Definitions

  • ABSTRACT A process for winding yarn into a cylindrical-bodied substantially flat-ended package by traverse winding layers of helical coils of yarn on a surface-driven package is improved by not only breaking ribbon formation by the known waveform (minor modulation of inverter output to the traverse motor) from a pre-set point, but also modulating the set point to create a major modulation having a minor modulation superimposed along or within the modulated set point waveform.
  • PAIENTEB was 1914* SHEEI 3 [IF 5 PRESET PQINT TIME PRIOR ART FIG.
  • FIG. 1 A first figure.
  • This invention relates to crosswinding of yarn, particularly to improved ribbon breaking for high speed surface driven winders.
  • the present technology of surface driven winders for synthetic fibers employs an inverter with a minor modulation of the electrical output frequency and voltage to drive the traverse motor and obtain ribbon breaking by varying the speed of the traverse cam with respect to the yarn delivery speed.
  • This method modulates the inverter output frequency by a fixed percentage about a pre-set point with a definite period of oscillation.
  • This invention improves ribbon breaking by modulating traverse rate in both a minor and major modulation.
  • the prior art minor modulation is a waveform superimposed along a straight line pre-set point.
  • Pre-set point is defined by the point shown in FIG. 5.
  • straightline pre-set point is meant the imaginary straight line described by tracing the pre-set point shown on FIG. parallel to the base line of the graph, as for example, Section C in FIG. 3 of U.S. Pat. No. 3,638,872.
  • This invention significantly reduces ribbons by modulation of the set point away from a straight line to cause the major modulation.
  • This waveform is a plot of frequency versus time for the electric input to the traverse motor.
  • FIGS. 4 and 7 Examples of this minor modulation along a major modulated curve are shown in FIGS. 4 and 7.
  • the FIG. 4 major modulated waveform is sinusoidal, while FIG. 7 is saw-tooth configuration in the major modulated waveform.
  • the minor modulation waveform of both curves is saw-tooth. Both curves repeat indefinitely.
  • this invention needs no simultaneous modulated drive roll speed to coincide with the modulated traversal rate. Also, it can be seen that it is unique with this invention to modulate the set point of the traverse rate as opposed to presetting it or presetting then decreasing it, while continuously superimposing the minor modulation along or within the modulated set point.
  • the prior art requires complex timing mechanisms and/or coordination of winding speed with traverse rate. Also, with initial pre-set method, each winder would require an inverter. The method of this invention permits driving many traverse motors from one inverter, and does not require the waveform to be timed with package size as the package builds.
  • FIG. 1 is a schematic showing a typical surface driven winder connected to inverters for the print roll and traverse motors.
  • FIG. 2 shows a preferred embodiment for modulating the set point for the electrical input to the traverse motor.
  • FIG. 3 shows the prior art, unmodified speed adjust.
  • FIG. 4 is an example of the waveform of this invention.
  • FIG. 5 is an example of the prior art waveform.
  • FIG. 6 is a bar graph showing the number of ribbons formed winding a package using a waveform of this invention.
  • FIG. 7 shows a wave form used to feed the traverse motor during the time the data was gathered for FIG. 6.
  • FIG. 8 is a bar graph showing the number of ribbons formed in the control experiment using the prior art waveform shown in FIG. 9.
  • yarn 1 is traverse wound through traverse device 2 powered by traverse motor 3 and transferred by print roll 4 onto package 5.
  • Electrical input to traverse motor 3 comes from traverse inverter 7 through line 9.
  • Electrical input to the print roll motor behind or within print roll 4 comes from print roll inverter 6 through line 8.
  • the schematic equipment shown within box 10 represents a typical surface driven winder.
  • the inverters have speed adjust knobs l1 and 12.
  • a method of modulating the set point is shown imposed into the circuit of speed adjust potentiometer 17 which is connected to inverter circuit 13.
  • a 360 rotating potentiometer 114 is connected with electrical lines 18 and 19 into the circuit.
  • a small motor 15 such as a clock motor rotates the potentiometer 14.
  • Motor 15 is driven by l 10 volts electrical source 16. This embodiment would be adjusted by speed adjust knob 12.
  • inverter circuit I3 simply has speed adjust potentiometer 17 which can be adjusted such as by speed adjust knob 11.
  • the waveform of this invention is demonstrated showing the output: frequency which is the electrical input for traverse motor along the vertical scale and time along the horizontal scale.
  • the amplitude of the minor modulation is shown to be the distance between the tips of the arrows labeled 20.
  • the amplitude of the major modulation is shown to be the distance between the tips of the arrows labeled 21.
  • FIG. 5 shows a typical prior art waveform having a pre-set point showing a straight line about which the amplitude of modulation varies by a minor amount.
  • FIGS. 6 to 9 are bar graphs and waveforms which are explained in the following example.
  • EXAMPLE Textured 2,600 denier yarn was wound at 4,500 feet per minute using the prior art waveform for traverse rate as compared to the waveform of this invention.
  • the same yarn was used for both the prior art control package and the package using the waveform for traverse rate of this invention.
  • the yarn had standard finish, 36 entanglements per meter, 12 crimps per inch and was wound onto package having a final diameter of 9- inches and weighing 11 pounds.
  • the winding time was 15.5 minutes.
  • the waveform when the package was wound according to this invention is shown in FIG. 7.
  • the results in the number of ribbons formed per 30 second (one-half minute) interval are shown in FIG. 6.
  • the prior art waveform for the control wound package is shown in FIG. 9.
  • the minor amplitude should be 1 to 6 percent, preferably 2 percent.
  • the period of the minor waveform should be 0.5 to 5.0 seconds, preferably about 2 to 3 seconds.
  • the amplitude of the major waveform should be 2 to 12 percent, preferably about 8.
  • the period of the major waveform should be 0.25 to 2.0 minutes, preferably about 0.5 to 1.0 minute.
  • the amplitude of the minor waveform should not be greater than 50 percent of the major amplitude.
  • the major modulated waveform can be generated using solid state electronics such as with capacitors. Also for just one winder in special circumstances, the potentiometer could be rotated by hand.
