guideway 45 in the cam-track 40.
  • the pur ose of the adjusting-means for the camtrac 40 is to provide that the track may be set in proper relation to the cone-holder 20 to insure that the latter will bear evenly along the whole length of the drive-roll 15 as shown in Fig.
  • the two grooves in the traverse-cam are of difierent pitch or lead to provide for regulating'the traverse of the thread-guide in accordance with the type of package being wound; one groove being operative on the guide when the ma Y chine is employed for Winding cones and the other groove being used when the machine is ad usted for winding cylindrical packages.
  • the present invention is concerned only with the Winding of conical packages ment,..as noted in the patentpreviously re and the groove 7 in the cam 5 is plotted with a progressively changing pitch or lead for the purpose of accelerating the speed of the thread-guide as it traverses toward the smaller end ofthe cone and correspondingly retarding its speed as it moves toward the base of the cone.
  • the object of this arrangeferred to is to cause the yarn to be laid on the cone-holder with the coils or helices having an increased pitch or lead toward the apex end of the cone'as compared with their disposition at the base end thereof. This results in the yarn building up faster at .the base of the cone than toward its apex end so that the taper on the surface of the package. gradually increases from start to finish of the winding. This increase in the taper takes place as the cone-holder 20 reg cedes-from the drive-roll 15, and to provide that the surface of the winding, notwithstanding its change in taper or conicity, be
  • the cone-holder be tilted to progressively increase the angle of inclination of its axis with respect 'to the drive-roll as the holder recedes from the roll.
  • the arm swings upwardly about its pivot 35, and meanwhile the bearing member 22 is rocked on its pivot 29 under the action of the. cam-track '40. That is to sayfas the cone-holder 2O rises away from the drive-roll 15 the roller 47 on the arm 46 slides through the cam-groove. 45, and since the groove is inclined at an angle to the normal vertic path of the arm longitudinal direction of its base.
  • the tilting of the cone-holder 20 will also cause it to be shifted bodily in the I Stated briefly, the tilting of the cone-holder on an axis out of line with its own axis causes the holder to be displaced bodily to the right longitudinally of the drive-roll 15 during the movement of the holder away from the roll.
  • the layers of'yarn deposited on the cone-holder will be gradually and progressively stepped forward in, the direction of the apex of the cone as indicated by the dot and-dash lines in Fig. 4.
  • the yarn will be built up in a mass which not only has a gradually increasing taper on its peripheral surface, but
  • the convexity of the base tends to prevent over runs or loose coils of yarn at this 'end of the cone. That is to say, where the yarn coils reverse at the base end of the conethey are supported in more stable relation and restrained from slippingout of place, thus preventing overruns, cobwebs or loose loops which would be apt to impede the free delivery of the yarn when it is drawn oil over the apexend of the cone.
  • the yarn is disposed in smooth level layers to form a uniformly dense, compact package of true contour in accordance with the prescribed degree of taper on its surface and convexity at the base.
  • the coneuilder mechanism is reduced to the simplest and most direct form by mounting the cone-holder on the swinging arm 30.
  • the cam-track or guide 40 which controls the tilting action of the cone is of relatively short length and its control of the cone-holder through the roller 47, arm 46 and bearingmember 22. is made more direct, resulting'in a close coupling which eliminates backlash and lost motion and therefore insures a more positive action for the purpose described.
  • the builder-motion is compacted and condensed within a-minimum space to reduce the dimensions of the whole machine.
  • the simplicity of the mechanism also makes for greater ease of operation, and insures against its becoming deranged or getting out of order.
