Abstract

Eine Nähmaschine hat eine Transporteinrichtung (14) zum intermittierenden Vorschub von Nähgut. Die Transporteinrichtung (14) hat mindestens einen oberen Transporteur (15) und mindestens einen unteren Transporteur (16, 17) zum intermittierend reibschlüssigen Vorschub-Kontakt mit einer Ober- bzw. Unterseite des Nähguts. Zur Verstellung einer Vorschublänge der Transporteure (15 bis 17) dienen mechanische Obertransport- und Untertransport-Verstelleinrichtungen. Diese Verstelleinrichtungen werden über Verstellantriebe verstellt. Eine Steuereinrichtung steht mit dem Untertransport-Verstellantrieb und dem Obertransport-Verstellantrieb in Signalverbindung und hat eine Speichereinrichtung. In dieser sind Daten zu abzuarbeitenden Nähsequenzen und diesen Nähsequenzdaten zugeordnet Einstelldaten zur unabhängigen Ansteuerung der Verstellantriebe während des Abarbeitens der Nähsequenz abgelegt. Es resultiert eine Nähmaschine, bei der die Flexibilität des Nähgutvorschubs zur Anpassung an unterschiedliche Nähanforderungen erhöht ist.

A sewing machine has a transport device (14) for the intermittent feed of sewing material. The transport device (14) has at least one upper feed dog (15) and at least one lower feed dog (16, 17) for the intermittently frictional feed contact with a top or bottom side of the sewing material. To adjust a feed length of the transporters (15 to 17) serve mechanical top transport and bottom feed adjustment. These adjusting devices are adjusted by adjusting drives. A control device is in signal communication with the lower transport adjustment drive and the upper transport adjustment drive and has a storage device. In this, data to be processed sewing sequences and this sewing sequence data associated adjustment data for independent control of the adjusting drives are stored during the execution of the sewing sequence. The result is a sewing machine, in which the flexibility of the Nähgutvorschubs is increased to adapt to different sewing requirements.
