Abstract

Equipment for the development of a knitting machine control programme comprises an input unit (16) for entering data groups, esp. shape, colour and structure, to define the knitted item, graphics unit (20) and screen (21) for data reproduction and a control programme generator (60) for the prodn. of all knitting machine (64) element programmes relating to the item. A programme development unit (22, 24, 26, 28, 30) is allotted to each data group, from which is produced an instruction sequence for each required machine (64) element in at least one processing step where the graphics unit plays a part at least. During at least part of the process, each development unit selectively modifies the results in the light of amendments from the input unit and reproduces these in the form of altered instruction sequences for the generator which produces a new control programme from all the development units.

Description

The present invention relates to a device for Development of a control program for a knitting or Knitting machine for producing a knitted fabric, full

• - An input unit for data entry of several das Input data groups defining mesh product especially of shape, color and structure data,
• - A graphics unit with a display unit, in particular Screen for graphical representation of the stitch product-defining input data,
• - A control program generation unit for generation a machine-dependent or machine-independent Control program for various stitches Contributing or mesh-influencing machine elements the knitting or knitting machine.

In the case of the knitting or warp knitting machines in question flat knitting machines, especially two Needle beds, circular knitting machines, knitting machines nen, especially around also known as Cotton machines Flat warp knitting machines or warp knitting machines (including rustling machines) act with tips needles, reed needles, tubular needles, sliding needles or Like .. are provided. For knitting machines or Kulier knitting machines is the thread course across the manufacturing direction of the knitted fabric. According to the German language In this case we need a single-thread knitted fabric spoken, provided it is made on a knitting machine or by a single-thread knitted fabric, if one Knitting machine has been used. With a chain The knitting machine runs the threads of this warp knitting machine-made knit, the warp knit according to German language usage, essentially parallel to  Production direction of the knitted fabric. Warp knitted fabrics usually have several thread systems, so that from a multi-thread knitted fabric can be spoken.

Facilities of the type mentioned are also under known as the sample plant. The development of the Control program for the knitting or knitting machine by means of Accordingly, the sample system can also be used as a sample development.

A facility or sample system of the beginning ten type is known from DE 43 29 875 A1. At this The patterning facility is the first to be created from the binding structure data a knitable design of the knitted fabric developed with definition of a specific thread course. An intermediate adjustment step serves to eliminate binding pattern incompatibilities. This design will then Color pattern data is again overlaid with matching intermediate step to create a also include the color swatch the knitable design. Finally there will be Outline pattern overlaid. However, the end are overlaid valid outline, binding structure and color sample data, however, the outline is expediently already in Course of the previous one, in the case of the color pattern the graphic design limited development of the Binding structure and the color pattern can be superimposed, to get a layout limit.

Before and after the overlays and before generating the Control program there is a possibility to correct against adjustment in the dialog procedure using the Graphics unit, each of the last determined knit shows clear design. A change or correction, for example the color pattern or a binding structure, takes place in this sample system only within the the overlay unit generated result data that the  Thread course depending on the final shape, Specify color and structure data. A change in the thread course due to necessary corrections does not work back to the underlying input data. One of the such a retroactive effect would also be very difficult to achieve or is even impossible because the underlying shape, Color and structure data to generate the result data to some extent are mixed together so that a certain special thread course individual input data cannot be assigned or can only be assigned with great difficulty. So can e.g. B. in a single-thread knitted fabric, a looped stitch to a jacquard pattern or a structure pattern (e.g. Braid).

There are connections for the user of the sample system between the input data initially entered and the one with the known sample system in a possibly quite long interactive design process determined thread course difficult to recognize or not at all. A subsequent one Correction of the input data such that the overlay immediately gives the determined thread course is practical locked out. It is therefore not possible to develop separating the result of the investment into shares, each one correspond to individual input data groups, in particular form Share, color share and structure share. Would the Ent winder z. B. the structural pattern of a development result combine later with another color sample, see above he has to go through another complete design process that may not lead to exactly the same Structure pattern leads.

The invention has for its object a device of the type mentioned at the beginning with simplified patterning development, especially simplified pattern variations opportunity to create. This task is solved that

• - The input data groups each have a program development unit is assigned for gradual generation of instruction sequences for the respectively assigned dimensions machine elements of the knitting or knitting machine from the Input data of the respective group in at least one Processing stage,
• - The graphics unit for graphical representation of the results Data of at least part of the processing stages is trained,
• - The program development units for optional Modifi cation of the result data of at least part of the ver work stages based on the corresponding change are trained on the input unit, and
• - the program development units for the dissemination of the respective, possibly according to the change input modified instruction sequences to the control program Generation unit for generating the control program the instruction sequences of all program developments units are trained.

Due to the features of the pattern according to the invention plant, the user is able to come from any Instruction sequence resulting from input data group separately develop and the respective development result for to use later pattern variations. It is a one fold correction of the resulting instruction sequences Summary of the developed instruction sequences possible. Since the sequence of instructions relates only to a corresponding one Part of all machine elements is theirs Development for the user well manageable. According to the The user can focus on the invention separately concentrate individual machine elements. Any intolerance opportunities, especially incompatibility can be paid before the final tax Recognize and avoid program generation.  

Another advantage of the sample system according to the invention it is that the pattern easily differs between different ones knitting or knitting machines and especially with certain limitations between a knitting and a Have the knitting machine transferred. The last point is from of particular interest as this creates a knitting machine use for trial creation of a knitwear lets that later in large numbers using a Knitting machine, in particular by means of a cotton machine, can be produced. This results in large knockouts cost savings because the expensive cotton Machines usually have multiple fonts simultaneous work of several identical stitches nits and a trial run therefore one accordingly would result in large production downtimes.

It is of particular advantage if the graphics unit is used for overlaid graphical representation of at least two Information levels is formed by input data a group or processing result data level are formed. This makes it without for the user special efforts possible to get the overall picture to get any time. So you can be detailed work and at the same time take the overall context into account view, whereupon incompatibilities particularly easy can be avoided.

The consideration of the overall context in the de tailored development of the instruction sequences for the Ma machine elements and the avoidance of incompatibilities between different input data groups on input data The instructions based on machine elements are ins especially relieved when the at least two pieces of information mation levels on different input data groups are based. It can therefore be used in the invention separate development of the different groups (e.g.  Color pattern group and structure pattern group) the relative Positioning the pattern elements of the currently adjacent barten group to pattern elements of one or more other groups can be checked and corrected if necessary. For this purpose, it is useful if that in the superposition information levels to be displayed via the input unit are selectable. In this case, the user can choose the select information levels to be displayed so that it only receives the information it needs at the moment, thereby the graphic display remains clear.

It is particularly useful if input data or results Data of the processing stage for the graphic re-creation are symbolized by colors. A symbolization through colors is particularly clear and so makes it easier the user the pattern development.

It is preferred that the superimposed ones are shown selected levels of information layer appears as a color image while the rest Little information levels in the graphical representation at least in certain areas by appropriate gradation of gray or color gradation of the color image or by shades of gray are represented. This allows the user to The most important moment, especially the one in the eye look through data entries or changes highlight the working information level so that the gra phical display remains clear, although the rest Information levels additionally represented and as such be identified. The user is thus through the Wealth of information not confused.

It is useful if the colors of the other informa tion levels gray tones are assigned such that the same Colors are assigned the same gray tones. The user can thus the gray tones in the overlay display slightly  assign the underlying colors. An information association lust by displaying the other levels of information in gray tones is avoided.

The gray tone information preferably takes place during the superimposition mation of various other information levels an ad dition of the gray values of the gray tones. By this measure can overlaps of gray tones or the like Overlay underlying other levels of information are easily recognized, so that in turn none or only one very little loss of information in case of overlap gene occurs. The gray tones can be seen in the graphi still recognize the representation.

It is preferred that a Screen dot corresponds to a stitch of the knitted product and indicates the color and / or the stitch formation. A such assignment is particularly useful because of a stitch of the knit the smallest one of interest development of the pattern.

It is appropriate that in a very small representation Resolution level a raster point a pixel of the graphic unit or screen, while in size display resolution levels one raster point several Pixels. The fact that different resolution stages are provided, the mesh to be developed product at a glance or in detail in the graph representation, possibly overlaid with a representation result data from processing stages be, so that also in this regard a detailed Work taking into account the total connection is possible.

It is preferred that at least one trans Parenzfarbe is selectable and that in the smallest Dar  position resolution level that results from the superposition of the gray tone image resulting in other information levels such as Color tone image is superimposed on the halftone dots of the color sound image in the transparent color through the halftone dots of the Gray tone image are replaced and the remaining halftone dots of the color image are retained. This is si that even in the smallest display level all important information for the user from the selected as well as from the other information levels being represented. Whichever color of the shade image is selected as the transparent color, the Users on various aspects of pattern development focus.

It is useful that in larger display resolution classify themselves from the overlay of the other informa resulting gray tone image with the color image is superimposed on that part of the pixels of each raster point the color of the assigned raster point of the color image and the rest of the pixels of each halftone dot the gray tone of the gray tone image. This results in a simple control of the graphics unit and a quick one Structure of the graphical representation, in particular a faster screen setup. There is no need for the user annoying waiting times. In larger display resolution stages, it is particularly useful that the one and the remaining part of the pixels of a grid point like a checkerboard are arranged. The result is uniform Grayscale gradations of the color image, causing confusion by not due to input or result data shades of gray are avoided.

For simple, especially intuitive work with the It is particularly useful that the data Entries or changes only apply to those of the moment tan on the selected information level  data or on the currently selected information result level of the respective Processing stages impact. Through these measures are Inputs are particularly easy and it becomes incorrect ben avoided. The user always knows which information his level. For certain stages of the Pattern development also makes sense that data input or change entries either changes in several levels of information, possibly at different levels Input groups are based, result. Likewise, it is under certain circumstances it makes sense that a change in a processing stage either a corresponding appropriate change of the result data of a previous one Processing level and, if applicable, the corresponding input data ten results. With these measures, the user has very far-reaching possibilities of intervention with the pattern development, which makes the pattern development strong can be accelerated.

It is advisable that the data entry or change input is alphanumeric and / or graphical. For some input is a graphical input faster, for an alphanumeric entry likes other entries faster his. If both input types are available, the Users who choose him approve, which gives him that Work is made easier. It is preferred that one Storage unit for storing the groups of input data, result data of the processing stages and the Control program is provided. This allows the Input and result data for later use save. It is particularly preferred that stored Groups of input data and result data for further Processing in combination with other input data or Result data optionally read in from the input unit can be. This makes it procedurally special ders simple way that input and result  data from one pattern development for another Pattern development can be used. This will especially the development of a collection of stitches relieved products, because with a collection in space common certain basic elements of design in different Mesh products occur. The same applies to the Ent winding a similar stitch product, e.g. B. a pullover, each for different collections. Certainly differ from collection to collection Basic elements only need to be developed and result in combination with other input data or Result data the stitch product of the respective collection tion.

Although the device according to the invention is a muster development without incompatibilities from the outset easier, at least for less experienced users It makes sense that when generating the instruction sequences in In the event of intolerance, warnings are given. This measure warns the user if he Makes mistakes or has overlooked an intolerance. A correction is therefore before the user Generation of the control program possible.

The control program can be designed for a Cotton machine be, wherein a plurality of input data groups from the Quantity: shape, intarsia, petinet, plating and laying is seen.

When developing a pattern for a cotton machine it makes a lot of sense that the input data of the intarsia Group a color field in a first processing stage division is derived that in a second processing the color fields assigned to individual thread guides and that in a third processing stage parking and positioning instructions for the thread guides  will. The color field division is the basis for the Assignment of thread guides and for the generation of Parking and positioning instructions. It is therefore appropriate ßig that the user already when deriving the color fields of correction and change options. In particular the user gets a look at the results the color field division clearly shows how many color fields in the technical sense his design with regard to the intarsia Designs. Different areas of the same color of the design can nevertheless in the technical sense different color fields.

Before generating the parking and positioning instructions it makes sense to assign the swatches to individual Check thread guide. It may be that depending on the zu regulation for the production of the knitted fabric, here of a knitted fabric, different number of thread guides needed will. By skillful assignment, the user can reduce the number of thread guides required. Is the Number of thread guides required in view of the equipment tion of the available knitting machine too big and the required number can be changed by changing the assignment also not reduce, so the design of the Mesh product by changing the input data of the Intarsia group to be changed.

Only after the design and the color field division stands, in a third processing stage parking and Positioning instructions for the thread guides are generated. For Avoiding intolerance to other measures machine elements, it is particularly useful if the parking and positioning instructions for the thread guides by ent speaking change input corrected according to the invention can be.

From the input data of the Petinet group expediently  the parking, position in some processing stages kidney and deck instructions generated for deck facilities. For the generation of the instructions for the deck equipment it is particularly useful if the input data ten of the form group are taken into account. Also for them Generation of instructions for the thread guide based on the input data of the intarsia group, it makes sense if the input data of the shape group are taken into account.

It is also useful if the Plating group in one processing stage the parking and Positioning instructions are generated by thread guides. The input data of the Lege group makes sense Positioning instructions for Laying devices generated.

Also with regard to the parking and positioning instructions of thread guides based on the input data of the Plating group and with regard to positioning instructions conditions for laying devices on the basis of the input data ten of the Lege group, it is advisable to make corrections opportunities for the user. As with the Correction of parking and positioning instructions for thread leader based on the input data of the intarsia Group as well as in the correction of parking, positioning and deck instructions for deck facilities based the input data of the Petinet group is the respective one Correction within the result data of the respective group pe. The user is therefore always clear within which Group he intervenes. At the same time, with the help of overlay according to the invention always an overview possible. Incompatibilities between machine elements, the different groups are assigned in this way avoid easily. This is also a targeted and thus effective use of the resources of the cotton machine no, e.g. B. the thread guide available on a  possible way.

The control program of the facility or the sample can also be used for a flat knitting machine or a Circular knitting machine can be determined, wherein a plurality of Input data groups from the set Jacquard, Form, Intar sia, structure, Spickel and Kulen is provided.

It is useful that when developing a tax programs for such a knitting machine the input data the Jacquard group an input data subgroup for the knitted fabric front and an input data Include the knit back sub-group. This structuring of the input data is for the user particularly clear.

It makes sense that from the input data of the jacquard Group in one processing step knitting instructions for the needles of at least one needle bed are generated, including thread guide selection instructions for any thread guide not yet specified, with more preference from the input data of the Jacquard group in one Processing stage reassignment instructions for at least one Needle bed can be generated. In an inventive Display of the transfer instructions, especially in overlay The user becomes aware of the connection with the input data of this group. Is the user with him? Not satisfied with the result displayed, he has inventive according to possibilities for correction or changes. At a correction or change remains as with the input data ten groups for a Cotton machine related between input data and the resulting instructions consist.

It is not necessary that when generating the  Thread guide selection instructions are clear, which specific ones Thread guide of the knitting machine should be used. The specific thread guides can be derived from the input data the intarsia group and only when it is generated of the control program the results data of the Jacquard group be assigned accordingly.

It is preferred that from the input data of the intarsia Group a color field in a first processing stage division is derived that in a second processing the color fields assigned to individual thread guides and that in a third processing stage parking and positioning instructions for the thread guides will. This flow for generating the instructions for the thread guide at the knitting machine in question has the same benefits as above related to the generation of parking and positioning instructions for the thread guides of a cotton machine. It will here it is also clear that the workflow for the intarsia Group with a cotton machine and a flat knit or, with restrictions, circular knitting machine in essence Chen is the same.

It is preferred that from the input data of the structure Group in a first processing stage that too stric kenden meshes of substructures, such as. B. braid or Sweetie, set and knitting instructions for at least a needle bed will be generated and that in a second Processing stage reassignment instructions for at least one Needle bed can be generated. As with processing the input data of the aforementioned input data groups for Cotton or knitting machines remain the generation of Knitting and shoulder instructions for the user clearly bar and understandable. The correction according to the invention avoid possibilities at the end of a processing stage unnecessary calculations, since the possibility of correction to the  The time or point of the workflow is given, on which the relevant result data are available and before further result data based on this are generated. The user can transition from one processing level easily understand the next one.

A means of control over the shoulder instruction Solutions for the at least one needle bed is special sensible. The user can do more by making corrections wise optimize the transfer instructions so that less Passes through the knitting lock are necessary. From this results a time advantage when knitting the knitted fabric, here of the knitted fabric.

The input data of the form group are expedient for the generation of the instructions for the thread guide Basis of the input data of the intarsia group and the knitting or transfer instructions for the at least one needle bed based on the input data of the structure group inspects. This makes work easier for the user tert.

It is preferred that when generating the tax pro gramms the knitting instructions of the substructures of the structure priority over the knitting instructions of the jacquard Have group. This provides that the input data the basic structure of the knitted fabric determine while through the input data of the structure Group deviations from the basic structure, e.g. B. braid or nutlets. This hierarchy is special It makes sense because the input data of the jacquard group in Relation to the input data of the intarsia group in particular also concern larger patterns, while the input data of the structure group primarily smaller part structures or arrangements of smaller substructures such as B. concern braid or nut. Regardless of that  a clear assignment due to the given hierarchy between input data and resulting knitting instructions given, whereby the user through detailed work within the respective group to the desired one knitted fabrics can come. A later pattern variation using, for example, the developed structure is quick and easy to do.

It is advisable that from the input data the Group in one stage stitch size instructions generated for the needles of at least one needle bed will. The generation of the stitch size instructions hereby follows regardless of the other knitting instructions based on the other input data groups. For the As a result, the user remains as stated repeatedly get the overview. Through the invention The user can store when specifying the amount simply on the from the input data of the structure group the resulting substructures and take into account if necessary, a corresponding mesh size at the location of the Provide substructure.

It is preferred that the input data of the Spickel group the position of a spiked insert in the stitch product and only one that concerns the insertion of the ax Plurality of input data groups from the set: jacquard, Form, intarsia, structure and design include. A spick The insertion of el in a mesh certificate is therefore defined by their position in the knitted fabric as well by a plurality of input data groups from the same set of input data groups for which the Insertion of knitted fabrics surrounding the knitted fabric (in general with the exception of a Spickel group - a Spick el insertion within a Spickel insertion would also be not very sensible, but in principle nevertheless conceivable). See you use the same input data for the  Groups as for the one surrounding the spiked insert Knitted fabrics, this is how the user defines the Spickel insertion particularly easy.

It is particularly preferred that the input data groups the spikel insertion regardless of the input data Groups of the surrounding knitted fabric in the same way and Way how these are processable. This results in for the user in the definition and processing of the Spickel insertion practically no difference compared to that Definition and editing of the Spickel insertion in the finished knitted fabric surrounding knitted fabric. It is even conceivable that certain for a normal knitted fabric developed patterns and structures for a Spickel-Ein be taken over. Conversely, patterns and Structures of a Spickel insertion in a normal Ge knit (without spikel insertion) are adopted.

Processing in the same way as the input data ten groups of the Spickel insertion like the input data Groups of the surrounding knitted fabric means in particular that the input data of the individual groups and the result data of the processing stages based on the input data th of the respective group according to the invention also in Overlay can be displayed. This representation is independent of the representation of the input data or the result data for the surrounding knitted fabric.

With these display options for the input data Groups of the Spickel insertion or the resulting Result data, it is completely sufficient that in the gra phical representation of the input data group "Spickel" Position of the insert by marking the Spikel-insertion bordering meshes of the surrounding Knitted fabric omitting the spiked insert darge is posed. On the contrary, from this graphic representation  Position of the Spickel insertion result in particular other advantages, because the surrounding knitted fabric is complete and is displayed regardless of the spiked insert. It collections can be easily used as pattern without inserting a spit. The pattern of the Spickel insertion can be done independently and the Spickel Insertion can optionally be done using the Spickel input data Group inserted in otherwise finished knitted fabrics will.

It should be pointed out again that with the device or sample system according to the invention Let statements develop from which either Control programs can be generated based on a knitting machine machine, especially on a flat knitting machine or on a coating machine, especially on a Cotton-Ma are executable. A patterning according to the invention system can therefore be intended for both Knitting machines or control programs for waving machines produce. Depending on the machine for which a tax pro to be developed are the corresponding ones Program development units and the corresponding Activate control program generation unit.

A transfer of the pattern result between one Knitting machine and a knitting machine is largely possible Lich. The input data groups intarsia, form and petinet the Cotton machine correspond to the input data groups Intarsia, shape and structure of the knitting machine. The ent speaking input data or the derived data Instruction sequences always lead to the same principle Knitted fabric regardless of whether it is knitted or has been made with a knitting machine. Of the So far there has been no laying process on a Cotton machine Correspondence with a knitting machine. At through Cotton- Machine-made knitted products are made by  Mesh structures formed at the moment are seldom used.

Also the transfer of a sample result from a Knitting machine from a manufacturer on a knitting machine another manufacturer or a knitting machine Manufacturer on a knitting machine from another manufacturer is with the sample system according to the invention without Pro bleme possible. As long as the machines in question are in the number of meshes available contributing or mesh-influencing machines do not distinguish elements significantly, only needs one corresponding control program generation unit provided are used for the machine-specific generation of the tax pro gramms from the input data groups already available or Result data of the processing stages.

The sample system can also be provided only generate a machine-independent control program. An implementation of the machine-independent control program for respective special machines can then by a separate conversion unit, which is part of the respective Machine or is a separate device. This results in great flexibility advantages in the Manufacture of knitted fabrics.

The invention is based on two Ausfüh Example with reference to the attached figures described. One embodiment is for generation a control program for a cotton machine, while the other embodiment for generation a control program for a flat knitting machine is seen. With regard to the essentials of the invention However, there are no differences between the characteristics a flat knitting machine and a circular knitting machine, so that the following description of the second embodiment  shape could also refer to a circular knitting machine.

In the accompanying drawings:

FIG. 7 is a graphical representation of various input data groups for the device according to FIG. 6 as well as result data of various processing stages resulting from the input data of the respective group.

The general structure of the device or sample system designated by 10 is shown in FIG. 1. The input of the individual input data groups or any necessary changes can be entered using a keyboard 12 or a mouse 14 . In addition, a graphics tablet can also be provided, possibly instead of a mouse. The input and change inputs are received by an input unit 16 . The input unit 16 is provided with a storage unit 18 , which is symbolized in the figure by a diskette as a data carrier. Input data can be stored and read in again by means of the storage unit 18 . A graphics unit 20 , which has a screen 21 for the display, is used to display the input data.

Furthermore, 16 parameters can be entered via the input unit, which relate to the processing options and processing sequences, possibly including the knitting options (e.g. number of thread guides available) of an underlying general but special knitting machine.

To process the input data, the patterning system 10 has five program development units which are assigned to input data groups of the input data. The program development units and correspondingly the input data groups are designated by the names "intarsia", "form", "petinet", "plating" and "laying"; these program development units are identified in the figure by the reference numerals 22 , 24 , 26 , 28 and 30 .

The input unit 16 supplies the program development units with their respectively assigned input data. The respective input data are processed within the program development units, as symbolized in FIG. 2. The top row of individual graphics 40 a, 42 a, 44 a, 46 a and 48 a symbolize the input data of the intarsia, shape, petinet, plating or laying group. The respective individual graphic also corresponds to the graphic representation of the relevant input data on the screen 21 in the event that these input data are considered individually. However, the display on the screen 21 is in color; in Fig. 2 shades are represented by hatching. In this context it should be mentioned that white is also considered to be a separate color like any other color, although this is not shown hatched in FIG. 2.

As a first step, the intarsia program development unit 22 derives a color field division from the input data of the intarsia group. For this purpose, the input data of the form group are fed to the intarsia program development unit 22 by the form development unit 24 and are taken into account accordingly in the color field division. The single graphic 40 b of FIG. 2 symbolizes the color field division, as can also be displayed on the screen 21 . When it comes to the color field division, the intarsia program development unit 22 proceeds in rows and assigns a common color field to loops of the same color that are connected in any direction.

When entering the corresponding individual graphics 40 a, the user has provided that an oval, z. B. the color red (hatched diagonally from top left to bottom right), is arranged on a white background, with the knitted product the red oval by intarsia technique it should be witnessed. The colors mentioned here do not need to be the real colors that appear in the finished knitted product. The colors can be determined during production by appropriate choice of thread when producing the knitted fabric.

The individual graphic 40 b shows the color field division determined by the intarsia program development unit 22 , taking into account the shape input data. It is noticeable that the program development unit has assigned its own color field to the left and right of the oval, although the user has also provided the white basic color here. From a technical point of view, it does not matter whether the same color or a different color is to be knitted to the left and right of the oval, since a separate thread guide is required to the left and right of the oval. In total, three thread guides are required in the rows going through the oval. The white areas above and below the rows with the oval are also separate color fields, both of which are shown in white for the sake of simplicity. The hatching of the individual graphics 40 b correspond in the graphic representation on the screen again colors, z. B. green for the horizontal hatching, blue for the dotted hatching and yellow for the oblique hatching from bottom left to top right.

The result data of the color field division, that is to say the recognized color fields, as exemplified in individual graphic 40 b, form the basis for the next processing stage of the intarsia program development unit 22 . The intarsia program development unit assigns thread guides to the recognized color fields. Color fields for which the same thread guides are responsible are given the same colors in the representation of the result data in accordance with single graphics 40 c. According to single graphic 40 c, the intarsia program development unit has recognized that the area above the oval, the area below the oval and the area to the left of the oval can be taken over by a thread guide. However, it would also be possible for the areas above, below and to the right of the oval to be assigned to a thread guide.

The result data of the color guide assignment processing stage, as exemplified in individual graphic 40 c, form the basis for the subsequent generation of instruction sequences for the assigned machine elements of the knitting machine, here the thread guide. The instructions to the thread guides are in particular parking and positioning instructions. In single graphic 40 d are such parking and positioning instructions for the thread guide which is assigned to the color box to the right of the oval represented symbolically. The parking and positioning instructions are displayed as a path to be covered relative to the mesh product to be used. In reality, the thread guide only moves in the direction of the rows of stitches, i.e. across the direction of manufacture. The parking and positioning instructions are vectorial instructions which indicate the next increasing position relative to the last position, the stitches (including stitches which are not to be used) or needle position serving as position coordinates. The movement to be carried out by the thread guide to form an imaging loop at the binding joint is symbolized by dots in the individual graphic 40 d.

In single graphic 40 d only the parking and positioning instructions for a thread guide, namely the thread guide assigned to the color field on the right of the oval, are visualized. On the screen 21 , one can optionally display the parking and positioning instructions of one or more thread guides.

On the basis of the representation of the result data of the processing stages corresponding to individual graphics 40 b, 40 c and 40 d - the intarsia program development unit is connected to the graphic unit 20 to represent this result data - the user can change or correct the result data by means of the Keyboard 12 or mouse 14 via the input unit 16 . So it is z. B. conceivable that a different assignment of the thread guide to the color fields is cheaper, since this can possibly save one or more thread guides. It may also be necessary to modify the parking and positioning instructions. The thread guides should be parked especially where they do not collide with other machine elements. Another parking position for the respective thread guide can be determined using the mouse 14 . The shape and position of the oval can also be varied.

For simple work, various information levels corresponding to the result data of the processing stages or the input data (these respectively corresponding to the individual graphics of FIG. 2) can be superimposed on one another. By means of this overlay, which will be explained in more detail below, z. B. Simultaneously represent the color field division on which the thread guide assignment is based and the thread guide assignment derived from the intarsia program development unit 22 or modified by the user to these color fields. The input data of the other input data groups and the resulting result data can also be displayed in superimposition with the data of the intarsia group.

The result data of each processing stage of the intarsia group and correspondingly also of every other group can be stored by means of a memory unit 18 'and read in again by the memory unit 18 via the input unit 16 for further processing or for combination with other data for generating a control program for the cotton Machine. The storage units 18 and 18 'can also be the same storage unit.

The Petinet program development unit 26 generates the parking, positioning and decking instructions for the decking devices of the Cotton machine from the input data of the Petinet group in one processing stage. The input data of the form group are taken into account. The corre sponding steps are again symbolized in Fig. 2. The individual graphic 44 a represents the input data as can be viewed on the screen by means of the graphic unit 20 , and the individual graphic 44 b represents the result data of the processing stage mentioned, namely the parking, positioning and deck instructions for the deck devices. It also shows which meshes are affected by the blanket; here in particular the coverage width or coverage widths of the available deck facilities are included. A comparison of the pattern desired by the user with the technically feasible pattern is thus possible.

In the representation of the input data corresponding to individual graphics 44 a, various substructures such as, for. B. Braid or nut symbolized by colors; Corresponding deck instructions are assigned to these colors within the computer.

Just like the result data of the processing stages of the Intarsia groups, the result data of the Petinet Processing level by the user via the input modify it. Of course, as with all Input data groups, the input data are modified. The fact that the instructions for the respective one machine data assigned to data groups are generated independently of one another, an inter active work easier. When working interactively again helps the possible overlay of different ones Information levels, the input or result data of the correspond to different groups.  

This can also cause incompatibilities between the Recognize patterns or structures of different groups and avoid by appropriate modification. E.g. can one Cable pattern at a binding point between two intars sia patterns may be unfavorable; such a constellation can then by moving the braid, for example, by one or a few stitches can be avoided.

In the Petinet group too, the result data of the processing stage, that is to say the instructions for the decking devices, can be stored for further processing or later use by means of the storage unit 18 '. This storage option exists for the result data of all processing levels of all groups. The reading is carried out by means of the memory unit 18 via the input unit 16 .

The previous explanations for the intarsia and petinet groups also apply accordingly to the cladding and laying groups. In the plating group, the parking and positioning instructions of thread guides are generated in one processing stage by the plating program development unit 28 . The representation of the result data of this processing level in the individual graphics 46 b corresponds in principle largely to the parking and positioning instructions of the thread guide corresponding to the individual graphics 40 d. However, the thread guide responsible for the plating does not need to perform a loop for tying at the binding joint.

In the example shown in FIG. 2, a total of four thread guides are required due to the input data groups. Three thread guides are required to produce the intarsia pattern, while another thread guide is required for plating. If the thread guides are not sufficient, the design of the knitted product must be changed if a clever assignment of the thread guides to the color fields of the intarsia group does not help. In particular, it is advisable to provide certain color samples of the knitted fabric not in intarsia technology but in plating technology, provided that the material (the yarn provided) permits this. Fewer thread guides would then be required. The overlaid display of different information levels enables the user to easily clarify the number of required machine elements and make changes if necessary. The fact that the interactivity given by the overlay and the change options makes his work easier.

The laying program development unit 30 generates positioning instructions for laying devices in one processing stage; especially bars. The input data of the laying group are shown in individual graphics 48 a, in the present example there are two strips running obliquely over the stitch product. Such parallel laying patterns can be generated by a laying device. It would therefore be sufficient if only one oblique, mesh-wise graduated line were drawn in the representation of the result data of the processing stage corresponding to individual graphics 48 b, which symbolizes the positioning instructions for the laying device.

In order to give the user an idea of what a laying pattern follows from his input data, the line representing the positioning instructions is displayed twice, each line being positioned so that it represents a laying pattern. In the event that only one laying device were provided and that the user had provided two laying patterns that did not run completely in the same way, the user would at this point deviate between the laying pattern he wanted and that with the one laying pattern. Establishment of technically possible laying patterns can be determined and, if necessary, modifications can be made to its input data according to individual graphic 48 a and to the resultant data corresponding to individual graphic 48 b. For this purpose, the two lines representing the position instructions can optionally also be displayed in the strip width resulting from the input data, corresponding to a number of needles involved.

It doesn't need to run that result data of the laying processing level just like the result data of the processing levels of the other groups further processing or later reuse can be saved. Also with regard to the input or Result data of the Lege group is a superimposed dar position with each other or with input data or result data from other groups possible.

In Fig. 1, the possibility of displaying result data of the processing stages of the different groups is symbolized by arrows that connect the respective program development unit with the graphics unit 20 .

The program development units 22 , 24 , 26 , 28 and 30 of the patterning system 10 supply their generated instruction sequences for the respectively assigned machine elements to a control program generation unit 60 . The data supplied by the form program development unit 24 are essentially the underlying input data in the form prepared for the control program generation unit 60 . No special machine elements are assigned to the input data of the form group, but these input data are important for controlling the machine elements assigned to the other input data groups.

The control program generating unit generates a machine-dependent control program, or a machine-independent control program, for a special knitting machine, from the data or instructions supplied to it, which still has to be converted by a conversion unit 62 into a machine-specific control program. Depending on the knitting machine used, the finished control program can also comprise a plurality of sub-control programs which are synchronized with one another and are to be processed in parallel by the knitting machine and which can in particular be assigned to one or more machine elements. The finished control program can also be a control program based on DIN 66 025.

In the event that a machine type-dependent control program for a specific knitting machine 64 is generated, the control program generation unit 60 can transmit the generated control program to the relevant knitting machine via a data line 66 . The finished control program can also be stored on a data carrier by means of a memory unit 18 ''; this storage unit 18 '' is symbolized as the storage units 18 and 18 'as a floppy disk (the storage unit 18 ''can be identical to the storage units 18 and 18 '). The control program can then be read from the data carrier by the knitting machine using a unit provided for this purpose.

In the case of the generation of a machine-independent control program, the generated control program can be transmitted to the conversion unit 62 for generating a machine-specific control program by means of the data carrier, here the diskette. The conversion unit 62 can in turn save the control program generated by it so that it can be entered into the knitting machine 64 . This process is made clear in Fig. 1 by a disk 18 '''.

The following is now the execution of the discussed selected form of overlay representation of Informa tion levels are explained in more detail, the information level input data or result data from Ver represent working levels.

Basically it is seen in the overlay display that an information level is shown as an active level or processing level in color. The user can determine which information level is selected as the active level by input via the input unit 16. At the same time, he can determine via the input unit 16 which further information levels he would like to have displayed in addition to the active information level.

The active information level is in addition to its representation in Color distinguished by the fact that data input, that is on input data or modifications of result data the processing stage concerned usually only on the data on which the active level is based are effective. In addition, it is optionally possible for data to be entered at the same time towards the several information levels basic data are effective.

In addition to the active layer in the overlay Information levels to be displayed are shown in shades of gray or in shades of gray of the colors of the active information level shown. For this purpose, the graphics unit internally next to a color image that represents the active layer Gray tone image generated that the different chosen represents inactive levels of information. This is any color that is only in the case of a representation as active Information level or when looking at the the respective information level is displayed Associated with gray tone. In the embodiment shown the colors regardless of the processing level or the  underlying input data group each the same Assigned shades of gray.

Any inactive information level can correspond to one of the gray tone image. The depending on the user's choice not to be displayed in overlay active levels of information now become one another superimposes that the gray values of the respective gray tones for each raster point of the representation can be added and each Halftone dot a shade of gray with the resulting sum gray value is assigned.

The overlay of the color image of the active information level and all selected inactive information layer representing the gray tone image is now selected depending on the resolution. For an overview presentation is a resolution with one pixel of the screen or Graphic unit provided per raster point of the representation, where a grid point of a stitch or one does not exist ent of the stitch of the knitted product to be produced speaks.

For this smallest resolution level with one pixel speaking a grid point can be in the active informa one or more colors as transparency colors can be set optionally, which in the overlay in If the smallest resolution level is not displayed. Also in the other, inactive information levels colors can be specified as transparency colors that at least if the relevant information level as active level is specified, in the smallest resolution level is not shown in the overlay. Optional the transparency colors are also used when mapping to the Overlay gray tone image not taken into account.

The superimposition of the color image with the gray tone image takes place in the smallest resolution level in such a way that the color image overwrites the gray tone image to a certain extent, whereby only pixels of the color image are taken into account, to which no transparency color is assigned. For each pixel of the resultant overlay image, it applies that it reproduces the color of the assigned pixel of the color image, provided that this color is not a transparent color. Otherwise, if a transparency color is assigned to the assigned pixel of the color image, the pixel of the overlay image reproduces the gray tone of the assigned pixel of the underlying gray tone image. If the mold is ready (corresponding single graphic 42 a) as non-active level override to ensure the shape definerenden grays out of acting to produce the corresponding pixels to the shape limit in pattern development.

In Fig. 3 the result of such superimposition in the smallest resolution level is shown. The information levels corresponding to the individual graphics 40 a, 42 a, 44 a and 46 a are superimposed. The information level 40 a representing the input data of the intarsia group is selected as the active level; it is accordingly shown in color Darge, which is shown in Fig. 3 by solid hatching and outline. The only color that is not transparent color is the color of the oval, as already mentioned z. B. the color red. The gray tones of the gray tone overlay image are shown in dashed lines in the hatching and in the outline. Due to the described representation in the smallest resolution level, the lower left corner of the yellow triangle represented by a gray tone of the information level 46 a and partial structures of the braid structure of the information level 44 a cannot be seen, since the oval of the information level 40 a is to a certain extent the corner or the partial structures covered.

In addition to a good overview of what is to be generated  Are the lowest resolution level Larger resolution levels are also provided, in which several Pixels correspond to a raster point of the representation, where again a grid point of a stitch or a missing one Stitch of the knitted product corresponds.

With such a higher resolution level, it is the case seen that part of the pixels for each raster point Color of the assigned raster point of the color image ben, while the remaining pixels of this grid point the Gray tone of the gray tone balance on which the overlay is based of the play. This gives you a transpa limit overlay of both the inactive and the active Information level.

The superposition with a larger resolution level having a plurality of pixels 72 per grid point 70 is shown in Fig. 4 and Fig. 5. At this resolution level there is no loss of information regarding the display. The lower left corner of the triangle, not shown at a resolution level, per raster point, and the substructures of the braid structure within the oval, not shown, can be seen at a higher resolution level, as shown in FIG. 4.

The described type of overlay with a higher resolution level leads to the fact that the affected halftone dots retain their color determined by the color image, but the gray value or brightness value changes compared to a halftone dot of the same color not affected by the overlay. Depending on the gray value of the pixels reproducing the gray tone image, a lighter or darker impression of the color of the affected raster point results in the representation on the screen 21 .

The implementation of the overlay between the color image and the gray tone image is explained in more detail below with reference to FIG. 5. Fig. 5 shows a raster point 70 with a resolution of a grid point corresponding to 4 × 4 pixels, or 4 pixels in the horizontal and 4 pixels in the vertical direction. The pixel corresponds to a total of 16 pixels. The halftone dot shown may be a grid point in the area of superposition of the red oval of the information plane 40 a and the gray tone shown as yellow triangle the information plane 46 a, as also indicated by hatching in FIG. 5. The colored pixels, which represent the red color of the oval, and the remaining pixels, which represent the gray tone of the triangle, are now arranged like a checkerboard. With an even number of pixels per raster point, the number of colored pixels and the number of gray pixels are the same.

Due to the chosen type of overlay for a larger one Resolution level as one pixel per raster point is guaranteed does that regardless of the resolution always the same Color image and brightness impression results. Will hang additional non-active information levels superimposed, the gray tone of the gray tone image changes, which is overlaid with the color image, corresponding to the additional tone levels associated with gray tones other. Because of the simple rules of over Storage is intuitive work for the user possible. In particular, the user can control the gray tones of the Grayscale image in your mind slightly the colors of the assign lying information levels.

An embodiment of a device for developing a control program for a flat knitting machine will now be described with reference to FIGS . 6 and 7. The device or patterning system for the knitting machine differs only slightly from the patterning system of FIG. 1 for a cotton machine. Components of the patterning system, which correspond in their function to those of the embodiment according to FIG. 6, are given the same reference numerals, but are each provided with the number 100 . Likewise, the information levels shown in individual graphics in FIG. 7 are correspondingly provided with reference numerals if one of the information levels shown in FIG. 2 in individual graphics corresponds in meaning.

With regard to the program development units or the input data groups and the result data of the processing stages derived from these input data groups, there is a correspondence between the intarsia group, the form group and the structure group for generating a control program for the flat knitting machine on the one hand Side with the intarsia, form and petinet group for the creation of a control program for a cotton machine on the other side. The program development units for these input data groups, that is to say the intarsia program development unit 122 , the form program development unit 124 and the structure program development unit 126 are thus assigned to the program development units of the patterning system of FIG. 1 via the reference symbols in the manner mentioned . The same applies to the individual graphics 140 a, 140 b, 140 c and 140 d of the intarsia group, the individual graphic 142 a of the form group and the individual graphic 144 a of the structure group, which are assigned to the individual graphics of FIG. 2 via the reference symbols are.

There are virtually no differences with regard to the intarsia group, so that reference can be made here to the explanations in connection with FIGS. 1 and 2. However, the results of the processing stages of the intarsia group, as symbolized in FIG. 7, are also important for the knitting of a jacquard pattern, as will be explained in more detail below.

The input data of the form group are important for the generation of instruction sequences for the machine elements of the knitting machine assigned to the intarsia and structure group. Accordingly, the form program development unit 124 supplies corresponding data to the intarsia program development unit and the structure program development unit .

There are differences between the structure group the sample system for a cotton machine and the Sample system discussed here for a flat knitting machine seem. With a flat knitting machine in the case of two or more needle beds to carry out the necessary Transfer operations not to control deck facilities, but usually just the needle beds. Accordingly do not become of the structural program development unit Parking and positioning instructions and of course no deck instructions, but knitting or shoulder instructions for the needles of at least one needle bed are generated. In the event of a flat knitting machine with only one needle bed all Thing is also one provided here for transferring To control deck equipment.

At the end of the first processing stage of the structure input data, the stitches to be knitted of partial structures, such as. B. braid or nut, set and knitting instructions generated for one or more needle beds. The input data are shown in single graphic 144 a, namely nut nuts in the area of the reduction in the upper part of the knitted fabric and two braids in the middle of the knitted fabric. The single graphic 144 c shows the stitches to be knitted of the substructures. Is the base fabric z. B. knitted on the left, so all of the knitting of the basic fabric stitches, ie the right knitted stitches are displayed. If the user can display the results of the first processing stage in accordance with a single graphic 144 c on the screen, he can in turn check the result of the processing stage in particular in an overlay display and, if necessary, the input data of the structure group or the resulting result data on the basis modify this input data. In the next processing stage, the transfer instructions are generated for one or more needle beds. The generated transfer instructions can also be checked by the user or modified if necessary. For this purpose, a window 144 e can be displayed in an information level corresponding to individual graphics 144 d, which displays the transfer sequences for a respectively selected row. Especially with the neck drains, there are many optimization options with a view to minimizing the number of passes of the knitting lock.

As further program development units, the patterning system 110 has a jacquard program development unit 132 , a Kulier program development unit 134 and a Spickel program development unit 136 . All program development units can save the result data of their processing stages by means of the storage unit 118 'so that they can be read in again later by means of the storage unit 118 via the input unit 116 for further processing or for combination with other data for another control program development. The storage units 118 , 118 'and 118 ''can in turn be identical.

In addition to the input data of the different groups, the graphics unit 120 can display the result data of the processing stages for the individual groups on the screen 121 . For this purpose, the program development units supply the result data to the graphics unit 120 .

The input data of the jacquard group are divided into an input data sub-group for the front of the knit and an input data sub-group for the back of the knit. Both input data sub-groups can be entered separately via the input unit 116 and are shown separately via the graphics unit 120 on the screen 121 , as shown in the individual graphs 150 a and 150 b of FIG. 7. The single graphic 150 a corresponds to the input data subgroup for the front, while the single graphic 150 corresponds to the input data subgroup for the rear. The information levels corresponding to the individual graphics 150 a and 150 b can in turn be superimposed on one another or respectively respectively or together superimposed on other information levels. The type of overlay depending on the resolution level does not need to be discussed further here; the patterning system 110 does not differ in this respect from the patterning system 10 .

The input data of the jacquard group, symbolized by the individual graphic 150 in FIG. 7 and consisting of the two subgroups, form the basis for the generation of knitting instructions for the needles of one or more needle beds, with thread guide selection instructions also not yet specific for this phase of the pattern development graceful thread guides are generated. The thread guides available are determined by the input data of the intarsia group. An assignment between the thread guides of the Jacquard group, which have not yet been specified, and the thread guides provided by the intarsia group takes place during the generation of the control program by the control program generation unit 160 .

In a subsequent processing stage, the jacquard program development unit generates transfer instructions for one or more needle beds or for a corresponding covering device from the input data of the jacquard group. The transfer instructions resulting from the input data are symbolized in the single graphic 150 c; the corresponding information level can in turn be displayed by means of the graphics unit 120 and the user can correct the underlying input data or the transfer instructions if necessary.

In the present example, a large A in jacquard technique is to be inserted into an intarsia-knitted oval in the finished knitted fabric, as shown in the individual graphic 150 a. In the area of the oval, only two thread guides are required, whereas if the A should also be knitted using intarsia technique, more thread guides (namely five) would be required. Depending on the number of thread guides required, the user can decide whether he should better have a color pattern knitted using jacquard technology instead of intarsia technology. A transfer of color samples from the input data of the intarsia group into the input data of the jacquard group is easily possible, in particular using the overlay representation shown in detail. However, the patterning installation can also offer the possibility of transferring graphic objects from one information level to another information level of the representation via the graphics unit 120 , which are then converted into input data by the corresponding program development unit.

The Kulier program development unit 134 is responsible for generating stitch size instructions for the needles of one or more needle beds from the input data of the assigned input data group symbolically represented in individual graphics 146 a. The mesh size is displayed in the graphical representation corresponding to individual graphic 146 in a color at a choice as active information plane or in shades of gray with a choice as non-active level of information in the overlay. Each mesh size corresponds to a given color or the corresponding shade of gray. By overlaying the structure input data or the result data of the processing stages of the structure group, meshes affected by the structuring can be provided with a larger mesh size, depending on the requirements of the substructures.

A spiked insert in the knitted fabric to be knitted is displayed, as shown in the single graphic 152 a. In the representation of the input data of the Spickel group, only the position of the Spickel insertion in the knitted fabric surrounding the Spickel insertion in the finished knitted fabric is immediately indicated. For this purpose, the edge stitches of the surrounding knitted fabric are marked on one side of the insert; in the present case, these markings form an oblique line as shown in single graphic 152 a.

The insert itself is defined by separate input data from the groups jacquard, intarsia, shape, structure and splicing in the same way as the knitted fabric surrounding the insert in the finished knitted fabric. For each of these spiked input data groups, the input data, such as the input data groups of the surrounding knitted fabric, are processed by the patterning system 110 in order to generate instructions to the respectively assigned stitch-producing or stitch-influencing machine elements. These instructions are completely independent of the instructions that are generated based on the input data groups of the surrounding knitted fabric without the Spickel group. The input data and the resulting result data of the individual processing stages are in principle interchangeable between the insertion of the pimple and the surrounding knitted fabric. In a later processing step, in particular in the generation of the control program, there is a comparison between the development result with respect to the insertion of the picks and with respect to the knitted fabric surrounding them, e.g. B. also with regard to the number of available machine elements such. B. thread guide; in the event of intolerance, e.g. B. when exceeding the thread guide number, there is a corresponding warning.

The input data groups of the Spickel insertion are symbolized in FIG. 7 by the individual graphics 152 b, 152 c and 152 d and represent the input data of the Jacquard, the intarsia, the shape, the structure and the Kulier group for the spikel insertion. Color patterns or the like are not shown in these individual graphics for the sake of simplicity. In the processing stages mentioned above, corresponding result data or instructions to machine elements are generated from the input data groups of the Spickel insertion, which can be displayed on the screen 121 for optional modification.

The described manner of the definition of Spickelinserts (all the input data defining the Spickel-insertion are represented in Fig. 7 together by the single graphic 152 ) allows an easy change in the position of the Spickel-insertion, in the present case z. B. by shifting the line formed by the marked mesh in the single graphic 152 a. In this way, it can be achieved that color samples which are to appear coherently in the finished knitted product are divided by the spiked insert.

In summary, the invention relates to a device for Development of a control program for a knitting or Knitting machine for the manufacture of a knitted fabric, at  based on different input data groups the generation of instruction sequences for the input group each assigned to contributing to the stitch production or stitch-influencing machine elements of the knitting or knitting machine takes place independently of one another. Here is a modification of the instruction sequences by the user of possible. Only after development of the instruction has been completed sequences are generated for the respective groups Instruction sequences merged to generate one machine-dependent or machine-independent tax pro gramms for the knitting or knitting machine, if necessary with delivery of warnings in case of intolerance.

The facility or sample system is modular and can easily be attached to different knitting or knitting measures seem to be adjusted. The modular structure is both regarding the processing of the input data of various Input data as well as regarding the processing of the Given input data of an input data group.

Within an input data group, the Ver Working or generating instructions on machines elements an increasing concretization towards general control commands with corresponding visualization the results of the processing stages and corresponding appropriate correction options by the user.

Which result from the individual groups of input data Resulting data or instructions only become so late merged as possible to generate the tax programs.

This results in a largely universal structure of the pattern system regardless of whether the control program for a knitting or knitting machine is to be generated.  

Due to the diverse intervention options of the user especially based on a graphic overlay representation of different levels of information, the input Represent data or result data from processing stages animals, there can be technology-related incompatibilities (Knitting or knitting tolerances, e.g. collision between a cable or jacquard pattern on a tie position) and machine-related incompatibilities (e.g. Avoid collision of machine elements).

The invention was above based on two execution examples (cotton machine or knitting machine) in one described, although in an analogous manner without also on warp knitting machines (including Raschel machines) is applicable. The warp knitting machine is largely in independently working meshes end machine elements (laying bars; catch-forming equipment tion) divided. The laying bar is used in particular each assigned a corresponding input data group net for the development of an assigned instruction sequence. The Development results can therefore be passed on in bars be working. For example, with a rubber thread laying bar the elastic behavior of the chains knitted, so the developed instruction for this bar, you can also choose a later one Sampling can be considered immediately.
