Abstract

Eine Nähmaschine (1) dient zum Vernähen zweier Nähgutteile unter Einarbeitung von Mehrweite. Die Nähmaschine (1) hat ein Gehäuse (2, 3, 4), eine über einen Nadelantrieb (7) auf- und abgehend angetriebene Nadelstange (9) mit einer Nadel. Zum Vorschieben der beiden Nähgutteile dienen ein unterer Stoffschieber und ein oberer Stoffschieber. Eine Hubeinrichtung (26, 32) dient zum intermittierenden Anheben des oberen Stoffschiebers relativ zum unteren Stoffschieber während des Nähbetriebs. Die Hubeinrichtung (26, 32) umfasst einen vom Nadelantrieb unabhängigen und am Gehäuse (2, 3, 4) festgelegten Hub-Antriebs-Motor (26), der mit einer Hub-Antriebs-Steuereinrichtung (30) zusammenwirkt. Es resultiert eine Nähmaschine, bei der Einstellmöglichkeiten für das intermittierende Anheben des oberen Stoffschiebers während des Nähbetriebs flexibler gestaltet sind.

A sewing machine (1) is used to sew two Nähgutteile incorporating fullness. The sewing machine (1) has a housing (2, 3, 4), a via a needle drive (7) up and down driven needle bar (9) with a needle. For advancing the two workpieces are used a lower feed dog and an upper feed dog. A lifting device (26, 32) serves for intermittently lifting the upper feed dog relative to the lower feed dog during the sewing operation. The lifting device (26, 32) comprises a non-driven by the needle drive and the housing (2, 3, 4) fixed stroke drive motor (26) which cooperates with a stroke drive control device (30). The result is a sewing machine, are made more flexible in the settings for the intermittent lifting of the upper feed dog during the sewing operation.
