formations corresponding coughing events and with gates, bistable switching elements, memories and Amplifier stages via which the pattern signals syn ~ the excitation state of the electromagnets of the actuators chronized with the needle cylinder rotation movement *

It is already known for electrical pattern devices of the type described above to use film tapes on which pattern signals are encoded are (British PS 1 091 547). This sample program carrier but have the disadvantage that they need an expensive device for their creation and for this reason only are made by the knitting machine manufacturer herself according to the pattern templates of the knitting mills can. The object of the invention was to remedy the serious disadvantage mentioned above and to design a sample program carrier in connection with the reading device assigned to it so that the The prerequisites for this are that the sample program carrier can also be produced in a knitting mill itself according to a desired template «

This object is inventively achieved in _f that there is provided from the needle cylinder driven multitrack tape as a pattern program carrier on which each is assigned a separate track to be knitted partial pattern and on which the information for the actuators groups on the individual and on the periphery of the machine consecutive knitting systems

The sample program tapes shown as exemplary embodiments in the drawing must be designed for the sample device of a multi-system circular knitting machine "which has 36 knitting systems, has 2232 needles in the needle cylinder and where the normal spacing aw knitting systems on the cylinder circumference is 59" 52 needles "The actuators should for example by direct current reversing magnets »to which a signal" Knitting ¹¹ or a signal "Niohtatriöken" must be sent «The cough report width should be 50 crochet sticks or an integer multiple thereof» The stated values are not binding and are only intended to provide a better understanding of the The following explanations serve ο

In Figure 1, a cough program tape 101 is, for example, a perforated tape, with four program tracks 1 to 4 schematically shown "This tape is intended to serve as a fixed pattern memory for a knitting machine" on which two partial patterns are knitted with two different colors Program tracks 1 and 2 are assigned to sub-pattern I and program tracks 3 and 4 are assigned to sub-pattern II. On the two double lanes should

109826/0393

lanes 1 and 3 contain the information "knitting" and lanes 2 and 4 contain the information "non-tri-token ¹¹ "

On the knitting machine, the successive Striok systems should alternately knit a different color »so for example the Strioksystest St ₉ S3» S5 *

57 the partial pattern X with one and the knit *

systems S2, S4, 36, S3 .... the partial pattern IX with the assigned to another color «

Since the belt 101 is to be driven synchronously with the needle cylinder, it would be advantageous if the belt on the program tracks of the tape 101 applied information for the individual Strioksystems in the correct order by as many information storage places from each other are applied remotely »like needle steps at a distance χ between two successive knitting systems are. Since in the selected embodiment of the Abetand χ * 59.52 needle steps, i.e. an odd one Number, this requirement can be met with a commercially available program carrier tape, in particular punched tape, that with standard commercial writing devices should not be described. It will therefore be the closest in terms of the division of the belt Nearest even number chosen, in this case 60, and the double apur reading heads 110 for the tracks 1 and 2 and 111 for tracks 3 and 4, which are only symbolically indicated by arrows in FIG. 1, are used in

The run of the tape in the opposite direction to the fourth tape run eo ver-β divides, dej the ableaebeglim of each subsequent system occurs when needles run past the needle cylinder 59t52 are * This corrective movement is reversed after a full revolution of the cylinder, so that the scanning process for the next cylinder turn * - hung again properly starts from the beginning 36 sum S tricksy st em 1, in which area because of the needle for the spacing of the striocular systems in general is greater than the otherwise even normal distance between the systems «

As can also be seen from FIG. 1, the the dual track read heads 110 and 111 in the tape direction 2 «60 - $ 9.52 - 0.48 division steps of the band offset from one another because the cough information for successive S tricksy et erne SI, 82 etc., alternately are applied to one or the other of the double tracks 1, 2 and 3f 4.

Figure 2 shows a Mueter program tape 102 with six Single tracks 1 to 6, so three double tracks for that Knitting with three colors in the successive partial patterns I to III "Partial pattern I is the two Program tracks 1 and 2, the sub-pattern II the program » tracks 3 and 4 and the program tracks 5 and 6 assigned to partial pattern III The individual program track sections for the consecutive Strickeyeteme 31 ....... S36 are arranged in a staggered manner as in the case of the four-lane tape 101 »with the assigned to the individual knitting systems Track areas each begin with a mutual spacing χ »In the present case, the assigned track areas are arranged in staggered three» and it can be seen from FIG. 2 that the knitting systems

31, S4 »S7t 310 and the part I, the Strioksyeteme

32, S5 »S8 etc. the part pattern II and the knitting systems S3 »S6» S9 etc. are assigned to sub-pattern III «.

When knitting with four colors in four consecutive » the part omatern is shown in FIG. 3 Program carrier tape 103 with eight program tracks »that is, four double tracks are used for partial patterns I to IV

109826/0393 " ¹⁰

In this case, the information from four successive strioc systems is always arranged on the four double tracks in the staggered form already mentioned. Four double-track reading heads 110 * 111 »112 and 113 are provided, which vary from double track to double track by the difference ζ between the selected uniform program division step of the tape (here 60 division steps) and the number of needles between two successive Striok systems (here 59» 52 needles) - ^ are set. This means at the selected game Ausführungsbel- Ψ displacement ζ of 0.48 Programmteilschrittenο In the aohtspurigen Muaterprogrammband 103 thus follows the first, the partial pattern associated with I double track the information for the knitting system S5 at a distance of

4 times JC, in the present case 4 times 60 tape division steps, to the information for «read Strioksystem U. Since the distance between knitting systems 1 and 5 on the circumference of the knitting machine is only 4 times 59» 52 needles in the example chosen, we know the assigned double track - Scanning head 110 »which scans the two program tracks 1 and 2, over the length range of 4 times χ an additional movement of 4 times s graduation steps is issued so that the coughing information for the knitting system

5 is scanned in the correct sequence Dual track reading heads 111, 112 and 113 are issued <> The adjustment movement mentioned must cover the entire program range for the 36 knitting systems of the machine and thus over a whole revolution of the needle cylinder both

In Figure 3 is different from Figures 1 and 2 of Case takes into account that the pattern repeat width in an » number of crochet hooks is not less than the mutual system spacing in number of consecutive needles, it exceeds this system spacing »A sample repeat width of 100 Masohenetäbohen is assumed here. which corresponds to a track length on the sample program tape of y «100 tape divisions. From this it follows' that the track sections y overlap on the individual double tracks and the case occurs that on two of the Double-track reading heads 110 to 113 pattern signals can occur simultaneously «, the mutual distance χ the beginning of the individual system areas on the sample program tape must remain unchanged, since it follows the mutual distance between the systems on the circumference of the knitting machine. program tape 104 according to Figure 4 for knitting with four successive sub-patterns I to IV in one Pattern repeat width of e.g. only y »36 wales on the other hand, there is no overlap of the individual knitting system areas on the belt 104, so that here four double-track reading heads that are not registered are only ever supplied with one sample signal «

For writing and reading sample program tape a simplification can still be achieved. So it would be an advantage for punching a perforated tape if one
