The pegboard has the other great advantage that you can see at a single glance whether the desired pattern repeat has been inserted correctly and, so that it has been correctly stored. In addition, pattern repeat changes can be carried out quickly. One According to the invention, such a repeat pattern change can be further facilitated and accelerated by the fact that the Heads of the plug in a congruent with the plug = position arrangement of the pegboard perforated, preferably be anchored in a sufficiently long guide using a transparent retaining plate or film. A desired one Pattern repeat can therefore be inserted in front of such a holding plate or holding film and stored until it is used. All plugs are then inserted at the same time by placing the retaining plate or retaining film on the control panel by pushing all the connectors into the associated plug-in points on the board »The other way round can be done by simply lifting off the retaining plate or retaining film Remove all plugs from the pegboard again at the same time from the pegboard, thereby removing the information content is deleted, and the retaining plate can be kept with the plugs in the unchanged pattern repeat arrangement if desired until the relevant Pattern is to be knitted again on the machine. Also the entire pegboard including the Switching levels can be designed to be interchangeable «Their individual structure depends on the number of machines with the machine different to be produced or processed

A plug-in diagram as a mother program carrier according to the invention is constructed, for example, as a plug-in matrix with about 100 rows and 100 columns. All practically occurring pattern repeats with a width of up to about 100 wales and a height of about 100 rows of stitches can be stored on the pegboard on this plug-in matrix and its repeat height is a whole multiple of eight rows of hash, for example 24 rows of hash. In addition, the cough should have four different colors.The pattern device, the pattern program carrier of which is the pegboard, should be designed for a circular knitting machine with 36 knitting systems, whereby the systems only knit one yarn of a certain color, i.e. are not equipped with thread changing devices. Electric coughing devices according to the invention can in principle also be designed and programmed for circular knitting machines with thread changing devices, but in this case a fairly large ¹ circuit complexity is required, which should be avoided if possible. The electrical pattern device considered as an exemplary embodiment should also have 18 electromagnetic actuators per knitting system, with which the pattern selection of the needles or needle pusher takes place and which must be sequentially switched according to the pattern repeat stored in the pegboard. In the introduction it is also noted _r

that when knitting with several colors, one of the machine's knitting systems can also be switched off, what can be readily taken into account by the electrical pattern device, and that the considerations are not limited to yarns of different colors "but that in the execution described below" - For example, instead of four different thread colors, different thread types of the same color and even different stitch shapes in the knitted fabric (catch stitch formation etc.) could occur.

In FIG. 1, a 3-tteoctable table is shown in a schematic catfish shown, which has a male part · for each knitted fabric. ! These Steoketellen show themselves to the outside as Holes 401 in a cover plate 402 of the panel, and pins 409, 404 can be inserted into these plug-in holes 401 and 405 of different lengths can be inserted · The pins are made of electrically conductive Material produced and provided with heads 406, which are expediently in the relevant thread color in which the the stitch corresponding to the stake is to be knitted, are colored, or their head shape is different so that the pin head can be used to check the pin head at any time to see if there is a pattern has also been saved correctly and no steering errors are present.

This problem is solved according to the invention in that the pegboard is divided into several individual panels, or panel sections, whose mesh bar connection number is at most equal to the whole number of needles in the distance between two successive knitting systems are present in the needle cylinder. The number of repeat memories, the circuit | for system assignment per row of lugs, the partial pattern signal admitting, the system sequential circuit and the assignment switchgear are at least partially provided several times, the assignment switchgears so coordinated with one another are that there is a smooth query transition from pegboard section to pegboard section »As from FIG. 5 As can be seen, two pinboard sections 460 and 470 are provided, the first of which is the pinboard section Entries 461 for the first 54 crochet wales per row of a pattern repeat and the second pegboard section 470 Maachene inlets 471 per row of stitches for the wales 55 to 103 of a pattern repeat, with the 54 stitches per row of the ' Second memories 470 are usually only partially connected because the pattern repeat width is arbitrary should be selectable up to the full number 108.

Also the one in Figure 5 on the right System assignment part 365 shown on the side and the cylinder straight rotation assignment part shown on the left-hand side of the figure 366 of the assignment switching mechanism 360 each have two separate control program carriers 367 and 368 as well as 369 and 370. However, the circuit can be simplified to the extent that, despite the double prograi, only the simple number of electronic Gate circuits are required so that one does not double the number of gates with the many inputs and outputs in the assignment switching mechanism 360 needs. According to the invention, this is achieved technically in a manner not shown in detail and in various ways Realizing device achieved, which is preferably via a mechanical Umsehaltanordnung, which are attached to the mechanical part of the assignment switchgear can cause a mutually alternating signaling of the assignment switching mechanism to the two pinboard sections, so that the pinboard sections have a common Circuit for a system assignment - per row of stitches and a common logical linking circuit can be assigned. In Figure 5 is this device symbolized by a box 380 in which on two separate lines 381 and 382, the individual Pegboard sections 460 and 470 are assigned, control impulses follow 383 and 384, the individual im-
