DE4329875A1 - Device for developing a control program for a knitting or knitting machine - Google Patents

Abstract

An arrangement (10) is disclosed for developing a control program for a knitting machine or loom (42) used to produce hosiery in which the thread runs across the knitting direction. The arrangement has an input unit, a graphics unit and a control program calculating unit. In order to make it easier for the user of the arrangement to convert input information about the weave pattern to be knitted into a knitting control program, the input unit is designed to allow inputting and/or placing weave, colour and/or contour patterns. An adapter unit (28) for weave arrangements with at least two different patterns following each other in the direction of the stitch rows checks whether the patterns can be knitted.

Description

The invention relates to a device for developing a Control program for a knitting or knitting machine position of a stitch product with a thread course transverse to Production direction, according to the preamble of claim 1.

With the knitting or warp knitting machines in question, it can flat knitting machines, especially with two needle beds are flat knitting machines or circular knitting machines machines with tip needles, latch needles or the like are prepared. The thread course is transverse to the manufacturing direction tion of the knitted fabric, so that according to the German language need to be spoken of a single thread knitting, if it has been produced on a knitting machine, or by Single-thread knitted fabrics, provided a corresponding knitting machine has been set.

Modern knitting machines offer a variety of possibilities ten in the design of the knitted fabric, since the thread optional run in the manufacture of the knitted fabric through the use of appropriate control mechanics or electronics tronics can be individually varied. The control commands are in previous knitting machines often using jacquard Cards of the knitting or knitting machine carried out. In youth The control commands are made with the help of magnetic Storage means such. B. magnetic tapes or disks of Ma machine supplied or directly via data line. With In principle, these modern knitting machines can be Ma products with complicated bonds, different weave patterns, complex color patterns and meshes Create a certificate outline. From the textile industry  also increasingly appropriately designed stitches requires products, due to the short fashion cycles What matters is that a template developed by the designer for Shape, weave structure and coloring of the knitted fabric is implemented in production as quickly as possible.

The implementation of the design in the corresponding control program So far, however, has been extremely time-consuming and requires speci All knowledge regarding both the knitting technique and also in relation to electronic programming technology. Ins especially the joining of different ties ster has so far required the intervention of one specifically for this educated person since in general the binding arrangement not from the two adjacent weave patterns is knitable. It must then be done by hand by means of an appropriate programming the knitting tolerance of both patterns getting produced.

From the trade magazine "knitting and knitting technology" 41 (271, pages 668 to 670) is a facility of the beginning known type known. With this prior art, based on a multicolored image template and the specification the desired type of knitting jacquard or intarsia, the steering wheel program for the previously selected knitting machine with help the control program computing unit automatically created. over a control program can run separately can be changed in such a way that a specified outline shape is also possible of the knitted fabric is taken into account when knitting (Form knitting). There can also be binding patterns with more or less complex attachment structures are taken into account, by explicitly entering corresponding program parts in the SINTRAL program language. To represent the bond a color cartridge is used with assignment of the use colors for binding elements and modification elements. After the SINTRAL control program has been calculated by the control program computing unit can choose the binding also in a thread run display mode or a stitch  display type can be displayed on the screen. With The SINTRAL control program can use an analysis program be tested. Detected program errors are displayed shows for subsequent manual correction by the at the Machine working specialist. A change z. B. the thread is carried out by the expert in that the SIN TRAL control program changed accordingly. To the impact of these control program changes on the thread run To be able to determine, the SINTRAL control program must created and a simulation run for the previously selected machine type can be carried out for subsequent Play the resulting thread line on the screen. The control program arithmetic unit is unable to a template with several arranged side by side, under different binding patterns automatically a control program to calculate; in this case, the model must the working specialist has the necessary program Enter steps in the SINTRAL programming language.

From U.S. Patent 4,608,642 (Shima) it is known to bind enter structures using a color code with 127 colors, each of a needle or a pair of needles of the respective Stitches are assigned and determine the weave sequence This binding process is predetermined and partly dependent on the machine type. With the help of the control program calculation the control program for the previously selected one Knitting machine created automatically by the color codes in the corresponding knitting sequence are transferred. Knit-Un tolerances involved in running the program Errors, such as B. fixation of a mesh crossing, opposing bed misalignment or excessive mesh stretching, are not recognized by the computing unit. For more colored knitted fabrics (jacquard or intarsia) is a limited Number of colors reserved. A multi-colored picture template therefore can generally not match the original colors are reproduced. For a limited number of re corresponding color codes can be selected.  

The juxtaposition of color patterns and binding structure ren is due to the double meaning of the color codes (binding and color) only possible to a limited extent. After simulating the generated program can be a mesh display on the screen respectively. However, changes can only be made in the color code display position or in the knitting program itself, whereby for The changes in the mesh display are displayed again the complete program is created and a simulation run must be carried out.

The invention has for its object a device to develop a control program for a knitting or To provide knitting machine of the type mentioned at the implementation of information entered about to stric binding pattern in a knitable control program is lighter.

This object is achieved by the characterizing Features of claim 1 solved.

The adapter unit therefore checks the at least two of the bin juxtaposed pattern forming arrangement there are binding, color and / or outline patterns within the im generally all or part of the stitch product such as e.g. B. sleeves, descriptive overall arrangement. If you go with for example, of two binding knits that can be knitted individually star off, e.g. B. retrieved from a corresponding biblio thek, so in many cases there is a knitting Incompatibility when you mesh these two patterns row direction side by side. For example, follows a pattern on a common row of stitches geoperation in one of the two possible directions, where other bond pattern, however, in the other Rich tion, these two operations cannot be carried out within the single sled run. The customization unit therefore checks all information about the two patterns, especially all lines of the thread  Illustration then as to whether such an intolerance occurs. If she finds such an intolerance, then corrects it according to an embodiment of the invention the binding information about both binding patterns in the Way that the two opposing necking operations in two successive sled runs the.

Detects knitting incompatibility adjuster that cannot remove them automatically, so it gives according to ei ner embodiment of the invention a corresponding error deregistration.

Overall, there is a significant relief in the Development of the knitable control program with conform the reduction of the time required for this, since the adapt ß unit knitting incompatibilities automatically eliminated, or an intolerance that cannot be corrected immediately issues the corresponding error message.

A particularly preferred further development of the fiction moderate device is characterized in that the adaptation Unit for the transmission of the corrected binding arrangement or the error message to the graphics unit for optical Reproduction of the corrected binding arrangement or the original original binding arrangement including error message and that the graphics unit for manual correction of the reproduced binding arrangement via the input unit and for the transmission of the manually corrected bin arrangement to the adapter for re-checking the knitting tolerance is trained. this makes possible an interactive control program development with reduced Development time, since in dialogue between the operator and the device according to the invention Adaptation unit immediately checked by the operator and if necessary can be further corrected with immediate Checking the compatibility of knitting without a complete  tes tax program that can be run on the respective knitting machine gram would have to be created.

After the interactive completion of a knitted bin arrangement of the several patterns can finally Control program can be calculated, including the adaptation unit the control program computing unit is connected for transmission development of the corrected stitch arrangement and for subsequent Calculation of the tax program.

In order for the correction according to the invention with the aid of the adaptation unit and thus in principle knitable stitch arrangement without all too much computing on the multitude of currently or knitting or knitting that will also be used in the future To be able to manufacture machines, it is proposed that the Control program computing unit a first subunit for loading calculation of a general knitting machine type-independent Control program includes. It was found that the large variety of current knitting machines a series essential design features in common. It will be there here for one who has this in common. It is therefore for one these common design features "univer selle "knitting or knitting machine a corresponding tax program created. From this universal control program can now be machine-specific with little effort Control program can be derived, the corresponding Computer module also integrated in the respective knitting machine can be. The centrally developed universal tax programs can then be sent directly to the individual knitting machines bar can be supplied.

In a further development of the invention, the input unit is for the independent input of binding patterns, Color patterns and outline patterns trained. After the correspond appropriate input, possibly also using Bi libraries for weave patterns, color patterns and outline patterns, can then enter the binding pattern or color pattern entered in each case  ster or outline pattern further revised for each will. Then the weave patterns, color patterns and The final outline is superimposed on the computer, and finally the control program for the desired stitch to get the product. The erar during this development prepared versions of weave patterns, color patterns or Ma Product outlines can optionally be included in the corresponding Library for storage, which the Ein unit connected to a corresponding data storage is.

According to an advantageous further development of the invention provided that the bin in the thread representation formation pattern from bin formed by the binding elements rows of extensions as well as from the modification elements Modification series exist, and that the lines of binding arrangement of the joined rows of binding mu are formed. This special way of representing the Thread run is for those with the manufacture of stitch products nissen confidants particularly useful because the manufacturing process is striking according to the course of the castle. Also give the modification elements such. B. reassignment, dropping and offset at what he did with the appropriate action is sufficient, but not as is the case with the concrete knitting or knitting machine type is carried out in detail. The The display type is therefore independent of the machine type. Indeed the number of lines is practically always greater than that number of rows of stitches because of the rows of stitches of the product corresponding series of bonds in many cases len follow one or more series of modifications.

In addition to all the necessary details of the bond manufacturing specifying thread path representation can be in egg ner further development of the invention also optionally a sym bol display type can be selected, which from the individual Ma rows of symbols each assigned, where each symbol the thread guide around a pair of needles and at  at least part of the wall to be carried out subsequently operations. This type of representation has the intent part of the closer proximity to the appearance of the Maschener certificate, if only a part, preferably only that next subsequent modification operation is displayed with. A another possible type of representation is the mesh representation type of development, which is an already quite realistic image of the reproduces knitted fabric. It will here mesh rows are shown, each of the stitches rows are assigned and formed from mesh elements where each stitch element represents a stitch pattern, a representation of a corresponding section of the manufactured mesh product corresponds. These stitches Images can be photographed by scanning appropriate ones Detailed photographs of finished knitted fabrics made and be retrievably stored element by element in a library.

An advantage of the thread running representation type according to the invention lies in the fact that generally between rows of bonds and deviations a distinction is made between series and that each run and return of the lock is assigned a line. Two different weave patterns are juxtaposed sets with different succession of ties hen and series of modifications, it must be ensured that all binding rows of both patterns are at the same height be brought so that each one is a continuous bin line can be formed by a single run of the Castle can be processed. According to the invention this alignment of the bond rows of the two binders ster manufactured by the adapter unit, that the bond row without connection to a bond row of the each other binding pattern by inserting blank lines under the relevant "lonely" line of bonds for so long is moved up until the isolated row of bonds on egg ne subsequent series of bonds in the other pattern meets. As a result, the display follows in one line only binding elements or only modification elements  each other so that a knit connection of the two next to it interlocking weave pattern is made. It results such a nesting of the constructive structure different binding structures, by after a line with Binding elements as many rows with modification elements ten follow as the two structures to be adjusted to the maximum following the tie line. As part of the further adjustments of the two binding patterns, however, can further modification lines can also be inserted.

A knitting incompatibility can also arise when joining a row of ties without misalignment one of the two Tie pattern a row of ties with offset (one of the at the needle beds) of the other weave pattern closes. If in this case due to the offset a mesh crossing of right binding elements (mesh or Handle) with left binding elements (mesh or handle) in the results in a different bond pattern, this crossing by laying the thread in the course of the current bin line fixed. This leads to a change in the con structure compared to the two output bin patterns that must be avoided. The adapter in this case automatically moves all of them Rows one of the two binding patterns, so that in Ver run the shift row with offset next to this shift one series of bonds of the other pattern comes, in which there is no corresponding intersection at Exercise of a needle bed occurs.

In the course of this mutual shift of the two bin In turn, the adapter unit automatically provides the sample for that after their displacement the rows of bonds and the Modification series are aligned with each other under On addition of corresponding blank lines.

Which of the two binding patterns compared to the total ten binding arrangement is shifted, and in which of the at  the possible directions is, in itself, for making the Knitting tolerance irrelevant. It is particularly useful it, however, if that bond pattern is shifted, which was last entered in the binding arrangement that is. The binding patterns entered so far, which in all mean already with regard to knitting compatibility have been adapted to each other, then remain stationary and do not have to be mutually adapted again.

The shift in the respective binding pattern takes place in this way often, until the adapter unit determines that none of the time len more a mesh crossing with subsequent fixation arises. If this goal cannot be achieved, there is the adapter unit issues the corresponding error message.

So that the binding pattern to be shifted is completely preserved remains ten, it is appropriate that the adapter unit the bin shifted in one direction at most until the corresponding edge of another weave pattern or or overall arrangement is reached. To cross the border to avoid the overall arrangement from the outset is pre- suggest that the adapter move the tie pattern towards moves away from the closest edge of the overall arrangement.

If the two binding patterns in Ma rod direction (perpendicular to the row direction) peri are constructed odically, with one usually as a repeat length of the designated period, it is sufficient if you shifting speaking binding patterns until a maximum of one Total shift corresponding to the larger repeat length of the both binding patterns is carried out. If after this ma ximal shift still a mesh crossing an error message is issued.

For the sake of simplicity, one becomes the binding binding in question ster up, d. H. to knit towards the last one postpone the end of the overall arrangement because in this  Direction generally the review and if necessary itself the lines are corrected. But then when the e.g. B. from the repeat length of the binding pattern involved guided maximum total shift the distance of the bin pattern from the end of the overall arrangement let the adjustment unit that the binding pattern in question in Opposite direction, i.e. towards the beginning of the total arrangement tion, is moved. The same applies in the event that between the weave pattern and the end of the overall arrangement there is a binding pattern, with the distance to the next one following bond pattern with the maximum total shift is compared.

Only reassignment processes are permitted in a modification line, where the distance between the start and finish point is the same are (same cape distance). Even if, as before is exposed, the two initial binding patterns each are knitable by themselves and therefore meet this condition, it can happen when the two binding patterns are put together ren that in a modification line modification elements "Um hang "occur with different cape distance. In this case, the adapter unit separates the two corresponding series of modifications of the two bond patterns by placing an empty row in one of the two binding patterns is inserted. This is equivalent to the insertion an entire blank line and then resetting the rows of one of the two bin following the blank lines pattern around a row.

That binding pattern is preferred by the adaptation unit reset by a row, the conversion element "Um hang "has a comparatively larger cape distance. It is generally expedient to solve the problem scissors of the two hang operations, namely the one with the longer distance, to be carried out first since then the Ma are drawn closer and thus another cape ration offer greater resistance.  

Another condition for knitting multiple ab change elements "reassignment" is in a modification series that of the same direction. If this condition is ver Finally, the adapter unit again separates the two walls rows by inserting a blank line and the like Reset one of the two binding patterns by one row.

The operation "reassignment" is done with the help of thread Spreading elements made on the needles of the knitting machine. Due to the local conditions, it is cheaper that Moving to the left in the needle bed grid before moving to right. The adjustment is preferably staggered therefore the series of modifications in exactly this order.

There are at least one pair in a row of ties interconnected left or right binding elements (Stitch or handle), a subsequent cape can can only be carried out if the removal of Start and end of the transfer process a certain limit does not exceed. This limit depends on whether the Binding elements of the pair at the beginning of the transfer process from be moved away or towards each other. In the former There is a small trap for all possible bin pairs of the same element. In the latter case this limit is in the range of twice the distance of the binding elements. When checking whether this critical order hanging operation is feasible, any interim temporal reassignment operations are taken into account. It it is possible that after performing such a between temporal reassignment of all binding elements are on one side. In this case the cape is ration possible.

However, if the latter reassignment operation is critical Neck operation follows, the latter can neck operation not be performed unless the two operatio  and with them the corresponding modification lines reversed. This swap is caused by the adapter carried out on a trial basis after this the impossibility possibility of carrying out the critical necking operation Has been established.

If this measure does not lead to the desired result or if there is no further one on the relevant modification line Modification line follows, the adapter goes in the way before that before the relevant modification line (= capes line) inserts an intermediate line with modification elements "Cape", which ensure that all binding elements either only right binding elements or only left binding elements elements are, provided that there are no needles be occupied twice. To the bond structure as such not to be changed, one will follow the cape line Modification line inserted with modification elements cape, which the when adding the previously added line undo guided reassignment operations.

If the condition that no needles are used twice, is not feasible, the adapter unit again gives a mistake registration.

According to a further very advantageous embodiment of the Invention is the adapter for checking the Knitting compatibility when overlaying a color pattern a basic knitted fabric is formed. Preferably adapts unit again makes an independent correction if she found that when superimposing color mu star on a basic knitting intolerance at the bin arrangement occur. In the event that the adapter itself is unable to resolve the intolerance ben, in turn, as previously described, an error message.  

Preferably, when overlaying a color sample on a basic knitted fabric the Ver Inactivities in succession according to the previously explained processes. Alternatively, it is also possible Lich, the entire knitted fabric regarding the weave pattern too check and correct if necessary, and only after that further procedure for adjusting the basic knitted fabric make the overlaid color pattern or vice versa.

A particularly advantageous embodiment of the invention in Connection with the overlay of the basic knitted fabric with egg Nem color pattern is that the color pattern selectable Knit styles, such as an intarsia or a Jacquard knitting, but also a so-called transparent Knit type is assignable.

A transparent type of knitting means the following. When partially overlaying a basic knitted fabric with egg Nem color samples are usually only rectangular color samples intended. However, to round or any color must To be able to form stereotypes, the rectangular area those areas that match the color pattern should not be assigned in the color of the basic knitted. These areas, for example the outside areas of a heart pattern within the rectangular, above Color samples taken, so in the so-called Transpa rent-knitted style where these areas come in handy represent the basic knitted fabric.

In the intarsia knitting process in which the different ge dyed threads changed during the pattern transition in the knitting process it is particularly advantageous if the type of binding you can choose between two colors for this transition. As Ab type of binding is the way of connecting the color areas with to understand the basic knitting. In this case, too advantageous, the location of the binding and the type of binding elements, for example long or short handles or Ma  selectable. The location of the binding elements can be specified alternatively, but also ge automatically be chosen so that the operator of the facility in this case, no thought about the choice of location Chen needs.

If the jacquard knitting process is selected as the knitting method, then it in this case according to further embodiments of the Er possible, placed the jacquard knitting area or un placed, in the latter case over the entire Grundge to choose straight away. In the case of a placed Jacquard knitting area in the basic knit is according to the width Ren embodiments of the invention are alternatively possible Back of the jacquard knitting area as a net, if necessary with different network structures, as twisted networks or as nets with basic knitted fabric, so the thread of the basic knitted fabric is continued in the background form.

With the jacquard knitting in contrast to the In tarsia knitting a multicolored back is formed, is a knitted structure under the term net hen where the pattern-forming color thread is not on the back side, i.e. not knitted on the net.

The network structures, i.e. the structure of the back of the Jacquard knits can be structured differently. For example, the non-pattern-forming color thread in the Network of every second, third, fourth. . . up to every eleven knitted ten needle in the rear needle bed, so that optionally 1: 1 networks, 1: 2 networks, 1:11 networks can be provided nen. Body, on the other hand, becomes the pattern-forming color thread as well as the non-pattern-forming color thread on the Reverse 1: 1 knitted.

According to a further embodiment of the invention, the Jacquard knitting area also as a so-called cross tube  that is created by any non-patterning, So the needle on the back, complementary to the pattern, d. H. knits on the back needle bed. This creates Tubular knitted fabrics, the pattern-forming and non- Cross the pattern-forming threads when changing colors.

For all rear structures with jacquard According to the invention it is possible to knit the sides of the placed jacquard knitting area according to the intarsia Abbin structure. This is the case with the invention Device preferably provided the intarsia rope to let run run optionally, whereby again the poss the binding position and the type of binding elements is selectable.

For the embodiment of the device according to the invention, where the jacquard knitting area is not in the basic knitted fabric is placed, it is advantageous to the back of the jacquard Optionally not to knit knitted fabrics, d. H. the backside has floating threads, or as stripes, twill, nets with ver different network structures or as a cross tube. Here is under a striped back of the Jacquard-Ge stricks to understand a structure that comes about comes that the color threads present in the pattern go down on everyone teren needle are knitted so that when looking at the Knitted fabric on the back has a uniform stripe structure results.

According to a further advantageous embodiment of the invention dung takes place optionally and in the desired manner before the start of the jacquard knitting process a preparation of the back Weave structure and / or at the end of the jacquard knitting process a completion of the backside binding structure, for example in the form that one or more of the jacquard knit area of adjacent stitches of the basic knitted fabric with the Patterned jacquard thread or in these stitches of the Basic knitted handle of the jacquard area thread  will. It is also advantageous if the direction of the Thread supply or discharge to the color sample and / or the for the and removal of the thread of the color pattern provided binding structure is selectable.

With the following in structure and functions written facility can, based on input information such as outline patterns, weave patterns and color patterns including Color pattern definitions (jacquard, intarsia, transitions) Control program for a universal knitting machine or a special knitting machine of a predetermined machine type to be created. The input information is usually not yet in such a way that they can easily be knitted current control program can be calculated. For example as two already knitable weave patterns, z. B. from an appropriate library as part of the facility retrieved and arranged next to each other in the row direction Creation of a corresponding stitch product, see this connection usually brings with it adjustment problems because the corresponding courses of both bindings each together during a run of the castle of the Knitting machine are to be produced. Are in the same Chen row incompatible operations such. B. opposing transfer operations or transfer operations different cape distance, that's the knitting machine unable to perform these operations during a single to perform lock strokes. With the help of the invention Setup is made from the input, which is not itself knit formation a knit control program for the knitting machine machine derived, for which the facility a corresponding Matching unit, which is checking for knitting contract and the incompatibility is found a correction to correct the incompatibility or makes an error message if the Intolerance cannot be corrected by her.  

Insofar as we speak of knitting machines in this context general flat knitting machines and Circular knitting machines as well as flat or circular knitting machines can be understood that with pointed needles, latch needles or the like are equipped.

Under the term knitted fabric is therefore both a Knitted fabrics, as well as a knitted fabric (English: warp knitted fabrics) can be understood, each with Thread running in the direction of the course, d. H. across the goods-Ab direction of travel.

The general structure of the device designated 10 for developing a control program is shown in FIG. 1. The input of the required information can be done in many ways, such as by means of data line 12 , using magnetic storage means such as. B. diskette 14 , or input keyboard 16 . An input unit 18 indicated by a broken line has the required interfaces. It can also be provided with a series of data memories for the temporary storage of the information entered, but also for the provision of appropriate libraries. In Fig. 1 one of the memory 20 for outline patterns, a memory 22 for binding pattern, and a memory 24 for color patterns is indicated.

If, for example, a knitted fabric 25 shown in FIG. 2 is to be produced as a knitted product, appropriate control programs are developed for the chest, back and sleeves. The entry of the information for the front part is shown in FIG. 2. Here, the information about the outline, binding and color is entered separately and only when the final outline, the final binding structure and the final color pattern have been overlaid on top of each other. The outline is expediently already considered in the course of the development of the binding structure and the color pattern in order to maintain an arrangement limitation.

In Fig. 2 with a broken outline, a subunit 18 a is indicated for the input and processing of the outline information, with 18 b a subunit for the input and processing of the binding information and with 18 c a subunit for the input and processing of the color information. The latter also includes information about the practical execution of the color pattern, optionally as jacquard or intarsia, if necessary specifying the type of transition desired, e.g. B. Overlap width and definition of the back. In order to be able to check the input information and, if appropriate, corresponding corrections, a graphics unit 26 is provided which is connected to the input unit 78 and which is in turn connected to an optical display unit in the form of one or more screens 29 . The adaptation of the binding pattern is carried out using the adaptation unit already mentioned and designated 28 in FIG. 1, which is connected to the graphics unit 26 for interactive pattern adaptation. Any correction suggestions of the adaptation unit 28 or error messages are returned to the graphics unit 26 , which causes the corrected binding arrangement to be displayed on the screen 28 , or the original binding arrangement together with the error message. The operator can then release or perform a manual correction. In the first case, the adaptation unit 28 passes the determined binding arrangement on to the overlay unit 30 also indicated in FIG. 1. After manual correction, the adaptation unit again performs a check for knitting compatibility, and if necessary, transmits a new correction proposal back to the graphics unit.

In the superimposition unit 30 , as already explained, the information about the binding structure and the color pattern are superimposed on one another, where necessary, corrections for mutual adaptation are again carried out in a dialog process with the operator.

Only when there is a knitable overall arrangement in terms of binding, color and / or outline in the overlay unit is the information collected from the overlay unit forwarded to a control program computing unit 32 indicated by a dashed line on the operator's command. This consists at least of a first subunit 34 for calculating a general program that is independent of the knitting machine type. This control program is based on a universal knitting machine which has the essential structural features common to all conventional knitting machines. In the case of flat knitting machines, needle beds that can be displaced as a whole are generally provided. The universal control program will therefore contain commands that aim to move the two needle beds relative to each other in the predetermined direction. The type of needle bed movement differs from type to type; For example, only the front needle bed is movable in one type, only the rear needle bed in another type and both in a third type. It is therefore still necessary to implement the universal control program in a machine type-specific control program, for which purpose the corresponding knitting machines are to be provided with an appropriate compiler. The illustrated device 10 may be provided with a second sub-unit 36 , which is connected to the first sub-unit 34 , for the optional generation of corresponding machine-type-specific sub-programs. Upon corresponding command from the operator, the second subunit 36 calculates the corresponding control program for the desired type of knitting machine. The determined universal control program or machine type-specific control program can then be in the usual manner, for example via data line 38 or magnetic storage means, such as. B. disk 40 , the relevant knitting machine 42 are supplied. For those knitting machines that still work for jacquard cartridges and control command lists, a list and cartridge editor 44 can be provided, which is loaded with the machine type-specific control program and which contains the control command sequences of the desired type and Way in list form, cartridge form or, if provided, stored on disk 46 for appropriate transmission to the knitting machine 42nd

The graphics unit 26 is connected to the storage of the pattern information with a memory 26 a, which also optionally allows the retrieval of the original or the last corrected binding arrangement.

In addition, the graphics unit offers the option of alternating between different types of display. And that in the representation of the overall arrangement or parts thereof. This is indicated in Fig. 3, in which one can see ne the representation of the outline 27 and the color pattern (strawberries) 50 altogether 3 different types of representation for the weave pattern "braid". At the bottom, a screen display 52 is indicated in accordance with the thread travel display mode; a screen display 54 follows in accordance with a symbol display type and finally at the top a screen display 56 in a mesh display type.

The basic type of representation is the thread path representation type, since in this way the thread path and the operations to be used are recognizable with each lock stroke. The elements used in this illustration result from FIG. 7a. The following standard elements are shown in the top line of the image from left to right: stitch 1 ; short stitch 3 ; Handle 5 ; short handle 7 ; Floating 9 , each based on the corresponding needle. These elements are the binding elements, which are to be arranged next to each other in the so-called binding row or binding rows.

The following modification elements from left to right are shown in the lower line: Throwing 11 ; Capes 13 ; Ma share parts 15 ; Needle bed offset to the right 17 ; Needle bed offset to the left 17 . Except for the needle bed offset symbol, these modification elements are by no means to be arranged in rows or rows of ties, but in separate rows or rows of changes. In connection with this description rows are called the rows parallel to stitch rows direction of a substructure of the overall arrangement, z. B. a weave pattern. The corresponding sequence of elements of the next larger structure, namely the so-called binding arrangement, which is parallel to the direction of the stitch row, on the other hand, is designated as a line from the two matching binding patterns, for example. If two binding patterns are placed next to each other, their rows are in turn part of the corresponding rows in the binding arrangement.

Fig. 4 shows an example of the thread running representation of a so-called 2 × 3 braid. In the bottom row you can see a row of ties consisting of the elements right stitch / float / right stitch / float / right stitch / float / float / float / float / float / float / float / float / float / left stitch. This is followed by a modification series consisting of the elements move to the right (in the direction of space) / move to the right / move to the right / no element / no element / no element / no element.

The following row of bonds is followed by a total of 5 rows of modifications. These must be processed before the third third row of bonds in FIG. 4 is processed.

The same binding structure is shown in Fig. 5 in the symbol representation. It is more compact since each row or row also corresponds to a stitch row of the finished product. However, the full information about the type of stitch formation cannot be taken from this type of representation. In order not to make the representation too confusing, only as many symbols are provided as there are binding elements with and without a single subsequent conversion operation. A corresponding conversion table for the total of 72 symbols is shown in FIG. 7b. In the case of a modification operation that exceeds the area of a pair of needles, a special character "x" is superimposed, where is indicated in Fig. 7b below using an example with a necking operation over several pairs of needles.

In the stitch display mode, stitch patterns are shown instead of the symbols, which represent the actual stitch shape in the finished stitch product as realistically as possible. To this end, digitized excerpts of the knitted fabric are stored in a corresponding library. Fig. 6a shows, for example, the symbol of a right stitch and Fig. 6b the associated stitch element of a stitch image of the right stitch. The display 56 according to FIG. 3 is composed of a large number of corresponding stitch elements and gives a realistic image of the product to be knitted.

The basic procedure of the device 10 for interactive program development can be found in the flow chart according to FIG. 16. A start block 60 is followed by a block 62 for entering and / or placing the desired binding, color and / or outline patterns within the overall arrangement on the basis of corresponding input information from the operator. The binding patterns can originate from a corresponding library or, under certain circumstances, can also have been entered point by point. In block 64 , the selected type of display is activated by the graphics unit 26 on the basis of corresponding inputs. Based on a subsequent block 66, this causes the binding arrangement to be shown on the screen.

In a subsequent decision block 68 , it is checked whether the operator has entered the command that an immediate manual correction should be carried out. If this is the case, the device 10 reads in the corresponding correction inputs in block 70 and accordingly changes the stored binding arrangement to be processed in the following. If no manual correction is desired, block 70 is skipped.

Subroutines are then processed, the one Knitting compatibility test of the binding arrangement by lead and corrective measures in the event of an identified incompatibility arrange the binding arrangement.

First, a subroutine 72 is called, which ensures that the binding series of the entered binding patterns each connect to one another, as is demonstrated in FIGS . 8 and 9. This subroutine 72 is explained in more detail in FIG. 17. This is followed by a subroutine 74 , which reveals the fixation of crossings in rows of beds with bedding offset and which tries to achieve a correction by moving one of the two binding patterns as a whole relative to the other binding pattern. The program 74 is explained in more detail in FIG. 18.

In the course of subroutine 74 , subroutine 72 is run through again.

In a subsequent subroutine 76 , Abwandlungszei len are divided with reassignment processes with different distances to correct a corresponding knitting incompatibility. The subroutine 76 is explained in more detail in FIG. 19; the associated thread travel representation is shown in FIG. 11.

In a subsequent subroutine 78 , a modification of lines of modification with transfer processes with different directions is carried out in order to remedy a corresponding knitting incompatibility. This subroutine is explained in more detail in FIG. 20; Fig. 12 shows the associated Fadenlaufdar position.

In a subsequent subroutine 80 , transfer processes over greater distances are checked for feasibility and, if possible, appropriate corrections are made to correct the intolerance to knitting. This subroutine is explained in more detail in FIG. 21; Fadenlaufdar the positions according to Fig. 15 serve for additional explanation.

In a subsequent block 82 , the result is displayed on the screen. It is then checked in decision block 84 whether the operator now wants to make a manual correction or not. In the first case, the program jumps back into the main program branch between blocks 68 and 70 . Then, after manual correction, read in block 70 , the knitability of the binding pattern is checked again.

If no manual correction is to be made in the representation of the binding arrangement present on the screen 82 , a decision is made in a decision step 86 as to whether or not a color pattern is superimposed on the basic knitted fabric. The color pattern can, for example, be entered beforehand according to the input block 62 and its placement can be determined. In this decision step 86, however, the user also has the option of entering and / or placing his color pattern or reading in a corresponding color pattern stored on a storage medium which contains no knitting technical information in its colors. This is done in the color pattern overlay block 87 .

A subroutine 88 then runs, with which the type of knitting and further parameters for the color pattern overlay are determined or designed. Subroutine 88 is shown in further detail in FIG. 22 and is explained in detail in connection therewith.

After passing through the subroutine 88 , a decision is made in a decision step 89 as to whether the color pattern is matched to the binding pattern, ie whether the binding series of the color and binding pattern have been checked for compatibility and / or incompatibilities have been corrected. If this is not the case, the program jumps back to program block 72 and runs through the program steps described above. In the event that it is determined in decision step 89 that such a color binding pattern adjustment has been carried out, the knitting pattern is displayed on the screen according to block 90 and in decision step 91 it is queried whether a manual correction should be carried out. If this is the case, the program returns to program block 70 for manual correction. Otherwise, the program is further processed by querying in a further decision block 92 whether an outline pattern is superimposed on the binding and / or color pattern.

If the overlap of a basic knit with a color pattern is denied in decision section 86 , the program jumps to decision step 92 for the query as to whether an outline pattern overlay should take place.

If the basic knit and / or the color patterns superimposed one Umrißmu art, takes place in program step 93 delay this Überla, is again being resorted to have been scanned in the program block 62 related information, or the operator of an inventive device will be prompted to enter the contour pattern.

After the outline pattern has been entered, a decision is now made in decision step 94 in accordance with decision step 89 for the color pattern for the outline pattern as to whether the binding and / or color pattern has been adapted to the outline pattern or not. If this is not the case, the program jumps back to program block 72 . However, if such an adjustment has already been carried out, the binding structure now present is displayed on the screen in accordance with program step 95 and the user is asked to decide in accordance with program step 96 whether a manual correction should be carried out or not. If so, the program jumps back to program step 70 for making manual corrections.

If no manual correction can be performed, a universal STEU in a subsequent program step 97 is created erprogramm which can be outputted selectively, which is indicated by an output block 98th This universal control program is knitting machine-independent and can therefore be used for a variety of knitting machines, with the help of a corresponding Com pilers, the z. B. can be integrated in the respective knitting machine, a machine type-specific control program is created. In the device 10 , the previously mentioned second sub-unit 36 offers the possibility of creating a specific control program for the common types of knitting machine, which is indicated by a block 99 . The output then takes place again (from output block 100 ). The program has now run through completely (end block 101 ).

A typical starting situation is shown in FIG . A weave pattern designated with B1 ("Aran") is to be knitted together with a second weave pattern B2 ("braid"), the two weave patterns following one another in the direction of the course MR. The wales direction MS, which corresponds to the direction of goods withdrawal, is also shown in Fig. 8.

Each of the two binding patterns B1, B2 is for itself knitting bar, but not their combination in the binding assembly of Figure 8. This is in particular the fact that each parallel to the direction MR line Z, the other by the two gegenein staggered rows of needles 100 a of the front needle bed or the needles 100 b of the rear needle bed is symbolized, and which are shown continuously in Fig. 8 from left to right, each to be processed by one run of the lock of the knitting machine. It is impossible with a series of bonds, e.g. B. in 102 of the left weave pattern B1, and then continue with a pure modification row 104 of the weave pattern B2. So there must be all lines Z either consist only of binding elements or consist only of modification elements.

In the subroutine 72 according to FIG. 17, the adaptation unit 28 ensures an automatic mutual alignment of the binding rows and modification rows of the two binding patterns B1 and B2. In an output block 110 , the first line Z1 of the binding arrangement is selected. In a subsequent decision block 112 , it is checked whether there is a row of bonds in the binding pattern B1 in the current row Z1, which is the case in the example in FIG. 8 in row Z1. The program therefore continues in a decision block 114 , which checks whether there is also a binding row of the same color of the binding pattern B2 in the current line. This is the case at line Z1 in FIG. 8, so that the program proceeds to a decision block 116 . Here it is checked whether all rows of B1 or B2 have been processed. This is not the case in our example, so that the program proceeds to block 118 , which advances to the next line (Z2).

The program then jumps back into the main branch between blocks 110 and 112 . For our example, the answer in decision block 112 is no, since the second bond row of B1 is a modification row with 4 transfer elements 120 . The program therefore continues in a decision block 122 , in which a query is made as to whether there is a binding row in B2. This is the case according to FIG. 8. In a subsequent block 124 , an empty line is inserted in front of the current line Z2 in the binding arrangement, with the result that both binding patterns B1 and B2 are raised by one line to their lowest binding row. Then, in a block 126, the raised rows of B1 are set back one row so that the row of modifications having the four modification elements 120 replaces the corresponding empty elements of the inserted empty line.

The result of this operation can be seen in FIG . The bottom, unchanged line Z1 is followed by the inserted line Z1.1, which only has the 4 transfer elements 120 .

It is then checked in decision block 116 whether one of the patterns has already been processed; if this is not yet the case, the program jumps back between blocks 110 and 112 via the line advance (block 108 ). If it is determined during the program flow in decision block 114 that there is no binding row in B2, although it was determined in the previous block 112 that there is a binding row in B1, the subsequent blocks 130 and 132 act similarly to blocks 124 and 126 for the fact that the binding pattern B2 having the binding row is raised in the result until, after the required number of program runs, this binding row is opposite one binding row of the other binding pattern B1.

The result is the corrected binding arrangement according to FIG. 9, each with continuous binding lines and modification lines.

According to FIG. 10, a knitting problem can occur when two weave patterns are arranged side by side if a weave row BR1, e.g. B. the weave pattern B1 continues in a weave row BR2 of the other weave pattern B2 with an offset, for example, of the rear needle bed to the right, as indicated by the corresponding modification element 134 . The two weave patterns B1 and B2 can each be knitted per se, but not the combinations, as shown in FIG. 10b. When performing the offset he gives a so-called mesh crossing within the area marked with a circle A, which is fixed by the subsequent insertion of the thread. This results in an undesired change in the binding structure of the finished product.

Subroutine 74 according to FIG. 18 automatically tries to avoid such crossings. In an initial block 140 , a count parameter n is set to 0. In a subsequent block 142 , the repeat length r of both the binding pattern B1 and the binding pattern B2 is determined. This repeat length indicates the period length of the periodic pattern B1 or B2 in the direction MS according to FIG. 8. In a subsequent block 144 , the distance between the top line of the binding arrangement composed of B1 and B2 and the end to be knitted last of the end of the overall arrangement B-total (defined by the outline read in block 63 ) is determined.

A decision block 146 checks whether a bed offset occurs in the current row, which is determined by the count index n. If this is not the case, then subroutine 74 has been successfully completed. If, however, there is a binding row with bed offset in the row in question, a decision block 148 is then used to check whether an intersection occurs in the other binding row (B1 according to FIG. 10) due to this bed offset. If this is not the case, the program has been successfully completed. If, however, an intersection occurs, a decision unit 50 checks whether the distance to the end of B determined in block 144 is smaller than the larger value of the repeats rB1 and rB2 determined in block 142 . If the distance is greater than or equal to the maximum value, ie there is sufficient displacement space, then in a subsequent block 152 a basic formation line is inserted in front of the first binding line of the composite binding arrangement for the corresponding displacement by one line upwards.

Subsequently, the binding pattern B2 is reset together by one line, so that the mutually incompatible binding lines BR1 and BR2 according to FIG. 10 no longer follow one another. Then the binding series and modification series of the two binding patterns B1 and B2 must be aligned again, which is caused by a block 156 which calls the subroutine 72 . After it has been processed, a decision block 158 checks whether the program loop of subroutine 74 has been run through so often that the resulting shift corresponds to the maximum value of the two reports rB1, rB2. If this is not the case, the loop is run through again in a block 160 after the counting index n has been increased.

If, on the other hand, it is determined in block 150 that the distance to the end of B-total is smaller than the maximum value for the repeats, a shift to the beginning of the knitting is made by inserting a basic binding line after the last line of the binding arrangement (block 162 ) with a corresponding shift of all rows of the composite binding arrangement towards the beginning of the overall arrangement. Then one of the two binding patterns, in particular B2, is advanced by one line (block 164 ).

If, after carrying out the maximum shift corresponding to the maximum of the two reports, intersection still occurs, a corresponding error message is initiated via block 166 .

The subroutine 76 according to FIG. 19 checks the binding arrangement for whether transfer operations with different transfer distances are provided in a line. Such a line is shown in Fig. 11a with a first conversion element "capes" 170 a, which is followed by a second cap element "capes" 170 b. The cape distance (distance between the starting needle and the target needle) is approximately twice as large in the modification element 170 b as in the modification element 170 a. On the generally customary knitting machines, it is not possible to carry out transfer operations with different transfer distances and accordingly different needle bed misalignments in a single lock stroke. The adapter unit now produces a knitability by moving the two binding patterns against each other in such a way that both modification elements are in different lines.

The subroutine 76 of Fig. 19 begins with an initial block 172, in which the first Abwandlungszeile Gesamtanord the voltage from the two binding patterns B1 and B2 is selected. In the subsequent decision block 174 , a check is carried out to determine whether transfer processes with different distances occur in the current line. If this is the case, an empty line is inserted in front of the current line in a subsequent block 176 .

In the subsequent decision block 178 , it is checked whether the larger transfer process is provided in B1. If this is not the case according to FIG. 11a, then in a block 180 the rows following B2 that are inserted after the inserted row are reset by one row. The program then continues in a decision block 182 , in which it is checked whether all modification lines of the binding arrangement have been processed.

If it is determined in decision block 174 that no reassignment processes with different distances occur in the relevant line, then a decision is also made immediately to decision block 182 . If it is determined in decision block 178 that the major reassignment process is in B1, the program proceeds to block 184 in which the rows of B1 following the inserted line are reset by one row. The program then proceeds to decision block 182 and from there via a line advance block 185 back to the beginning between blocks 172 and 174 .

If all modification lines have been processed in this way, the subroutine is ended. Because B1 or B2 is reset, depending on where the larger transfer process is located (block 178 ), it is automatically sufficient that the line with the larger transfer process always precedes the line with the smaller transfer process after splitting. This is advantageous in terms of knitting technology.

Furthermore, it must be avoided that transfer operations in the opposite direction have to be carried out in a modification line. In Fig. 12a, such a case is shown with a modification element "transfer" 184 a from left to right, which is followed by a modification element "transfer" 184 b in the opposite direction. Here, too, this non-knitable succession of modification elements was created by joining together the weave patterns B1 and B2, which are actually knit. The adaptation unit 28 in turn separates the initially combined modification series of B1 and B2, as shown in FIG. 12b.

Referring to FIG. 20 of the program 78 Unterpro is properly selected, the respective first Abwandlungszeile the Bindungsan in an initial block 186. In the subsequent decision block 188 , a check is carried out for the current line in each case to determine whether there are any current transfer processes. If this is the case, an empty line is inserted in front of the current line in a subsequent block 190 and then in the subsequent decision block 192 it is checked whether the transfer process "right to left" ( 184 b in FIG. 12) is provided in the binding pattern B1. If this is not the case, as in FIG. 12a, the rows of B2 following the inserted line are reset by one row in a block 194 (with the result corresponding to FIG. 12b).

If, on the other hand, the said transfer process "right to left" is actually in B1, the rows of B1 following the inserted empty line are reset by one row in a block 196 . Following blocks 194 and 196 , a decision block 198 checks whether all modification lines of the pattern arrangement have already been processed. If this is not yet the case, the program returns to the beginning of the program between blocks 186 and 188 via a line advance block 200 . If all modification lines have been processed, subroutine 78 is ended.

A further knitting incompatibility can occur according to FIG. 13 if, on a line with both right and left binding elements, ie with binding elements that are formed on both rows of needles, a line with a conversion element "transfer" follows, and the transfer process due to the unfavorable direction and Umhangentfer removal can not be carried out, otherwise the thread breaks at the needle bed offset in the transition area between the two needle beds. The modification element "transferring" 210 indicated in line Z6 in FIG. 13 is intended to ensure that the stitch 212 of the rear row of needles is transferred to a needle 214 of the front row of needles. For this purpose, the two needle beds must be shifted far apart, for example the rear needle bed to the left. Here, however, the transition section 216 of the thread to the right of the stitch 212 is unduly stressed. The other transition section 218 is not overstressed in this transfer operation since it is not stretched at the beginning of the movement, but is pushed together and is not yet subjected to tension at the end of the needle bed displacement (by two needle bed grids).

The situation shown in Fig. 13, for example, from the situa tion of FIG. 14a have been formed. The binding structure shown here can be knitted per se since the problematic transfer operation (modification element 210 ) is preceded by another transfer operation, namely a modification element "transfer" 220 , which ensures that all stitches are formed on the same row of needles. Since both the direction and the cape distance of the two modification elements 210 and 220 are different from one another, the corresponding subroutines 76 and 78, already described, provide for an arrangement of the modification elements in different lines, as shown in FIG. 14b such that the modification element comes with the larger cape distance first; then, however, the undesirable situation according to FIG. 13 is given, since 210 stitches are arranged on both rows of needles when the conversion element is implemented.

According to the subroutine 80 shown in FIG. 21, starting from the situation according to FIG. 14b, the lines are interchanged in order to obtain the knitable situation according to FIG. 14c, in which the modification element reassignment 220 is carried out first, with the result that then all stitches are on the back row of needles. The Abwandlungse element capes 210 can then be easily implemented.

In a start block 230 of the subroutine 80 , the lowest binding line of the binding arrangement is selected. In the following decision block 232 it is checked whether there are both left and right education elements. If this is the case, it is checked in block 234 below whether a modification line with a reassignment process follows the current binding line. If this is the case, the maximum transfer distance U _max in the direction of the transfer process is calculated in a subsequent block 236 , i.e. all connecting sections 216 , 218 of the thread between the two needle beds are checked to see whether they are subjected to tension at the start of the transfer process (the generally corresponds to the cape distance zero) or initially compressed, in which case the maximum cape distance is approximately twice the length of the connecting section. The maximum necking distance is of course the smallest allowed necking distance in the said necking direction of all connecting sections.

In a subsequent decision block 238 , it is checked whether the actual reassignment distance corresponding to the ascertained reassignment process is greater than U _max . If this is the case, there is a knitting intolerance. In the following, an attempt is then made to remedy the intolerance to knitting. For this purpose, a check is made in a subsequent block 240 as to whether it is possible to swap the modification line containing the reassignment process with a subsequent modification line. If this is the case, then in a subsequent block 242, both modification lines are exchanged, with the program returning between blocks 234 and 236 for the subsequent rechecking of the maximum transfer distance, taking into account the modification lines preceding the actual transfer process, including the interchanged modification line.

If it is determined in block 240 that an exchange with the following modification line is not possible, for example because the next binding line follows immediately, in a subsequent block 244 it is checked whether an exchange with a previous modification line is possible with the hope that that knitting tolerance is then given. If there is a possibility of swapping, the swapping is carried out in block 242 and the program branches again, starting with blocks 236 , 238 .

If an exchange with the preceding modification line is not possible, a check is made in block 246 as to whether the reassignment process starts from a left element. If this is the case, it is checked in a subsequent block 248 whether it is possible to move the right elements to the left, since this presupposes that the new space for the right elements is not already occupied by a left element. If the possibility of transferring is given, then in a subsequent conversion line causing block 250 in these transfer operations is inserted before the relevant modification line with the problematic transfer process. So that the basic binding structure does not change, an inverse modification line is created in block 252 following the modification line with the problematic reassignment process, so that the program can then proceed to further processing the next binding lines.

A decision block 254 asks whether all the binding lines have already been processed. If this is not the case, then a block 256 is used to advance to the next binding line between the starting blocks 230 and 232 <10895 00070 552 001000280000000200012000285911078400040 0002004329875 00004 10776 / BOL <for re-running the program until finally all binding lines have been processed. If it is determined during the program flow in block 232 that either only right or only left binding elements are present, the program jumps between blocks 252 and 254. This also applies in the event that it is determined in block 134 that the current one Binding line is not followed by a modification line with a reassignment process. This also applies if it is determined in block 238 that the distance from the cape is not greater than the U _max . If it is determined in block 246 that the reassignment process starts from a right element, the program proceeds to a decision block 258 which checks whether it is possible to reassign all left elements to the right. If this is the case, then in the blocks 250 and 252, a modification line carrying out this transfer operation is issued before the modification line having the problematic transfer process, and a corresponding inverse modification line is readjusted. 15 shows the effect of these additional modification lines. In Fig. 15a, the modification line 27 with a conversion element 266 for transferring from the left row of needles to the right row of needles, namely by three raster distances to the left. The preceding line Z6 is a binding line with predominantly left-hand stitches 260, but also an isolated right-hand stitch 262. The connecting section 264 would be stretched too much when the modification element "transferring" 266 was carried out after initial compression, since the distance to the neck would exceed twice the section length . The subroutine 80 now ensures with its steps 246 ff that before the line Z7 a line Z6 'is inserted with a conversion element "reassign" 268, which ensures that the lonely right stitch 262 is reassigned to a free needle 265 of the rear row of needles is so that the reassignment operation according to line Z7 can then be carried out. The line Z7 'inserted after the line Z7' reverses the reassignment operation according to line 26 ', for which purpose it has a correspondingly oppositely directed conversion element "reassignment" 270 in the same place as in the Z6'. The subroutine 88 already mentioned in FIG. 16 for assigning the type of knitting is explained below with reference to FIG. 22. After the desired color pattern has been entered in accordance with program step 78 indicated in FIG. 16, the type of knitting which is to be assigned to the color pattern is queried after program point N in a program block 300. The user receives a corresponding query, for example, on the screen 29, or can call up such a query on the screen. For the user, there is a choice between an intarsia knitting process 301, a jacquard knitting course 302 or a so-called transparent knitting process 303. When the intarsia knitting process 301 is selected, the device 10 enables the user to choose the type of tying and to select the tying position step by step 302 and the type of binding elements 303 for the binding, or in reverse order. As mentioned earlier, the type of illustration relates to the way in which the intarsia color threads are tied in the intarsia colors and in the transition from the intarsia knitting area to the basic knitting area and vice versa with the neighboring threads . For the position of the tying (program step 302), an automatic arrangement of the position of the tying or a selectable position of the handles, for example, -2, - 1 or -4 needles or stitches in the basic knitted fabric is possible. With regard to the choice of the binding elements, long or short handles or meshes can preferably be selected. The decision "no setting" is also possible. The adaptation of the binding types in accordance with the selected parameters with regard to the imaging position and the binding elements is carried out in accordance with program steps 302 and 303 after returning to program point O (see FIG. 16) by the adaptation unit, if no adaptation has yet been carried out, by moving to the program step 72 is returned. If, on the other hand, the type of jacquard knitting is selected by the operator in accordance with program step 302, then, in accordance with program step 305, the operator is then asked, for example by means of a screen query, to choose whether the jacquard knitting area is placed or not, which is shown in FIG gram blocks 306 and 307 is indicated. If a placed jacquard knitting area is selected, in a further query step 308 it is possible for the user to choose between a network structure and a cross tube structure (cf. program blocks 309 and 310) for the back of the knitted fabric by means of an additional screen prompt. In the event that a network structure 309 has been selected, a further additional choice according to decision step 311 for twisted networks or for the use of the basic thread within the placed jacquard area (program blocks 312 or 313) is possible. The selection is in turn prepared for the user by a corresponding window on the screen. After the execution of the program steps mentioned, a decision is made in a decision step 314 as to whether or not the sides of the placed jacquard knitting area are to be carried out by intarsia knitting. If this is the case, the program jumps to program step 302 for the selection of the type of tying or its implementation and runs through program steps 302 and 303 for the intarsia knitting type, as has already been described above. If, when deciding whether to place or not to place the jacquard knitting area (see program block 305), it was decided that the jacquard knitting area should not be placed, that is to say should extend over the entire width of the knitted fabric (see program step 307), the user has to do so he device according to the invention the possibility to choose between different back structures of the knitted jacquard according to decision block 315. The user is offered corresponding alternatives for selection on the screen. These can be, among other things: no knitting on the back or laying flotation threads on the back (316), striped structure (317), twill (318), net (319) of various structures, or knitting cross tube (320). After the program has processed the corresponding program block depending on the selected back structure of the jacquard knitted fabric, the subroutine 88 in this case returns to the main program at program point O. In the exemplary embodiment shown for the device according to the invention, it is possible with decision block 300 (see FIG. 22) to select the so-called transparent knitting type (block 303) in addition to the intarsia and jacquard type, so that - like has already been explained - even if the basic pattern is a rectangle to overlay the color pattern, parts of this color pattern can be knitted as a basic structure, i.e. transparent with regard to the color pattern. After passing through this subroutine block 303 for transparent knitting, the subroutine 88 also jumps back to the main program at program point O in this case. The invention, as well as further features, refinements and advantages of the invention have been described with reference to the illustrated embodiments. The person skilled in the art, however, numerous modifications, refinements and modifications are possible without thereby leaving the inventive idea. For example, the adaptation unit 28 of the device 10 according to the invention can be designed only for certain processes, for example only for the binding pattern, or only for the color or outline pattern adaptation, if this appears advantageous or sufficient for certain applications. Various options for contour pattern adjustment are also possible. It is also particularly advantageous that when adapting the color pattern to the basic knitted fabric, in particular in the case of jacquard knitting, preparation of the rear side binding structure or, at the end of the process, completion of the rear side binding structure takes place before the start of the jacquard knitting process. It is also advantageous if the direction of the thread supply or removal to the color pattern and the binding structure provided for the supply or removal of the thread of the color pattern can be selected. All these possibilities, with which the user can take a flow on the knitting process via the adaptation unit 28 of the device 10 according to the invention, is preferably structured by corresponding query windows which the user can call up or reject. It is particularly advantageous in the device according to the invention that through the possibility of displaying the knitted fabric in various display types, the user gradually receives the progress of the adaptation and correction process and, depending on it, the structure or the binding pattern manually as required can change. Even in the case of a manual change, it is then ensured that the resulting incompatibilities in the knitting process are recognized by the unit according to the invention, so that if the adaptation unit cannot carry out the correction itself, it detects an error message and a manual correction can be carried out by the operator in a targeted manner is.
