Definitions

  • the invention relates to a method for forming textile patterns with fancy yarns on a playback device.
  • the invention further relates to an apparatus for performing the method.
  • CAD computer aided design
  • the fancy yarn forms under consideration are recorded freehand by an electronic stylus and thus entered into the computer.
  • a variation of the textile pattern by varying the fancy yarn was not possible or was only possible with great difficulty.
  • the invention is therefore based on the object of making the formation of textile patterns with fancy yarns simple on a playback device and with possible variations for the fancy yarns.
  • the data signals belonging to basic forms of fancy yarns are stored, the storage being carried out with variable parameters.
  • the basic shapes can be called up on the playback device and varied by entering the desired parameters, so that variations of the textile pattern are also possible at any time through variations of the fancy yarns.
  • the storage of the basic shapes has the advantage that new fancy yarns can also be created and their effects can be checked in a textile pattern.
  • the device according to the invention for carrying out the method has a memory in which basic shapes of fancy yarns are stored in a parameterized form.
  • FIG. 1 shows an example of some geometrical partial shapes with their parameters that can be used for the formation of fancy yarn shapes.
  • a circular element 1 is shown in the form of a semicircle.
  • the parameters of this circular element 1 are its radius r, the thread thickness d and the position of the ellipse in the plane.
  • Figure 1 b shows an ellipse element 2, the parameters of which are the long axis a and the short axis b.
  • Figure 1 c shows a spiral element 3 with the parameter thread thickness d, outer diameter D of the spiral element 3 and the pitch of the spiral.
  • d parameter thread thickness
  • D outer diameter
  • the thickening element shown in Figure 2 is based on the thread thickness d, which widens approximately sinusoidally to the largest diameter D ', also sinusoidally goes back to the thread thickness d in order to then form a new thickening.
  • the distance a between the maximum diameters D ', the maximum diameter D' and the thread thickness d are parameters of this thickening element.
  • FIG. 3 shows a pimple thread 6 with two pimples 7.
  • the parameters are thread thickness d, spacing of the pimples on diameter d1 of pimples 7 perpendicular to the thread direction and diameter d2 of pimples 7 near the thread.
  • Other parameters are overhang h1 of knobs 7 over the thread upward and overhang h2 downward.
  • Figures 4 to 8 show fancy yarns with multiple threads.
  • Figure 4 shows a flame shape 8 with a twisted thread as the base thread 9 with the diameter dF, which strengthens over a length LF to a maximum cross-section DF by a thickening of one of the threads and tapers again to the initial diameter dF, a symmetrical figure arises.
  • the parameters dF, DF and LF are supplemented by the distance aF between two such thickenings.
  • FIG. 5 shows a caterpillar shape 10 with a basic thread of diameter dR, which is formed from a thick thread 12 and a thin thread 13.
  • the thick thread 12 is spirally wound over a length LF to form a bead 14 and then merges again into the basic twisted shape 11.
  • Parameters of this caterpillar shape 10 are the diameter dR of the base thread 11, the length LR of the caterpillar 14, the outer diameter DR of the caterpillar 14 and the distance aR of two caterpillars to one another.
  • FIG. 6 shows a helix 15, consisting of a thick thread 16, which is wound essentially spirally around an elongated, thin thread 17.
  • Parameters of this helix shape 15 are the diameter DW of the helix formed, an angle of inclination ( ⁇ ), that of the thick thread 16 with the perpendicular to the thread extension includes and the height HW of a helix, which corresponds to the repeated element of the helix shape 15.
  • FIG. 7 shows a loop thread 18 which consists of three threads 19, 20, 21 twisted together.
  • a thread 21 forms circular shapes 22 projecting laterally from the longitudinal extent of the loop thread 18, alternately on both sides of the loop thread 18.
  • Parameters of the loop thread 18 are the diameter DL of the circular shape and the distance aL, here measured on circular shapes 22 of adjacent loop arrangements lying on different sides.
  • FIG. 8 shows a bouclé element 23 consisting of three threads 24, 25, 26, two of which are spirally wound around one another and a third thread 26, which is wound in a wave shape around the other two threads 24, 25, each with a clear distance from them forms two threads 24, 25.
  • this bouclé element is the outer diameter DB, which results from the outer dimensions of the loops of the thread 26 on both sides of the element 23 and a distance aB between two legs of a loop of the thread 26.
  • the basic elements can be varied in size and shape and the effect of this variation on the textile pattern made with the relevant fancy yarn can be seen on the screen. Special effects can be achieved if a statistical variation of the or some parameters for a pattern is permitted.
