    • A looper and knife driving mechanism of sawing machine, wherein an upper looper (30) and a lower looper (40) are provided under a needle plate (8), knife tips (31, 41) are disposed in the same direction so as to pass through the front side side-face of a needle (8) as viewed in the sawing direction, and the upper looper (30) and lower looper (40) are driven so that the routes thereof move on those surfaces substantially in parallel with each other in order to provide both the lock stitch and over-edge chain stitch functions and, in addition, form the sawing at once by a single sawing machine, the rotating motion of the upper shaft (S1) of the sawing machine is converted into a vertical motion through a motion converting mechanism (71) interlocked with the rotating motion so as to cut off a cloth edge (5c) by the vertical motion using an upper knife (72) and a lower knife (73) moving in association with the upper knife (72), the upper knife (72) being guided slidably by a female driving part (74) (710) pivotally supported by a machine frame FR and the motion converting mechanism (71) being connected to the upper knife (72) through a clutch (75)(750), whereby the clutch (75)(750) transmits a power to the upper knife (72) when the knife of the knife driving part (74)(710) is operated and drives the female driving part (74)(710) to an escape position when the knife is not operated so as to cut off a power to the upper knife (72).

    • Das einstellbare Kopfmodul (21) ist plattenförmig ausgebildet. Es liegt schwenkbar auf zwei Sicken (41), entlang denen es zusätzlich verschiebbar ist. Die exakte Lage der Nadel (14) lässt sich damit sowohl in Nährichtung (A) als auch quer dazu (Richtung B) exakt ein- und verstellen.
    • 该缝纫机具有可调缝纫头模块(21)。 模块(21)在一个方向(A)上在水平枢轴安装件(41)上摆动,并且在载体臂(19)上沿着另一方向(B)在安装件上轴向滑动。 水平枢轴安装由载体臂(19)表面上的至少一个肋和头模块(21)中的至少一个水平滚珠(41)形成。 缝纫头模块(21)具有带有至少一个成形花纹(41)的承载板(35)。 切口开口位于滚珠(41)中,或在多个滚珠(41)之间,通过它们夹紧螺栓(45)。 螺纹钻孔可以在承载臂(19)处的肋的侧面或肋之间,以获取夹紧螺栓(45)。螺纹钻孔(49)使头部模块(21)绕枢轴摆动, 在与至少一个卷边(41)的间隙处在承载板(35)处,以将扭转成承载臂(19)中的钻孔的定位螺钉。 压力弹簧在承载臂(19)和承载板(35)之间张紧。 缝纫头模块(21)的轴向和水平滑动运动(B)穿过缝纫头模块(21)的垂直狭缝(53),以便在承载臂(19)处取得偏心销(55)。
