is an inventive arrangement for controlling a Guide rail applied. This eliminates all of the disadvantages described above for pattern chains. A pattern to be created is digitally transferred, for example, to a data carrier, e.g. a kind of jacquard card. In order to Elektro'magnete are controlled in a known manner, which cause the movement of the spacers.

Further advantages and developments of the invention will emerge from the description that follows.

Due to the different widths (widths ij_, I2, I4, ISS, I ₁ O) spacers 1, 2, 4, 8 and l6 the locations of different value are realized. In the binary system, the spacer 1 represents the value? °, the spacer 2 the value 2 * etc. The spacers are pulled from the rest position 2f> into the working position 26 by the associated electromagnets Ml, M2, M4, M8 and MI6 when excited. In the example shown, the spacers 1, 4 and 16 are in the working position, which corresponds to a binary number LOLOL.

To convert this binary number into a translation, the cam disk 20 is rotated and displaced the spacers 1, 4 and 16 against the bolt 21. Thereupon the bolt 21, which is pressed by the spring 23 against the stop 22, becomes the groove of the bolt 21 - shifted upwards by the sum of the widths of the spacers 1 \ + I4 + 1 ^ 5: the digital value is converted into a graduated translation. If no spacer is in the working position, 30 the bolt is not moved or is moved by a minimum fixed value when the cam disk is rotated. A roller 28 and a plate 2? arranged. The displacement of the bolt 21 can be used to control various processes.

With the bolt, for example, the guide rail can be a Warp knitting machine can be controlled. The guide rails are known to be used for making patterns during of the knitting process shifted.

A pattern to be acted is based on digital values a data carrier, e.g. a kind of jacquard card. The electromagnets are controlled by the data carrier, which select the spacers. For controlling the warp knitting machine an arrangement according to the invention is necessary for each guide rail. Any inventive The arrangement is narrow so that they can all be lined up closely together are. -.

The speed at which the cam disc rotates is from The work rhythm of the warp knitting machine determines that too the query times of the information carrier determined.
