Method for producing a pattern tape or the like for a knitting machine

The invention relates to a method for producing pattern tapes, pattern strips or pattern disks (hereinafter referred to as pattern tapes or the like) for pattern control of knitting machines.

A sample tape is used to supply input signals a pattern selector. In the form of a tape, the pattern tape usually consists of a polyester tape with perforations. The holes are punched according to a specific code according to the desired pattern. The pattern selection device the desired pattern is thereby fed in and at the same time the pattern counting device is controlled by the Kusterband.

In the conventional manufacturing process of a Kusterband, the first step is that a cough picture is made of the draft of a Künsi3ers, from which each bag can be seen diagrammatically according to its type (color or the like) and its position in the Iuster area is. As is well known, such pattern images are made by hand on squared paper. This activity requires great skill and it takes several days to record a sexton for, for example, 144 crochet sticks χ 216 rows of crochets. ψ The time required increases proportionally with the size of the area for the same level of difficulty. Zo aauert making a Kuster drawing for 432 ilsschenstäbchen and 432 courses · for example, about 1o days and the production of a pattern drawing for 1726 I.aschenstäbchen una 1,728 courses about a year, it is evident that a considerable amount of time and money can be saved, when the preparation of the chandelier drawings by hand can be avoided.

The second stage in the manufacture of a pattern ribbon or the like consists in punching the holes according to the information contained in the pattern drawing. This transfer, too, is a difficult and lengthy task when you bear in mind that around 30 GOO holes are required for an "oaster area of 144 wales and 216 rows of stitching. This is why it has already been suggested that the information contained in the cutter drawing v digitally converted in such a manner. ^r irc that they received by computer eir.em

can be, in turn, a tape to control a Produces punching device in which the Kusterband is finally produced. In terms of the manual Establishing a liuser drawing encountered difficulties however, it is desirable that the digital conversion of the kuster be done in some other way.

According to the present invention, it is proposed to use a luster band or the like for a knitting machine thereby to manufacture, the sexton ate straight from a sketch, one Drawing or an Iiusterprobe is digitally implemented, and that the I-iuster in the form of digital information is used to reproduce the information in a to produce the Programmed Kusterbandes or the like in a suitable manner Computer is fed.

The computer can according to a further feature of the invention also be programmed to the effect that a printed sample image for monitoring the digital conversion and a strip of paper or a magnetic tape for controlling a striking tool or other manufacturing facility of the i-iusterbanäes or the like is generated.

The sample image generated by de: a computer can be based on a Another feature of the invention can serve as a basis for entering improvement information into the computer.

for example one known under the name D-mac Establishment. When a follower is moved across a table, its position can be determined by the digitizer in χ and y coordinates are determined at intervals of 0.1 mm in each direction. When a switch is operated the digitizer punches these coordinates in a paper tape. The connection between the successor institution and the The table only consists of an electrical cable. Therefore, the follower can be moved freely.

The D-mac digital converter can be used in two different ways:

a) position

b) line.

In the first-mentioned type, when the switch is operated, only the coordinate of the downstream device is displayed in it Time punched into the tape. No other coordinates are holed until the switch is pressed again. When the digitizer is operated in line, the coordinates of the position of the follow-up device are determined in advance Time intervals as long as the switch is actuated, punched into the paper tape. The time interval can can be set by the operator in order to be able to follow the respective process. When actuated in "line" you can the operator also records the color boundaries of the larger parts of the pattern. So that the computer can a corresponding input information can be given, without it being necessary, each individual mesh point to record. Since the coordinates are in constant time intervals

vallen, the distance between the individual positions of the follow-up device depends on the speed with which the successor device is moved. If the successor organization quickly has a smooth line is guided, the coordinates assume positions that are far apart the successor organization is run more slowly and the individual positions are closer to one another. In this way, the various designs within a pattern defined by the spacing of the coordinates along the lines will.

In addition to the digital implementation of the outlines of the various designs Within a pattern area it is also necessary that the color of the individual stitches is defined and recorded on the paper tape, and that the means for digital conversion is one of the follow-up means having actuated control panel. This enables this additional information to be punched into the tape. the The switchboard is provided with various control devices as well as a number of switches, each in a number different switch positions brought v / ground. When the electrical panel is set in a certain way and then a control element is actuated, special information is output from the machine, which is entered into the Tape is holed and which is used in conjunction with the holed instructions for the coordinates.

In this way, the color of an outline and that of the stitches on both sides can be entered into the tape, before the outline is traced. In general, the three possible colors are different. Are the colors on both sides the same as the outline, but different from the color of the outline, the result is a single-colored box line on a background of a different color. Such a condition would result from a certain switch position on the control panel so that when the tracking device is passed over this part of the pattern, the holes punched in the tape not only show the position of the coordinates but also the color in this particular zone.

If the outline is the same color on v / as that on one Side of the outline lying I-la, this means caß a single-colored zone to a zone in a different color part; adjoins. If such a zone is traveled by a sexton, the switches on the control panel are set so that this particular color position in the band simultaneously with punched in the holes corresponding to the coordinates.

In addition to lines and areas, sextons also contain individual single meshes. The positions of these individual pockets are registered on the tape by moving the downstream device to the corresponding position and then actuating the switch. The earbe of the i-iasche (or the Kaschenart) is also taken up by the Bana by adjusting the control panel accordingly. Zs is sorbitol possible, besides

the mesh coordinates to record information about the mesh type at the same time.

Ss very often happens that an area is not linked to a single Color is filled in but with a regular mixture of colors. Under the designation "regular color mixing" is supposed to a mesh pattern can be understood which consists of a repeating sequence of identical small mesh patterns. The number these blends in a pattern can be very large. According to the invention, each individual mixture is given an identification number or assigned a code. A certain switch position on the switchboard of the digital converter corresponds to this code. Details of the repetition of each color mix can be found on punched cards in a suitable format for input into the computer Form to be held. One mesh of the color mixture is used as a data mesh. When the pattern is traced, the position of the data mesh of an area is recorded by the digitizer as a stamped code on the tape. When this coding is analyzed by the computer, it is determined according to the recording card in the computer converted back into the corresponding color mixture. Information is also recorded by the computer that the Color mixing is within the boundaries of a range. Contains a pattern is different demarcated areas each with the same color mixture and is also for this mixture only If a date is specific for this color mixture, the computer registers all these areas in such a way that the color mixture

for the different areas is contained in the correct memory for the different areas.

A D-mac or a similar digital converter can of course also be used to digitally convert the information from a sample image used if one already exists for the pattern in question. Such a sample image can be used according to the conventional method or consist of a computer print. According to a further feature of the invention The invention also includes a method for producing a pattern tape or the like, in which the pattern information is converted from a sketch, a drawing or a sample image into a digital sample information, whereby a D-mac or a similar digitizer is used.

The invention is explained in more detail below with reference to the drawing, in which the individual process steps are shown in the form of a block diagram.

The block 1 shown in the drawing represents the original pattern that lies on the table of a D-mac digital converter 2. Pattern 1 is followed by the operator. A perforated strip 3 is thus produced. A program represented by box 4a is input to a computer 4. At the same time, the information contained on the tape 3 is entered into the computer. The computer 4 has two outputs on, namely a device for printing out a sample image 5 and a magnetic tape 6, which the sample image in In-

Formation form contains.

The block 7 represents a device for visual monitoring of the printed pattern image 5. This checks whether the pattern to be produced actually meets the ideas of the Corresponds to the pattern designer and is otherwise acceptable. If changes are required, the required Corrections entered in sample image 5. This is shown by block C 1. This information is then in turn is entered into digitizer 2 and the cycle begins again. When no more changes are required, the Information content of the magnetic tape 6 in its final version in turn to the computer 4 or, if necessary, a entered another computer. This is programmed with another or further program represented by block S, in such a way that the output information is put on a paper tape or magnetic tape. The ones in this volume The information contained therein is used by an automatically operating percussion tool to punch holes in the much heavier polyester tape entered. The final sample tape is made from the polyester tape. The paper tape or magnetic tape is marked with 9 and the striking tool with 10 «The perforated polyester tape, which can be used as a sample tape, is denoted by 11.
