Definitions

  • the present invention relates to a method for sewing stitch pattern groups on a zigzag sewing machine according to the preamble of claim 1.
  • the invention further relates to a stitch pattern group produced by the method.
  • Household sewing machines reach stitch widths between 5.5 and 8 mm depending on the hook system used in the machine. Even if a maximum stitch width of 8 mm is assumed, only single samples of a maximum of 4 mm can be produced in two rows, and only a maximum of 2.7 mm field size in three rows. If, therefore, the side length of a square field corresponds to only a fraction of the maximum width of the machine, the pattern size obtained is insufficient for many applications. According to the methods known from German Patent 32 34 864, different stitch sequences within the pattern are required for the different basic patterns, so that the stitch of the last stitched pattern, which forms the starting stitch for the next pattern, can be placed in any corner of the square field .
  • the stitch sequences required to set the end stitch in the corners of the basic pattern require up to three intermediate stitches at the cross point of the diagonals in the geometric center of the square field, which is represented by the cross stitch. These intermediate stitches interrupt the diagonal course of the thread within the cross-stitch and the greater the number of intermediate stitches required, the smaller the number of threads running continuously over the entire diagonal of the square field.
  • the uneven number of diagonal threads and intermediate stitches in the individual basic patterns results in an inconsistent appearance of the different cross stitches within the pattern combinations. The inconsistent appearance becomes clearer the larger the square field is chosen for the individual patterns.
  • the invention seeks to remedy this.
  • the invention as characterized in claim 1, solves the problem of creating a method for sewing stitch pattern groups on zigzag sewing machines, with which cross-stitch patterns can be produced, which consist of stitch lengths that have the maximum stitch width of the machine.
  • B is the maximum overstitch width range (short overstitch width) within which the needle of a sewing machine forms a stitch, ie can pierce the material
  • T denotes the pattern length sewn depending on the width of the individual pattern.
  • the pattern length T in FIG. 2 corresponds to the maximum feed length of the material feed conveyor.
  • the two sewing patterns M1 and M2 are made up of two parts of the overstitch width range B, in which the width of the smallest individual pattern M1 and M2 is therefore at most equal to half of the overstitch width range B.
  • the thread length mentioned corresponds to the maximum feed length of the feed dog.
  • the neutral position N of the needle lies in the middle of the overstitch width range B.
  • To generate the pattern M1 starting from the neutral position at position A (start), the sequence 0 to 6 is set, with "0" the start stitch and "6" represents the final stitch E.
  • start the sequence 0 to 6 is set, with "0" the start stitch and "6" represents the final stitch E.
  • the thread sections f are set.
  • the first two thread sections f between the punctures 0 and 1 extend diagonally over half of the maximum overstitch area B; the third and fourth thread section from the stitch 2 to the stitch 3 or from the stitch 3 to the stitch 4 still extend over a quarter of the maximum overstitch width range B in order to cross the crossing point at the stitch 3 to the stitch 4 on the second leg or thread section of the cross in Arrive pattern M1.
  • the next crosshair can be formed by forming a further thread section between the stitches 6 and 12, which is at a right angle and adjoins the end point E.
  • this cross In contrast to the crosshair in M1, this cross has two punctures at the cross point of the diagonals and contains only two threads running across the entire diagonal, while four threads each run only across half the diagonals.
  • a first multi-thread zigzag seam with an even number of threads and a stitch length which corresponds to the set stitch width is sewn, alternately at least two zigzag stitches in a first feed direction and the same number of zigzag stitches are sewn congruently in a second feed direction opposite to the first.
  • the first and the last stitch of the at least two-thread seam section coincide.
  • an intermediate stitch Z8 must be set in the middle of the first thread section between the stitches 1 and 2.
  • the stitches 13, 14, 15 are then set, which are congruent with the stitches set at the beginning of the second zigzag seam.
  • stitch 15 three cross-stitches are completed. So that a further cross stitch pattern can now be attached to the end of the first cross stitch pattern, the congruent stitches 16, 17 and 18 are also set to the end of the pattern. The machine is then preferably stopped with the needle lowered.
  • each zigzag seam consists of only two right-angled stitches, which creates two cross-stitches.
  • a larger number than three cross-stitches can be created.
  • the multi-thread zigzag seam with an even number of faders consists of two or four congruently stitched zigzag seams, while the multi-thread zigzag seam with an odd number of threads consists of three or five congruently stitched zigzag seams.
  • the zigzag seam with the larger number of threads is sewn last because it has the intermediate stitch Z required to achieve an opposite zigzag seam completely invisible.
  • the start and end stitches of the stitch pattern group are opposite for groups with an odd number of individual patterns in the feed direction, but on the same side of the stitch field, while for groups with an even number of individual patterns, these stitches are also on opposite sides of the stitch field.
  • FIGS. 5, 6 and 7, three possible combinations of pattern groups are explained, for example, which are composed of stitch pattern groups according to FIG. 3.
  • the start and end stitches of the two stitch pattern groups are dotted and the Letters A, B, C and D or E, F, G and H denoted.
  • a first group of three A1 to D1 is sewn starting with A1.
  • a second mirror-image stitched group of three whose first stitch A2 coincides with the last stitch D1 and consists of stitches A2 to D2.
  • This is followed by a further, corresponding to the first stitch pattern group with indices 3, in which the pattern start A3 coincides with the pattern end D2.
  • the pattern end D3 forms the beginning A4 for a stitch pattern group with indices 4, which is arranged at right angles to the first three stitch pattern groups and is in turn sewn in mirror image.
  • the remaining stitch pattern groups with the indices 5,6,7 and 8 are sewn, which are point symmetrical to the first four stitch pattern groups with the indices 1 to 4.
  • the pattern group combinations can of course also be created in the opposite direction (clockwise).
  • Figures 8 and 9 show stitch pattern group combinations composed of stitch pattern groups with different numbers of crosses.
  • the operator also stores the stitch pattern groups with different numbers of cross-stitches lined up in the machine's electronics. This saved data can be called up in any combination and is then automatically sewn by the machine.
  • the needle preferably remains in the sewing material after a stitch pattern group has ended, so that it can, if desired, be rotated accordingly before the next stitch group starts to be sewn automatically.
  • the machine for sewing the following stitch pattern group is started by pressing the starter of the sewing machine again.
