Abstract (en)
Traverse (27) of the fabric in the x and y directions on a sewing or embroidery machine is controlled through a fabric movement sensor (32) and arranged so that any deviations from the required movement are corrected over a number of successive sewing steps or conveying cycles. The central control unit (13) uses the sensor signals in step with the conveying cycles and carries out a summation according to a prearranged program. <??>Also claimed is the arrangement of a sensor (32) below the stitch plate (21) to provide data on fabric movement. The sensor can be a CCD matrix or miniature camera with image processing facilities. The sensor operates through a protective window (36) near the needle hole (23) and includes a light source. The fabric is held against the window by a presser foot or roller.
Abstract (de)
Das Verfahren und die Vorrichtung zum Regeln des Stofftransportes bei einer Näh- oder Stickmaschine (1) nutzen die Informationen eines unter der Stichplatte (21) angeordneten Positions- oder Bewegungssensors (33). Die Steuerung der Nähmaschine (1) ermittelt aus den periodisch eingelesenen Sensorsignalen Abweichungen der tatsächlichen Vorschubwerte des Nähgutes von den entsprechenden Sollwerten. Anhand dieser Informationen werden die Vorschubgrössen in der Weise geregelt, dass die Abweichungen sich im Mittel aufheben. <IMAGE>
