ABSTRACT:
A process for accurately determining the needle zero point of the sewing machine (4) of an automatic sewing unit (1) in relation to a positioning opening (12) of a fabric holder (10). The fabric holder (10) is connected to two feed parts (13, 14) displaceable along a straight guide rail (15) via at least two connecting rods (7, 8) of a coordinate transmission (9), such that the displacement of the feed parts (13, 14) brings about corresponding X/Y movements of the fabric holder (10), and wherein the displacement of the feed parts (13, 14) along the guide rail (15) is performed by means of drives (16, 17), which can be actuated by means of an electronic control device (6) containing at least one memory (26). To determine the needle zero point very accurately in such an automatic sewing unit (1) without performing a complicated mechanical adjustment, only an approximate setting of the sensor-monitored zero position of the fabric holder (10) is performed at first, and then an electronic correction of this value is subsequently performed, wherein the correction values are stored in a memory (26) of the control device (6) and they are correspondingly taken into account during the subsequent sewing and embroidering processes.
