A relatively great number of embroidering locations with the appropriate embroidering implements are arranged in at least one row. The embroidering implements are capable of being coupled to and uncoupled from the embroidering implement drive of the embroidering machine according to a predetermined repetition and color-change program by electromagnetic actuation devices. Therefore, according to the invention, a so-called group-switching of the embroidering locations, respectively of their electromagnets, is performed such that groups of a few embroidering locations, respectively their electromagnetic actuation devices, form switching groups or units. The electromagnetic actuation devices of each switching unit are connected in parallel at their input sides. An input conductor common to the switching unit connects them to the embroidering location control device. A number of output conductors corresponding to the number of electromagnetic actuation devices per switching unit connects the individual electromagnetic actuation devices at their output sides in series with the embroidering location control device. A minimum of electrical conductors and a very rapid switching of all switching groups is attained with a minimum of power consumption by these measures and by an optimum choice of the number of grouped embroidering locations, in this case for instance four per switching unit.

Embroidering machine

A relatively great number of embroidering locations with the appropriate embroidering implements are arranged in at least one row. The embroidering implements are capable of being coupled to and uncoupled from the embroidering implement drive of the embroidering machine according to a predetermined repetition and color-change program by electromagnetic actuation devices. The pattern and machine-function control of the embroidering machine is performed via a data carrier whose reading and evaluation unit controls a pattern and machine-function control device. Data for the repetition and color-change program are also placed on this data carrier for pattern and machine-function control. Suitable further data are also placed on this data carrier for actuating a switch associated with the reading and evaluation unit for transmitting the repetition and color-change program to an embroidering location control device connected to the electromagnetic actuation devices of the embroidering implements. The employment of the same data carrier hitherto employed for pattern and machine-function control also for the repetition and color-change programs, has the great advantage that all devices for introducing or correcting data on the data carrier, for reading such data and for archiving the data carriers can be retained and that there can be used a relatively uncomplicated design for the control switch and the embroidering location control device.
