Abstract

The invention relates to a yarn supply device group for attaching to a textile machine, in particular a ring knitting machine with electrically controllable switching and actuating devices in every supply device which are connected in a signal-transmitting circuit by a bunch of lines common to all supply devices to a central control mechanism. Previously, every supply device in the group had to be 'marked' manually prior to the start of operation. In addition, a bunch of lines with large dimensions was necessary, since each supply device needed at least one separate line. In the invention, manual 'marking' is not needed, since in each supply device an electronic switching arrangement which contains a writable and readable memory is associated with the switching or actuating devices, can be supplied with an individual address from the central control mechanism, and after having been supplied the address can be controlled addresslike, and for connection of the supply device to the central control mechanism a small-dimensioned bunch of lines can be provided since the switching arrangements of all supply devices are connected in the same manner to the bunch of lines.
