    摘要： A sewing machine that can change a trajectory of a needle point without large-sizing a driving mechanism is provided. A needle bar 4 is supported by a needle bar supporter in a manner freely movable up and down relative to a frame. A crank 2 is fixed to an upper shaft 1, rotates with the upper shaft 1, and an output end thereof moves circularly. A crank rod 3 is connected to the crank 2 in a freely rotatable manner. A connection rod 8 is connected to an intermediate portion of the crank rod 3 in a freely rotatable manner, and is connected to the needle bar 4 in a freely rotatable manner. A length of the needle bar 4 and a length from a connecting position of the connection rod 8 and the crank rod 3 to a slider 7 differ. When the crank 2 circularly moves, the connecting position of the connection rod 8 and the crank rod 3 draws a trajectory of an ellipse.

    摘要： A sewing machine moves a needle up and down relative to a cloth based on drive force from a rotating upper shaft to form a stitch. A first output generating unit reciprocates a first output point along an output axis so as to convert the rotational motion of the upper shaft into a linear motion. An assist rod that serves as a connection portion links the first output point with a needle bar. A needle-bar swing unit swings the needle bar. An output shaft moving unit moves a guide that is the output axis in a cloth feeding direction in accordance with the motion of the needle-bar swing unit. The assist rod changes the inclination in accordance with the movement of the output axis, and reciprocates the needle bar in substantially parallel with the output axis while maintaining the inclination.

    摘要： Bei einem Antrieb für eine Näbmaschine, insbesondere eine Industrienähmaschine, mit einer elektromagnetisch direkt angetriebenen Nadelstange, wobei gesondert hiervon mittels eines eigenen Motors eine untere Welle angetrieben wird, von welcher wenigstens der Antrieb von Greifer und Transporteur abgeleitet wird, ist vorgesehen, daß an der Nadelstange (1) eine Mehrzahl von Magneten (2) befestigt ist, wobei aufeinanderfolgende Magneten (2) jeweils entgegengesetzte Magnetisierungen aufweisen, daß durch einen Luftspalt (3) von diesen Magneten (2) getrennt ortsfest eine Mehrzahl von Spulen (Windungen 9) angeordnet ist, deren Polabstand zum Abstand der Magneten (2) korrespondiert, und daß die Bestromung der Spulen (Windungen 9) derart gesteuert wird, daß die Nadelstange (1) eine lineare Auf- und Abbewegung entsprechend einem vorgebbaren Geschwindigkeits- bzw. Beschleunigungsprofil ausführt.

    摘要： A sewing unit (1) for sewing seams located multidimensionally in space has a sewing head. The latter has a needle bar upper part (12) in which a needle bar (11) is mounted so as to be driven up and down along its longitudinal axis (13). At least one sewing needle (9, 10) is held, as a stitch-forming tool, on the needle bar (11). The needle bar upper part (12) is mounted in a pivotable manner in a sewing head upper part (14) so as to be driven about the needle bar longitudinal axis (13). At least one gripper is mounted, as a stitch-forming tool driven synchronously with the sewing needle (9, 10), on a gripper lower part (17) of the sewing head. The gripper lower part (17) is mounted in a pivotable manner in a sewing head lower part (18) so as to be driven about the needle bar longitudinal axis (13) synchronously with the needle bar upper part (12). Motor components (19, 69) for driving the up and down movement of the needle bar (11), for pivoting the needle bar upper part (12), for driving the gripper synchronously with the needle bar (11) and for pivoting the gripper lower part (17) are arranged outside the needle bar upper part (12) and outside the gripper lower part (17). This results in a sewing unit with which even parts that are to be sewn in a topographically irregular manner are made accessible for sewing.
