Fig. 9 shows a circuit which allows part of the pattern that is common in a given knitted fabric would appear to replace with another cough, and

Pig. 10 is a block diagram for the case where the knitting pattern is reversed by means of the circuit of FIG will.

In Fig. 1 a block diagram is shown for the case in which a pattern with three colors, red, blue and white on a circular knitting machine, hereinafter Called a bundle knitting machine, with 12 yarn feed devices and a total of 756 knitting needles is worked.

The original 1 shown in Fig. 2 becomes row by row into coughing signals of the binary number system or any other appropriate system and stored on tape or other suitable storage medium. By doing Case in which the conversion by means of. ^ Ines binary number system & ~ tems takes place, picks up the signal in a given row of the Knitting pattern has the value "1" or "O" depending on the Presence or absence of a knitting operation at the corresponding knitting position. In the solder Heihe of the knitting pattern of Fig. 2, for example, the cough signals of the color system are red (indicated by the marking X) 0OO110OO01100O00, those of the blue color system (indicated by the marking 0) 0000011110000000 or that of the color system white (indicated by the absence of a marking) 1110000000011111.

The stored pattern signals are read out by the reader 3. The pattern signals of the red color system are through

009883/1623

the gate circuit or gate 4a out and passed on to the pattern register 5a and temporarily stored there. In the same way, the pattern signals of the blue color system are passed through the gate 4b and temporarily stored in the pattern register 5b. The pattern registers 5a and 5b are composed of such a number of paired ring registers 6 and 6 * or 7 and 7 ¹ , which equals the desired number of knitting positions in the pattern width. They are operated so that while the hanging registers 6 and 7 are reading the pattern signals stored therein, the other ring registers 6 ¹ and 7 ¹ receive the pattern signals of the next row, which are read out by the reader 3 and passed on through the gates 4a and 4b * When the work of one row of the knitting pattern is completed, the pattern signal reading operation is switched from the registers 6 and 7 to the registers 6 * and 7 *. Now the registers 6 * and 7 'read out the pattern signals, while the registers 6 and 7 receive the pattern signals of the next row of the knitting pattern.

The pattern signals of the red color system and the color system blue that have been read from these ring registers, are then passed through gates 8a and 8b and selective circles 9a, 9b and 9c and to the appropriate needle actuators passed on, which are arranged on the outer peripheral surface of the circular knitting machine, so that the operation of these Kadelbetsteueeinrichtungen is controlled, on the basis of which these Ifedelbetigungseinrichtung knit assigned knitting needles or nioht knit.

In a cough to be knitted, the partial knitting positions all belong to one of the three color systems and no two different color systems overlap at any partial knitting position value "1" is generated when the mother signals of both the red color system and the blue color system have the vert "O" to have; conversely, the value "0" is generated if the pattern signals are either of the red color system or the color system

. have the vert "1" in blue. Thus, two model registers are sufficient

" for this purpose.

Evidence of the completion of a row of knitting can be carried out by the within the control circuit 12 arranged counter 13 counts the machine pulses from the Pulse generator 11 are included, which is provided on the circular knitting machine and a coil for each pass which can generate knitting needle · When the cumulative total of the pulses counted in this way reaches a fixed number, the control circuit 12 transmits a signal to the pattern registers 5 * and 5b, respectively, in order to switch between the signal reading operation and switch the input register to the signal reception operation.

there are 60 needles in each smaller needle actuator interval and 72 needles in each larger needle actuator interval. If the intervals were the same, there would be 63 needles in each interval.

In the case where the needle actuators with are arranged at the same intervals., the first to solder pattern signals of the color system red in the order mentioned to the needle actuating device 10a and the 13th and subsequent pattern signals are supplied to the needle actuator 1Od, the Number of each needle actuator operational assigned needles amounts to 189 per Heine.

In the case where the needle actuators with are arranged at irregular intervals and the needle actuation device 10 * a opposite the first Knitting needle is arranged, the needle actuating device 10'd of the strip knitting needle is arranged opposite. Above all, however, the nine needles, namely the last up to the 189th needle in operation of the needle actuation device 10 · a, the 13th pattern signal, which is the first for the needle actuating device 10'd is the 190th knitting needle after completion of the passage of the nine knitting needles. When a row of knitting has started from the last knitting needle the knitting in this row is completed at the 369th knitting needle and the knitting becomes switched to the next row before the pattern signals to nine knitting needles, namely the thirty-seven to 378th needle that has been delivered. For elimination. of these disadvantages, the invention sees a delay

is when pattern registers and selective registers are used in an adapted number and arrangement for the proportional switching positions of the knitting pattern.

A method and an apparatus for knitting a pattern in an inclined direction will now be described. As already mentioned, according to the method according to the invention, only the pattern signals for an identical row of the knitting pattern are processed at one time when the pattern is being formed. A switchover from the pattern signals for one row to which the next row takes place when the number of machine pulses counted reaches 189 and as a result the signal from the control circuit 12 switches the pattern register 5. If in this case the number of machine pulses required for switching the pattern signals from one row to the next is increased to 190 by adding a pulse, then the pattern signal for the first row is also supplied to the first knitting needle of the second row ; the result that the pattern is canted, as shown in FIG. If the number of Kaschineninpulse for switching is reduced to 188 by removal of a pulse, the pattern is in _dle% © opposite direction to the folded in '· ig. 7 Thus, the pattern in use can be edged by letting Ban lead or lag the time for switching courses with respect to the time actually required to complete knitting in a leg. Furthermore, a straight pattern can be converted into an arabesque numeral by using the relative leading or! «© aeilen de?

by providing an additional circuit 16 in the control circuit 12, the reset pulses for the counter 15 counting the machine pulses can generate, on the basis of which the number of machine pulses required for resetting the counter 13 in accordance with the number of rows of knitting can be controlled.

A method and apparatus will now be described by which the pattern used can be omitted in a given area of knitted fabric and subsequently formed in a vertically rotated or completely reversed direction in that area, or a separate sexton can be formed therein. In the method for omitting the huster used in the given area of the knitted fabric, the signal "1", which causes a knitting needle to execute a knitting movement, is given to each needle actuation device to which yarn of the primary color is supplied, and the signal ' ¹ O ", which causes a knitting needle not to knit, is supplied to any needle actuator associated with the yarn of any other than primary color, without reference to the pattern signals transmitted from the pattern register 5 via the The lobster of the knitting needle positioned opposite a given needle actuator at a given time can be inferred from the number indicated by the machine pulse counters 13 within the control circuit 12. Thus, the omission of the pattern used can be carried out by an additional circuit 1? for a Mu omission between the pattern register 5 and the selective ones
