The present invention relates to a pattern device for circular knitting machines, in particular Round edging machines in which a common endless selection belt with a large number of selection wheels works together for the purpose of a pattern-based selection of those located in the selection wheels Selector plates, which after their selection to act on the knitting tools to be selected Machine can be moved automatically into a working position and then either repeated as often as required of the pattern can be locked in this position or via an automatically switchable trigger part as well can be returned to their original position via control bodies for renewed selection the selection tape. Such pattern devices are used to select and adjust knitting tools for the purpose of optionally generating any mesh or color patterns or other types Mesh bindings, as they are z. B. in goods with dividing row, fixed beginning and find the subsequent transition to 2: 2 margin.

Pattern or selection devices with an endless selection belt are already known.

In one embodiment, the selection tape contains only a single pattern of any height, and the appropriate ones Sample wheels are designed in such a way that the selector plates housed in them are Transfer your selection to the knitting tools again and again in the same starting position to return. This device is described in German patent specification 837 746. That In this case, the selection band only plays the role of a sample band.

Also serving only as a pure sample band, a selection band can be used in a further variant according to German patent specification 854 558 record a plurality of patterns, which then one after the other, each covering a section, although the height of the motif is limited because of the Generation of the same only one machine revolution is available.

So it is not possible with these known arrangements, several patterns of any height in the to accommodate the same sample tape and thus automatically from one to one in the same knitted article to pass another pattern of this kind.

The above considerations relate primarily to pure jacquard circular knitting machines, which manufacture colored sample by the meter as the main product. Circular knitting machines, on the other hand, on which they are fitted like this Pieces of goods with a fixed edge and unlimited dye or machine patterns are executed Pattern device for circular knitting machines

need, in addition to a corresponding sample device, a special switching system for all those organs involved in the knitting process which are responsible for executing the automatic transitions are necessary for the formation of the edge and from the edge to the length of the article. It is one of the classic structural forms of the fixed edge, which is made up, for example, of dividing row, fixed stop, Transition rows and 2: 2 margin, in other words, composed of a large number of consecutive different types of stitches and needle selections. Usually, specials are seen to perform all of these operations automatically Switching and control devices based on mechanical, electrical, hydraulic, pneumatic or otherwise act on lock parts and knitting tools. Such facilities lead, especially with multi-system round-edged knitting machines, to quite complicated and clarity as well as the accessibility of the machine severely impairing constructions. As a result of the inevitable Many of the control and transmission organs required for this purpose, moreover, their functional reliability is often undesirably reduced.

The present invention has the task of eliminating all the drawbacks mentioned and one To create a pattern device for circular knitting machines, in particular circular edging machines which not only the pattern-based selection of knitting tools for the production of several, as desired large mesh or color patterns, but also the setting of those involved in the knitting process movable organs for the purpose of producing different ones

The sequence of movements described above takes place with every revolution of the needle cylinder.

Should now the automatic transition from one pattern or knitting type to another pattern or another type of knitting takes place, the respective second row (II) of cutouts 39 in the selection band 26 used.

For this purpose, the switching takes place before the actual readjustment of the selection boards 20 the run-up slope 32, which opposes the desired starting position II (FIG. 3) of the selector plates brings about the selection belt, by lifting this run-up slope 32 with the help of a switching device not shown. The movement of the run-up slope 32 is completely safe because the outer feet 31 of the selector boards 20 are out of reach of the same and as a result no intermediate position can occur (Figs. 1 and 6).

Then all the selector boards 20 are then back down into the deepest one, as before Position and brought outwards, they find the run-up slope 32 already in the desired height position before, run with the outer foot 31 on the inclined plane 32 α (FIG. 3 a) and thus get the starting position II opposite the selection belt 26, which then in the manner already described the makes a new selection (Fig. 3).

Due to the counter-rotating principle of the selection belt opposite, which is common to all selection wheels the direction of rotation of the needle cylinder, as is known, makes a second type of selector sinker 20 necessary, which is provided with a nose 25 '(Fig. 2) offset in relation to the first type, which cooperates with corresponding cutouts in rows Γ and ΙΓ of the selection band 26 (Fig. 4).

Since in the described and illustrated embodiment only two different starting positions of the selection boards 20 are accepted, the associated selection tape 26 also contains only two Double rows I, II and I 'and II'. However, as already indicated, there are still other starting positions conceivable, in which case the selection band also has a correspondingly larger number of double rows would exhibit.

In the example, the selection belt 26 is also assumed to be a hardened steel film, with mechanical Action on the noses 25,25 'of the selector plates 20. As a result, the cutouts 39 appear individual selection groups as adjacent, circular, square, rectangular or differently shaped punched holes, between which a narrow separator remains. The inventive idea can basically just as well be used on selection tapes made of other material (e.g. non-ferrous metal, Paper, plastic, textiles, etc.) and for other types of recording of the selection groups with accordingly adapted reading systems (e.g. electrical, magnetic, optical and other Ways).

Finally, the drawing only illustrates a selector wheel for the cylinder needles of a circular knitting machine. For practical and technical knitting reasons, as already mentioned, the arrangement is such Selector wheels are also desirable for dial needles. Since the latter selection wheels in principle completely are constructed in the same way as the cylinder gears and are only different from these for the invention To distinguish irrelevant details, a special description and representation of them is necessary been disregarded.
