Abstract: A loom having a first drive motor (10), which for instance drives a batten (13), and having at least one second drive motor (44), which drives a dobby (46), is provided with a control and regulating device (48), which forms a rotational angle course for a virtual synchronization shaft of the loom and communicates such rotational angle course to respective control and regulating units (49, 51) of each of the drive motors (10, 44), which synchronize the drive motors in at least one angular position relative to the virtual synchronization shaft.
