On the color graphics monitor 6 , therefore, color-coded pattern information elements for each course of the knitted goods are represented by one dot along the X-axis and color-coded pattern information elements for each wale by one point along the Y-axis. The input in the form of coded colors or color codes pattern information elements are stored in the image memory 5 . The image information stored in the image memory 5 is read in a sequence corresponding to the course of the knitting operations by a CPU 10 of the processor 2 and converted into pattern and control data for the required number of carriage movements, in an order given by a program is stored in a storage disk 11 . An example of a program stored in the disk for evaluating input pattern information is shown in FIG. 2 in the form of a flow chart.

In this means:

• P₀ Initialization of the evaluation table
  Evaluation tables for storing evaluation results are deleted.
• P₁ assignment of knitting information
  Pattern information items represented by color code numbers are transferred to the storage disk 11 and converted into knitting information based on the color numbers, for example, basic codes such as knitting, catching, skipping, wrapping, crossing, etc., the number of shift steps and special crossover data stored in the memory plate 11 are stored. This knitting information is ver used in step P₃ and the subsequent steps for determining and evaluating knitting operations.
• P₂ store knitting information for the next row
  Due to the knitting information obtained in the step P₁, it is decided whether or not a warping or the like must be prepared. For this purpose, pattern information for the next succeeding course is converted into one or more basic codes to be stored.
• P₃ producing a table of the stored code data
  Since the combination of knitting information items obtained in step P₁ determines the knitting style and / or the order of knitting, a table of the stored code data representing additional data indicating in which combination the knitting information items are stored is prepared.
• P₄ saving
  By this step, the volume of pattern and control data obtained by evaluating the knitting information is reduced to a minimum. In the illustrated program, the decision is made in this step, whether knitted according to the knitting B can be used in which the possibility given in the knitting machine of saving a Nadelaus choice is used.
• P₅ Making a cross-sorting table
  By checking the table of the stored code data prepared in step P₃ is determined whether one or more cross-over codes are present, which are optionally evaluated. How meshes are crossed depends on the number and type of mesh stitches to be made in a course. Therefore, a cross sort table is created only for the intersection codes.
• P₆ Verification of crossover codes for the left and right braids
  Crossover codes indicate that left and right stitches intersect each other. A left scramble code and a right scramble code represent a pair of scramble codes indicating that a braid pattern is to be made. The arrangement of these right and left crossover codes indicates whether to make a left or a right braid. Therefore, in step P₆, a check is made as to whether the code pairs indicate a left or a right cable pattern. For this purpose, a table of the pairs of intersection codes is produced.
• P₇ Determination of the number of needle pitches that are offset due to crossover codes
  The number of stitches across which a crossover occurs, that is, the number of grids between the two cross codes of a pair, is determined. By adding the thus determined number of grids to the number of cross codes, offset data is obtained.
• P₈ Check for catch codes
  By checking the table of stored codes produced in step P₃, the trapping codes contained therein are determined and, if appropriate, the type of each trapping code is designated by a mark.
• P₉ Check for cap codes
  The table produced in step P₃ the stored ten code data is checked for codes that hang around a hang to the right or left and the conditions if necessary, a transfer of one or more stitches from the front to the rear needle bed or vice versa. If such codes are present, a table is made in which they are stored according to their types.
• P₁₀ Check for codes to the left or right
  The table of ge stored code data prepared in step P₃ is the presence of codes for hanging to the left and / or right (left on the front needle bed, right on the front needle bed, to the left on the rear needle bed and / or to the right on the back needle bed), and any existing cap codes are evaluated. This evaluation determines whether the stitch is hanging on the front or back needle bed, how many needle pitches the stitch is to hang, what direction the stitch is to be put on, if there is a stitch on the target needle or not, and if there is any stitch on the target needle knitted on the front or on the back. Depending on this data, different knitting operations must be performed. The results of this evaluation are summarized in a table.
• P₁₁-P₁₅ verification of code data
  The table produced in step P₃ ge stored code data is checked for codes that be a hanging on the rear needle bed be thing, on capes and / or special codes and whether only knitting codes are available. The results of this review are saved.
• P₁₆ checking for the direction of a Zwischenumhängens
  A stitch that is to be relocated on the knitting machine to the right or left and, for example, on the front needle bed must be temporarily transferred to the rear needle bed (stitches on the back needle bed on the front). Thereafter, the front or rear needle bed must be offset in its longitudinal direction and then the stitch from the rear to the front or after a Zwischenumhängen on the front needle bed from this to the rear one umgehängt. In this step P₁₆, the knitting information obtained in the steps up to and including the step P₁₅ are checked for the existence of stitches in which such intermediate looping is required, and if necessary, the direction of interposing is stored.
• P₁₇ determining the direction of the direction of change
  The direction of each cape required due to a cross code or wrap code is stored (except for the directions of interim suspensions stored in step P₁₆).
• P₁₈ storing the direction of dislocations
  In the case of knitting patterns in which, due to the data stored in steps P₁₆ and P₁₇, a displacement is required, the direction (to the right or left) in which the back needle bed needs to be shifted is stored.
• P₁₉ optimization of the capping and crossing steps
  If data is stored in steps P₁₆ through P₁₈ derived from various types of code, such as wrap-around and cross-over codes, and this data causes repetition or redundancy, then measures are taken to avoid such repetition or redundancy ,

In the image memory 5 , for each carriage movement, the pattern and control data obtained by such a program are stored.

Connected to the graphic part 4 is a paper strip punch 12 which serves to punch pattern and control strips which are provided with holes representing the image memory 5 stored pattern and control data for each carriage movement. Connected to the processor 2 is a printer 13 which prints pattern information for knitting in color numbers and symbols, and pattern and control data stored in the image memory 5 for each carriage movement.

Now, whether for a knit A with the dargestell th in Fig. 3 knitting pattern explains how the pattern information are input to the recording apparatus 1 as the input pattern information in the device 1 are processed in accordance with that program, and what results are obtained by this processing.

On a flat knitting machine having two V-shaped needle beds, the knitted fabric A whose knitting pattern is shown in Fig. 3 can be knitted by attaching each indicated front loop to the front needle of a pair of front and rear needle pairs and each back stitch is knitted with a back needle. As a result, the pattern information consists of pattern information elements, which are each represented by a symbol and each associated with one or both needles of a front and the opposite rear needle needle pair of flat knitting machine with two V-shaped needle beds are assigned.

When the pattern information for knitting the fabric A is input to the recording apparatus 1 by means of a keyboard 7 and a joystick 7 ', each pattern information item shown in Fig. 3 is represented by a dot in one of the color codes indicated in the color code table , on the graphic color monitor in the colors having the code numbers 2, 3, 6, 12, 65, 66, 72 and 73, and in a mosaic-like tinting pattern pattern information elements for each course of the knitted fabric A along the X-axis and pattern information elements for Each wale of knitwear along the Y-axis are shown. The thus-input image information is further stored in the image memory 5 .

The series of pattern information items thus stored in the image memory 5 and displayed on the color graphics monitor 6 include needle selection and control information items encoded according to the color code table (Table 1). In the evaluation of these in formation elements due to the program shown in Fig. 2 and stored in the disk 11 pattern information for ten courses of knitting goods A in a sequence corresponding to the sequence of knitting operations in pattern and control data for twenty slide movements are therefore implemented.

It is found that the pattern information elements for the first, third, fourth, fifth, eighth and tenth courses of knitted fabric A only knitting operations on the front needle bed, knitting operations on the rear needle bed and catch operations, while no linking between tween a front knitted stitch row and an immediately preceding, back-knitted course and no displacement of the rear needle bed is required. For this reason, these pattern information items for each of these courses are converted into pattern and control data for one carriage movement each for the first, ninth, tenth, eleventh, sixteenth, and twentieth carriage movement ( Figure 5). In contrast, the second-stitch pattern information elements cause right or left hinges, namely a "3x3 mesh" pigtail and a "2x2 mesh" pigtail. For this reason, the pattern pattern information for the second course is converted into pattern and control data for seven carriage movements for the second to eighth carriage movement in Fig. 5. The pattern information elements for the sixth course include wrap information and are therefore included in pattern and control data for three carriage movements, namely the twelfth to fourteenth carriage movement in Fig. 5, converted. The information shown for the seventh course results in displacement of the rear needle bed and therefore is converted into pattern and control data for carriage movement, namely, the fifteenth carriage movement in Fig. 5, in which the rear needle bed is displaced. For the ninth row stitching is required. Therefore, the pattern information for this course is converted into pattern and control data for three carriage movements, namely the seventeenth to nineteenth carriage movement in FIG. 5.

In the recording apparatus 1 , pattern information items for each carriage movement inputted to and stored in the image memory 5 are automatically combined with the relative positions of the adjacent pattern information elements and the positions of each pattern information element relative to those for the preceding carriage motion due to the program evaluated and implemented in pattern and control data for the respective carriage movement and these data are stored in the image memory 5 . According to this data, pattern and control ribbons can be easily punched by means of the paper strip punch 12 . Further, the pattern information entered and displayed on the graphic color monitor 6 in the form of an image ( Fig. 4) may be printed out by the printer 13 , with pattern information for each course of the knitted fabric and pattern and control data for each carriage movement in the form of symbols or Mar. can be printed. While inputting the pattern information into the image memory 3 , the color graphic monitor 6 can be viewed. Further, the pattern information for the V-shaped needle beds arranged on the flat knitting machine becomes knitted fabric after being divided into pattern information elements each corresponding to one or two stitches hanging on one or both needles of a pair of needles consisting of a front and an opposite pair , Rear needle consists, entered in a code color or with a color code for the presentation of dots or grids, each representing a stitch or each consisting of a front and a back stitch mesh pair, ie in the manner in which knitting patterns are Darge , This input of the pattern information is very simple and can be easily made by a unge trained operator, the exact structure of the knitting machine is not known. An image appearing on the color graphics monitor 6 can be quickly drawn in the form of a painted line drawing and thereby corrected.

In the after entering the pattern information on the Graphic color monitor appearing image can be seen ent speaking the construction and the colors of the grids Pattern of the finished knitwear, so that due to this Image of the composition and pattern of the finished knitwear are readily conceivable. As a result, there is an advantage of the invention in that in a development the construction and pattern of a knitwear by one Designer directly on the graphic color monitor by making a rough sketch and correction of that on this one Well-designed patterns readily on a pattern swirl fen and / or a tax strip are held can, on the pattern data and / or control data for the Control of knitting operations of the flat knitting machine are recorded.  

The invention also has the advantage that the pattern information entered in the front direction can not only be recorded on paper by means of the paper strip punch 12 and / or the printer 13 , but also in the form of electrical data on any suitable record carrier, for example a floppy disk or a magnetic tape can be recorded.

That represented by the color graphics monitor and in the Image memory stored image can be at any time printed as a color image or photographed directly. If such an expression or such photo together with other recordings For example, a pattern strip and a control strip, can be stored, the one on such recording carriers recorded pattern information to one Capture view.
